Name: Marion D. Dungo JOURNAL ENTRY No. 1 Key concepts: Solution can be classified as gaseous, solid or liquid. Solutions are also classified as dilute and concentrated based on the relative amounts of components of the solution.
3 Things I found out: First I found out what is the homogenous and heterogenous, second, I found out the meaning of saturated, unsaturated and supersaturated, and lastly, I found out that everything around me is a solution.
2 Interesting things based on your own thoughts: First I just knew that if the light passes through the solution it is homogenous, second I just knew that milk is not a solution.

Everything around me is a solution I say it with conviction Solution can be dilute and concentrated so don't get excited it is not exaggerated.
Learning two different mixtures can correct your solution failures. That's why learning solution can change our nation.
Solution in the air solution everywhere solution in the water it depends on the weather.
Let's thank God for solution, because it is His creation.
Key concepts: In chemistry, a solution is a homogeneous mixture composed of only one phase.
And their are 3 types of solutions 1. gaseous solution- includes gases or vapors dissolved in one another.two or more gases can form a solution. Air is an example of a gaseous solution. When dry is made up of oxygen gas dissolved in nitrogen gas.
2. liquid solution-contain a liquid solvent in which gas, liquid, or solid is dissolved. Water is the most common liquid solution. Many things can be dissolved in it. Table salt is an example of a solid dissolved in a liquid. A liquid and a gas can also be dissolved in a liquid solution.
3. A solid solution-is a mixture of solids spread equally throughout one another. Metal is an example of a solid solution at room temperature.
3 Things I found out: First, I found out that our first lesson in chemistry is about solution, Second, I found out the meaning of solution and solution is a homogeneous mixture of two or more substances evenly distributed in each other, And last, I found out that after learning the meanings and types of solution and their characteristics we had a simple experiment that has a connection in our topic.
2 Interesting things based on your own thoughts: First, i just knew through our experiment which of the three ( salt with water , sand with water and soy sauce with water) dissolved the solute completely and the answers are the salt with water and the soy sauce with water, Second, i just knew that through filtration we separate sand and water and that is the proof that the solute did not dissolve in the water.

Name:Andrea Lorraine B. Macandile Sir Andrew Bondad JOURNAL Entry No. 1
Key Concept: In chemistry, a solution is a homogeneous mixture composed of only one phase. In such a mixture, a solute is a substance dissolved in another substance, known as a solvent. The solvent does the dissolving. The solution more or less takes on the characteristics of the solvent including its phase, and the solvent is commonly the major fraction of the mixture. The concentration of a solute in a solution is a measure of how much of that solute is dissolved in the solvent.

1 Question I still have: Is blood homogeneous or heterogeneous?
Insights: All around me is solution. Imagine without solution, can we get any benefits in it? God is so powerful that He made things perfect and has a purpose, so we should take care of it. I learned a lot.
JOURNAL ENTRY No.1 Key Concepts: Solvent is a liquid, solid, or gas that dissolves another solid, liquid, or gaseous solute, resulting in a solution that is soluble in a certain volume of solvent at a specified temperature. Common uses for organic solvents are in dry cleaning as paint thinners as nail polish removers and glue solvents (acetone, methyl acetate, ethyl acetate), in spot removers in detergents (citrus terpene ), in perfumes (ethanol), nail polish and in chemical synthesis. The use of inorganic solvents (other than water) is typically limited to research chemistry and some technological processes. Things I found out 1. I found out that if i mix sand and H2o it will just go at the end of the container because Solute is manier than solvent that’s why it goes down but it also mixes in the water and it is also an heterogenous mixture. 2. I also found out that if you mix salt and water the salt really mixes in the water properly So it is homogenous mixture. 3.i also found out that soy sauce mixes in the water and when I place it in the sunlight It’s color is red Interesting thing’s based on my own thoughts: The interesting thing I saw was the soy sauce that turn red on the water And I can imagine how powerful and wonderful our GOD is.

Key Concept:A solution is a homogeneous mixture of two or more substances. A solution may exist in any phase such as solid liquid or gas. # things i found out 1.I found out that milk is not a mixture neither is it a solution but a type of colloid. 2.I learned that everything around us just isn't there to be there but everything has a purpose and has its own kind of complexity. 3.I found out that no two things in this world are alike. Everything has its differences from its physical appearance down to its molecule structure.
Interesting thing's based on my thoughts: 1. I learned that everything around me is so complex and so different compared to each other and makes me wonder how and why did God make such things. 2 I learned how to appreciate things around me better. Because even when I'm making juice I still watch how the solute dissolved in the solvent and try to recap what we learned on class that day.
Insights: Although I do think chemistry will be so much harder i still think it will still be fun to learn. And besides I'm the one who'll benefit from it anyways.
Name:Marvin B. Samar Sir Andrew Bondad JOURNAL ENTRY No. 1 Key Concept: Solutions are homogeneous mixture in which one substance is said to have been dissolve in the other. The dissolve substance may be present as individual molecules ions throughout the other substance. Solutions are also classified as dilute and concentrated based on the relative amounts of components of the solution.
3 Things I found out: -Air dissolves in water. Thus, a fish breathes oxygen in air that is dissolved in water. -Milk looks homogeneous when rays of light are passed through it. -Mixture is a material consisting of two or more kinds of matter, each of which retains its own characteristic properties.

Key Concept: Colloid is a substance microscopically dispersed evenly throughout another substance. A colloidal system consists of two separate phases: a dispersed phase or internal phase and a continuous phase (or dispersion medium) in which the colloid is dispersed. A colloidal system may be solid, liquid, or gas.
3 Things I found out: ☼ Colloid's particles are in a dispersed phase. ☼ Colloids can be separated in many various ways. ☼ Colloids can be solid liquid and gas.
2 Interesting things based on my thought. δ Because of the dispersed particles inside of colloid when light is pointed at it the beam of light will scatter and the color of the substance may change into a brighter color. δ A substance is determined to be colloid only if the right properties match.
1 Question I still have Can colloid be heterogeneous.
Insight: Poem from the encyclopedia
Colloids are several sols. Are they colloidal? Do you care?
Can I cast a meter, committed so pupils might see Newly pleasing allusions, somehow nurturing, and oh yet revealed free? Frosts or creams look all too absolute. But is breezes? Gelatines, rimes? - or stiffens, colloids? Darn! I deserted freezes! I reason frostings and similarly ointments, but rightly ought I - crank concepts so - notations drafted from equations spry?
Key Concept: Colloids is a dispersion of particles of one substance (the dispersed phase) throughout a dispersing medium made of another substance. Thus colloids are classified based on the phases of both the dispersed material and the dispersing medium.
3 Things I found out: First that I found out that Milk is a colloid, because the solid particles in milk are evenly spread throughout a liquid. Second, I found out How are Colloids Utilized in Technology, Human Body and Environment.And Third, I found out what are the 3 properties do colloids have and the answers are Tyndall Effect - the scattering of light due to the particles of colloidal solution. Brownian Movement - the particles moved in Jerky. Jerky , random motion which is due to the collision of the rapidly moving particles. Adsorption - colloidal particles adsorbed ions or other charge particles like gasses and liquids.
2 Interesting things based on my own thoughts: First, I just knew that through our experiment which is the Magic Mayonnaise there comes the time that when we already start the procedure , record our data and then our conclusion , that there for we conclude that our hypothesis is not correct or in other words it is rejected, we need to go back to the hypothesis and make a new one. Second, I just research whats wrong with our Magic Mayonnaise then based on what I read the ingredients must be; 2 egg yolks 3/4 teaspoon salt 1/2 teaspoon powdered mustard 1/8 teaspoon sugar Pinch cayenne pepper 4 to 5 teaspoons lemon juice or white vinegar 1-1/2 cups olive or other salad oil 4 teaspoons hot water
1 Question still I have: What is the importance of colloids in our daily life?
Answer to my Question: The Importance of Colloids in our Daily Life is to have use it on right time.
Insight: Colloid is indeed important in our daily life, We wake up in the morning and pour milk onto our cereal (milk is an emulsion, which is a type of liquid-liquid colloid), then we will take a shower and once were done we might put some gel in our hair (gels are another type of solid-liquid colloid). After all of that were ready to go to school and in our classroom we pull out our pens and wright something in our notebooks (the ink in our pen is another type of liquid-solid colloid). Our day is about an hour old and we've already had some pretty definite interactions with colloids.

Key Concept: Colloid substances are involved in many biological processes. A colloidal system consists of two separate phases: a dispersed phase (or internal phase) and a continuous phase (or dispersion medium) in which the colloid is dispersed. A colloidal system may be solid, liquid, or gas.Some colloids are translucent because of the Tyndall effect, which is the scattering of light by particles in the colloid. Other colloids may be opaque or have a slight color. Colloidal solutions (also called colloidal suspensions) are the subject of interface and colloid science. This field of study was introduced in 1861 by Scottish scientist Thomas Graham.

1 question still I have: -can we separate colloids through decantation?
Insights: We can get many benefits in colloids. We can apply it to our daily life.Colloids display intriguing transitions between gas, liquid, solid and liquid crystalline phases. Example when we are applying gel in our hair gel is a type of colloid. Don't forget to thank God that He made everything perfect like colloids... :)
Name: Andrea Lorraine B. Macandile Sir Andrew Bondad Journal Entry No. 2
Key Concept:Something is a MIXTURE if it contains two (or more) substances that are not chemically joined together. The substances in a mixture can often be easily separated from one another. A PURE substance only contains one material and so cannot be separated in any way (unless a chemical reaction takes place) Different ways of separating mixtures 1 A magnet can be used to separate IRON from SAND. How it works: The magnet sticks to the iron but not to the sand 3. Filtering (filtration) can be used to separate a solid (or suspension) from a liquid. How it works: The liquid (and anything dissolved in the liquid) passes through holes in the filter paper but the solid particles are too big and get stuck. Example: Filtration would be used to separate the dirt from some salty water. 4. Evaporation can be used to separate a dissolved SOLUTE from a SOLUTION Example: Evaporation would be used to obtain some pure salt from salty water. How it works: When salty water is warmed the water evaporates leaving behind crystals of salt. MAKING ROCK SALT PURE Rock salt is a MIXTURE of several substances. In order to make pure salt it is necessary to remove the INSOLUBLE dirt from the SOLUBLE salt. [Note: The method described below could be used to separate any two substances when one of them can dissolve in water and the other cannot] 1. CRUSH the rock salt using a mortar and pestle. This makes the salt dissolve more easily. 2. STIR the crushed salt into a beaker of warm water. The salt will DISSOLVE into the water but the dirt, which is insoluble in water, will not. 3. FILTER the mixture. The dirt will get caught in the filter paper as a residue and the clear SALTY WATER will drip through and form the filtrate. 4. Warm the filtrate in an evaporating basin. The water will EVAPORATE leaving behind pure salt crystals. The heat is stopped BEFORE all of the water has evaporated. This makes the salt more pure and helps prevent the evaporating basin from cracking.. The last little bit of salty water is filtered out.

3 Things I found out: -separation is a processes of any scale that separates components of a mixture from each other without substantial chemical modification. -separations are carried out based on differences in chemical properties such as size, shape, mass, or chemical affinity between the constituents of a mixture, and are often classified according to the particular differences they use to achieve separation. -there are many separation techniques
2 Interesting things based on my own thoughts: -we can separate salt and water through evaporation -heat is applied to quicken evaporation but NOT to cause decomposition.
1 Question I still have: -can we separate oil and water.
Insights: There are many separation techniques there are many benefits we can get in it. I have learned a lot like when we separate water and salt through evaporation and separating charcoal, salt, and water we separate them through filtration we saw the crushed charcoal in the filtrate paper when we filtrate it we saw the clear water and when we heated the water to quicken evaporation we saw the water evaporating and the salt remains, the separation process is called crystallization. I learned a lot in the lesson and experiments.

2 Interesting Things based on my own thoughts: First, when we have an experiment on how to separate the mixture of salt,charcoal,and water we use the method of filtration,when we filter it in the filter paper the residue remains in the filter paper and the filtrate goes to the evaporating dish.Next,it involves the method of crystallyzation, when the filtrate heated and boilsit turns to gas and the water crystallyze.
1 Question I still have: Can oil be separated from water?
Key Concept: A Mixture is a combination of two or more substances that are not chemically united and do not exist in fixed proportions to each other.
3 Things I found out: First, I found out that Mixtures can be separated into their constituents by using physical methods. Second, I found out that if you put the catalyst in the beaker the water will boil fast. Third, In the Filtration, inside the filter paper is what you called residue and the clear water coming out to the funnel is called filtrate.
2 Interesting things based on my own thoughts: First, I just knew that when we had an experiment using charcoal,salt and water, we can still separate the crushed coal and salt using the process of filtration. Second I just knew that when we used the funnel to filter charcoal and salt, in the filter paper the residue is the charcoal left and I am amazed that even the water is color black but when we filter it the water that came out to the funnel is color white and that is called filtrate.

Key Concepts:
Solvent is a liquid, solid, or gas that dissolves another solid, liquid, or gaseous solute, resulting in a solution that is soluble in a certain volume of solvent at a specified temperature. Common uses for organic solvents are in dry cleaning as paint thinners as nail polish removers and glue solvents (acetone, methyl acetate, ethyl acetate), in spot removers in detergents (citrus terpene ), in perfumes (ethanol), nail polish and in chemical synthesis. The use of inorganic solvents (other than water) is typically limited to research chemistry and some technological processes.
Things I found out
1. I found out that if i mix sand and H2o it will just go at the end of the container because
Solute is manier than solvent that’s why it goes down but it also mixes in the water and it is also an heterogenous mixture.
2. I also found out that if you mix salt and water the salt really mixes in the water properly
So it is homogenous mixture.
3.i also found out that soy sauce mixes in the water and when I place it in the sunlight
It’s color is red
Interesting thing’s based on my own thoughts:
The interesting thing I saw was the soy sauce that turn red on the water
And I can imagine how powerful and wonderful our GOD is.

Key Concept:A solution is a homogeneous mixture of two or more substances. A solution may exist in any phase such as solid liquid or gas.
# things i found out
1.I found out that milk is not a mixture neither is it a solution but a type of colloid.
2.I learned that everything around us just isn't there to be there but everything has a purpose and has its own kind of complexity.
3.I found out that no two things in this world are alike. Everything has its differences from its physical appearance down to its molecule structure.
Interesting thing's based on my thoughts:
1. I learned that everything around me is so complex and so different compared to each other and makes me wonder how and why did God make such things.
2 I learned how to appreciate things around me better. Because even when I'm making juice I still watch how the solute dissolved in the solvent and try to recap what we learned on class that day.
Insights:
Although I do think chemistry will be so much harder i still think it will still be fun to learn. And besides I'm the one who'll benefit from it anyways.

Key Concept:
Solutions are homogeneous mixture in which one substance is said to have been dissolve in the other. The dissolve substance may be present as individual molecules ions throughout the other substance. Solutions are also classified as dilute and concentrated based on the relative amounts of components of the solution.
3 Things I found out:
-Air dissolves in water. Thus, a fish breathes oxygen in air that is dissolved in water.
-Milk looks homogeneous when rays of light are passed through it.
-Mixture is a material consisting of two or more kinds of matter, each of which retains its own characteristic properties.

Key Concept: Colloid is a substance microscopically dispersed evenly throughout another substance.
A colloidal system consists of two separate phases: a dispersed phase or internal phase and a continuous phase (or dispersion medium) in which the colloid is dispersed. A colloidal system may be solid, liquid, or gas.
3 Things I found out:
☼ Colloid's particles are in a dispersed phase.
☼ Colloids can be separated in many various ways.
☼ Colloids can be solid liquid and gas.
2 Interesting things based on my thought.
δ Because of the dispersed particles inside of colloid when light is pointed at it the beam of light will scatter and the color of the substance may change into a brighter color.
δ A substance is determined to be colloid only if the right properties match.

Key Concept:
Colloids is a dispersion of particles of one substance (the dispersed phase) throughout a dispersing medium made of another substance. Thus colloids are classified based on the phases of both the dispersed material and the dispersing medium.
3 Things I found out:
First that I found out that Milk is a colloid, because the solid particles in milk are evenly spread throughout a liquid. Second, I found out How are Colloids Utilized in Technology, Human Body and Environment.And Third, I found out what are the 3 properties do colloids have and the answers are Tyndall Effect - the scattering of light due to the particles of colloidal solution. Brownian Movement - the particles moved in Jerky. Jerky , random motion which is due to the collision of the rapidly moving particles. Adsorption - colloidal particles adsorbed ions or other charge particles like gasses and liquids.
2 Interesting things based on my own thoughts:
First, I just knew that through our experiment which is the Magic Mayonnaise there comes the time that when we already start the procedure , record our data and then our conclusion , that there for we conclude that our hypothesis is not correct or in other words it is rejected, we need to go back to the hypothesis and make a new one. Second, I just research whats wrong with our Magic Mayonnaise then based on what I read the ingredients must be;
2 egg yolks
3/4 teaspoon salt
1/2 teaspoon powdered mustard
1/8 teaspoon sugar
Pinch cayenne pepper
4 to 5 teaspoons lemon juice or white vinegar
1-1/2 cups olive or other salad oil
4 teaspoons hot water
1 Question still I have:
What is the importance of colloids in our daily life?
Answer to my Question:
The Importance of Colloids in our Daily Life is to have use it on right time.
Insight:
Colloid is indeed important in our daily life,
We wake up in the morning and pour milk onto our cereal (milk is an emulsion, which is a type of liquid-liquid colloid), then we will take a shower and once were done we might put some gel in our hair (gels are another type of solid-liquid colloid). After all of that were ready to go to school and in our classroom we pull out our pens and wright something in our notebooks (the ink in our pen is another type of liquid-solid colloid). Our day is about an hour old and we've already had some pretty definite interactions with colloids.

Key Concept:Something is a MIXTURE if it contains two (or more) substances that are not chemically joined together.
The substances in a mixture can often be easily separated from one another.
A PURE substance only contains one material and so cannot be separated in any way (unless a chemical reaction takes place)
Different ways of separating mixtures
1 A magnet can be used to separate IRON from SAND.
How it works: The magnet sticks to the iron but not to the sand
3. Filtering (filtration) can be used to separate a solid (or suspension) from a liquid.
How it works: The liquid (and anything dissolved in the liquid) passes through holes in the filter paper but the solid particles are too big and get stuck.
Example: Filtration would be used to separate the dirt from some salty water.
4. Evaporation can be used to separate a dissolved SOLUTE from a SOLUTION
Example: Evaporation would be used to obtain some pure salt from salty water.
How it works: When salty water is warmed the water evaporates leaving behind crystals of salt.
MAKING ROCK SALT PURE
Rock salt is a MIXTURE of several substances.
In order to make pure salt it is necessary to remove the INSOLUBLE dirt from the SOLUBLE salt.
[Note: The method described below could be used to separate any two substances when one of them can dissolve in water and the other cannot]
1. CRUSH the rock salt using a mortar and pestle. This makes the salt dissolve more easily.
2. STIR the crushed salt into a beaker of warm water. The salt will DISSOLVE into the water but the dirt, which is insoluble in water, will not.
3. FILTER the mixture. The dirt will get caught in the filter paper as a residue and the clear SALTY WATER will drip through and form the filtrate.
4. Warm the filtrate in an evaporating basin. The water will EVAPORATE leaving behind pure salt crystals. The heat is stopped BEFORE all of the water has evaporated. This makes the salt more pure and helps prevent the evaporating basin from cracking..
The last little bit of salty water is filtered out.
3, 2, 1...
3 Things I found out:
-separation is a processes of any scale that separates components of a mixture from each other without substantial chemical modification.
-separations are carried out based on differences in chemical properties such as size, shape, mass, or chemical affinity between the constituents of a mixture, and are often classified according to the particular differences they use to achieve separation.
-there are many separation techniques
2 Interesting things based on my own thoughts:
-we can separate salt and water through evaporation
-heat is applied to quicken evaporation but NOT to cause decomposition.
1 Question I still have:
-can we separate oil and water.
Insights:
There are many separation techniques there are many benefits we can get in it. I have learned a lot like when we separate water and salt through evaporation and separating charcoal, salt, and water we separate them through filtration we saw the crushed charcoal in the filtrate paper when we filtrate it we saw the clear water and when we heated the water to quicken evaporation we saw the water evaporating and the salt remains, the separation process is called crystallization. I learned a lot in the lesson and experiments.

"COLLOIDS"
Key Concepts:
Colloids is a heterogeneous mixture wherein the solute-like particles
do not settle out.
3 Things I Fount Out:
First, colloids are different from the ordinary solutions and suspensions
because of their distinct characteristics. Second, the particles in the colloids
are suspended in the dispersed medium and do not settle down like the suspension.
Third, colloids exhibit the Tyndall Effect.
2 Interesting Things Based on my own Thoughts:
I thought for every colloids that has been prepared is there are some
methods to break it down into colloidal particles in the dispersed medium.
And I thought that some colloids source of diseases.

First, I found out that mixtures can be separated into many physical methods.Second, I also found that it is the collage of different samples of mixtures like mayonnaise,ink,glue,muddy water,air and many more.And lastly,we can use the different techniques based on their properties.
2 Interesting Things based on my own thoughts:
First, when we have an experiment on how to separate the mixture of salt,charcoal,and water we use the method of filtration,when we filter it in the filter paper the residue remains in the filter paper and the filtrate goes to the evaporating dish.Next,it involves the method of crystallyzation, when the filtrate heated and boilsit turns to gas and the water crystallyze.

Key Concept:
A Mixture is a combination of two or more substances that are not chemically united and do not exist in fixed proportions to each other.
3 Things I found out:
First, I found out that Mixtures can be separated into their constituents by using physical methods. Second, I found out that if you put the catalyst in the beaker the water will boil fast. Third, In the Filtration, inside the filter paper is what you called residue and the clear water coming out to the funnel is called filtrate.
2 Interesting things based on my own thoughts:
First, I just knew that when we had an experiment using charcoal,salt and water, we can still separate the crushed coal and salt using the process of filtration. Second I just knew that when we used the funnel to filter charcoal and salt, in the filter paper the residue is the charcoal left and I am amazed that even the water is color black but when we filter it the water that came out to the funnel is color white and that is called filtrate.

"solution"
Key concept:
In chemistry, a solution is a homogeneous mixture composed of only one phase. In such a mixture, a solute is a substance dissolved in another substance, known as a solvent. The solvent does the dissolving. The solution more or less takes on the characteristics of the solvent including its phase, and the solvent is commonly the major fraction of the mixture. The concentration of a solute in a solution is a measure of how much of that solute is dissolved in the solvent.
3Things I found out that:
sand and water can be separated in filtration and I found out that the soy sauce and water if I mixed it the soy sauce will be easier to be seen in the water and i found out the different types of solutions.

"colloid"
Key concept:
The dispersed-phase particles have a diameter of between approximately 1 and 1000 nanometers.[2] Such particles are normally invisible in an optical microscope, though their presence can be confirmed with the use of an ultramicroscope or an electron microscope. Homogeneous mixtures with a dispersed phase in this size range may be called colloidal aerosols, colloidal emulsions, colloidal foams, colloidal dispersions, or hydrosols. The dispersed-phase particles or droplets are affected largely by the surface chemistry present in the colloid.
3Thing I found out that:
In hemodialysis, the bloodstream is diverted from its normal course in body and pumped through a dialyzing tube with the semi-permealbe membrane. In our waterways, the disposal of detergents and other pollutants can act as protective colloids that stbilize foam formation.com. Suspended particles in air are commonly called particulates.
