3. Conclusion : Label paper cups: R and B for red and blue. Mark a line about 1/3 of the way from bottom Put 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!!

Info we have: Particle theory of matter solid 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 ____ % because____ • 30 Conclusion: • The gas (could or could not) be compressed more because..... • The liquid (could or could not) be compressed more because..... • The solid (could or could not) be compressed more because..... • Conclusion: • The most surprising conclusion from this experiment was… Look at your hypothesis!

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 Line 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: 1 2 3 4 5 Predict how the temperature will change as your ice melts. Add a line to predict what the temperature will do when you add salt. Data Analysis See next page for questions 34 35

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…….. • Questions from handout • 1. 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 out • about 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. Predict how the temperature will change as your ice melts. Add a line to predict what the temperature will do when you add salt. Data Analysis 34 35
