7. What are the differences between Coke & Diet Coke that might account for your results?

8. How can you determine what will sink and what will float?

9. Why does one float and the other sinks? 50,000,000g 10,000,000mL 3g 30mL Sinks Floats

10. Why does one float and the other sinks? 50g 40mL 626g 7,825mL Sinks Floats

12. Why do both float when they are different sizes? 62.5g 125mL 125g 250mL Floats

13. Density The measure of how tightly packed the molecules of a substance are. Density = Mass / Volume Density = g/mL Each pure substance has characteristic physical properties that can be used to identify it. Density is one of these properties.

14. What microscopic pattern(s) do you notice about what sinks and what floats in water? Sinks Floats 5g/mL 20g/mL 1.25g/mL 0.5g/mL 0.1g/mL 0.08g/mL 0.02g/mL

15. Density of Water 1g/mL 1g/cm 3

16. Write a statement about the microscopic patterns you observed about what floats or sinks in water. Sinks Floats 5g/mL 20g/mL 1.25g/mL 0.5g/mL 0.1g/mL 0.08g/mL 0.02g/mL

17. Explain : What could be changed to make the Coke float? (without opening the can) Explain why this would work.

18. Making a Density Column to Determine Relative Density Relative Density the density of a substance in relation to another Create a density column that has all 3 liquids and colors. Illustrate your results.

19. Making a Density Column to Determine Relative Density Questions: Which substance is the most dense? Which substance is less dense than the other two? Create a 2 dimensional model of your density column that explains the unobservable reason for the color separation. (Hint: How can you illustrate density?)

20. Phenomenon Ice floats in water. Why does the ice in a glass of ice water float? Read your initial answer to this question. Revise your answer and add an illustration that supports your answer.

21. Homework 1.)Explain why the two cubes have the same density even though they have different volume and mass. 2.) Can two substances with different density be made of identical material? 100g 5mL 500g 25mL
