Conclusion :Label paper cups: R and B for red and blue. Mark a line about 1/3 of the way from bottomPut 1 level tsp of each mix in your cups. Test the aroma (use correct technique) and appearance of each. Record ratings.Use the toothpick to taste each dry mix. Record ratings.Mix with water: Recipe Don't mix up the spoons.1 level tsp. powder + 1/3 of the small cup of warm
water. STIR WITH TOOTHPICK!!
Analysis of cocoa lab
1. The experimental variable is __________
2. Variables we Made the Test
Controlled: Unfair:
3. The thing about this experiment is.... (THE COCOA EXP!)
4. The cocoa experiment was not a valid "scientific" experiment because the variables were not controlled.TRUE OR FALSE. EXPLAIN
5. How could bias
influence the outcome of
the cocoa lab?

If all matter is made of molecules, what makes solids melt and liquids freeze?
Use the top half of the page to respond to this question- use words and pictures to show me what you know.
Atoms in Solids (P 54)
Atoms in Liquids (P 54)
Atoms in Gases (P 54)
In each box, include two facts and a picture
Use the top half of the page to respond to this question again- use words and pictures to show me what you know, and what you learned throughout the unit.
.Look back at your notebook pages (17- 29) for ideas of what to write and draw.

Problem: How does the volume of matter change if pressure is increased?Info we have: Particle theory of mattersolid liquid
gas
Hypothesis: Look at your pictures above: What will happen to the volume of each as books are piled on (give % eg 100%, 0%, 50%, ? Give a reason for each.
Gas (air): The volume will be ____ %
because____
Liquid (water): The volume will be ____ %
because____
Solid (ice): The volume will be ____ %

Ice and salt Line
Why does adding salt to ice make it colder?
The melting/ freezing point of water is _____ ˚C.
By adding salt to ice it ____________ the melting/ freezing point to _________˚C.
Heat energy is needed to change _____________ ice to ______________ water because…..
Discussion Questions:
12345
Temp.
Time
Predict how the temperature will change as your ice melts. Add a line to predict what the temperature will do when you add salt.
It’s Freezing!!!1. Problem: What is the freezing/ melting point of water?
How will adding salt change the temperature of ice?
2. Find definitions for Melting/freezing point:
3. What does temperature tell us about the motion of molecules?
4. Information: We used salt in making the ice cream We use salt on roads to
melt ice.
Hypothesis: I think that adding salt to ice will make the temperature……… BECAUSE……..
Ice Only Ice + Salt

Data Analysis
Questions from handout1. What happened after you added the salt to the ice? Was the temperature above or below the ice only?2. What is the only factor that could have caused the changes shown in question 1? What does this tell you about the freezing point temperature of salt water compared to fresh water?
Use page 260 to give explanation.3. Heat energy is needed to change phase from a solid to a liquid. List the possible sources of the heat needed for this phase change in your beaker.
Use page 260 to give explanation.4. Explain how we could use the information we found outabout temperature changes in salt water in this experiment to make ice cream.5. In the radiator of your car you put a combination of antifreeze and water to keep your car engine cool in the summer and prevent the radiator from freezing in the winter. Explain how you think this works in terms of what you saw in the experiment you just did.
Use page 261 to give explanation.
