Introduction
Matter? Pure Substances? Mixtures? What are all of these words?!
Well, these are all words of SCIENCE! Matter! Pure Substances! Mixtures! Particles! Solutions! Many, many more. These are just some of the things that make up the things around you. All amazing and interesting things, but maybe people haven't been looking into it enoguh. You have become a scientist and this is your chance to become a SCIENCE PRODIGY! Have FUN!
Task
You are a famous scientist, working at a huge laboratory in the city with your fellow scientists. Your mission is to learn more about MATTER in general. You will have to learn and complete "FUN" activities about pure substances, mixtures, solutions, concentration/saturation and the PARTICLE theory. You will conduct series of experiments, find enough research and evidence and complete a quiz in order test your knowledge.
Process
Activities
Task #1
Part 1: For your first activity, you will have to conduct an experiment to see the world of solubility, solutions, solutes and solvents. In the experiment below, you will learn about how temperature can affect solubility. Make sure you conduct this experiment with all the materials and following all the instructions.
Materials you will need:
- 2 cups
- 2 teaspoons of salt
- 2 teaspoons of sugar
- 2 teaspoons of honey
- A spoon
- A stopwatch
- Paper and pencil/pen for results
- Your positive attitude
Instructions:
1. Choose your first solute to dissolve and bring your 2 cups
2. Fill 1 cup with warm water and the other with cold water. These will be your solvents.
3. Add one teaspoon to the warm water and start your stopwatch to time how long it will take to dissolve.
4. Write down your results on your paper
5. Add your other teaspoon to the cold water and start your stopwatch to time how long it will take to dissolve.
6. Write down your results on your paper.
7. Compare your warm water results with your cold water results. What do you notice?
8. Repeat the steps above for the other solutes and refill your cups with new water.
Part 2: Summarize your results in a paragraph and create a page of information about solubility, solutes, and solvents using the research links provided below. Cover all basic information.
Focuses:
1. What are they?
2. What happens when they come together
3. What are some examples of solutes and solvents making a solution in the real world
4. Types of solutes and solvents in the real world
5. What molarity, molality, and mass percent has to do with solutions

Task #2
Part 1: Research what pure substances and mixtures are and what makes them different and similar. You have to find out the connections between mixtures and solutions and some methods to separate them in the real world. Write your research in notes so it would be easier for you to study them for the quiz.
Focuses:
1.What pure substances and mixtures are
2. Heterogeneous and homogeneous mixtures
3. Examples of mixtures
4. Methods of separating mixtures
5. Examples of pure substances and mixtures in the real world.

Part 2: After you complete the basic research, take all of your information about the pure substances and mixtures and put it in a Venn diagram organizing all of the information about the similarities and differences into one neat diagram. Make sure to include all of the key information in the Venn diagram as it will help you understand this topic.
You can use the two Venn diagram makers below:

Part 3:
a) Study the particle theory and its properties. Focus on the questions below.
Focuses:
1. What is it
2. Who created it and why
3. What are the 5 components of the particle theory
4. What does it explain
5. Any other information you can find (ex. why is it important, more details etc.)

b) Based off what you researched, create a small model of a particle formation following the components of the theory. It could be solid, liquid or gas.

Task #3
Part 1
For your 3rd activity, you will have to conduct a second experiment, which will be teaching you about concentration in a saturated solution. This will take you further into what it really is. Make sure you conduct this experiment with all the materials and following all the instructions.
Materials you need:
- Table salt
- Water
- Heating device to evaporate
- 2 containers
- Balance
-Paper and pencil/pen
Instructions:
1. Get a small amount of water for your experiment and out it into one of the containers.
2. Add a tablespoon of salt to the water and stir until most is dissolved and some is left over at the bottom
3. Take your other empty container for evaporating and weigh it on the balance
4. Carefully, pour all of the water into the container, leaving all of the excess salt behind
5. Evaporate all of the water out of the container to leave only some of the excess salt we have missed in step 2
6. Gather all of the remaining salt and weigh it
7. Write down your results.
The experiment has shown you saturation, and what you have learned before, the separation of substances from a solution, which in this case would be evaporation.
Part 2 :
With the links below, research more about concentration levels of solutions or maybe more about saturation if you want. With this information, you will create your own experiment to conduct with others, basically teaching some of the things you learned to them.

Make sure to study all of the information you have gathered. We suggest you highlight key points and study those and focus on all the details later.
