density identities
enrichment activity for lesson 2-1
skills: interpreting a table, applying
the table below its the densities of common substances. an object with a lower
density roots in a liquid or gas that has a higher density. use this idea and the
table below to name the substances described.

1. i am a liquid. if you mix me with water, i foat on top, but if you mix me with gasoline, i sink. what
am i?
2. i am a l-cm cube. my mass is just 0.10 g less than the mass of a l-cm cube of iron. what am i?
3. although i am a solid, i am so light that i can float in any liquid listed on the chart. what am i?
4. in a liquid mixture with water and corn syrup. i'll always be in the middle. what am i?
5. i am a solid. i float in water, but not in alcohol. what am i?
6. an object made of me is light enough to float in corn syrup, but not in water. what am i?
7. my density is one. what am i?
8. although we are not related, 1 kg of me will take up the same space as 1 kg of aluminum. what am i?
