Chemistry Unit 3 - Week of April 20-24
- You will test salt water, soapy water, vinegar, and vinegar with salt to see which ones will clean the tarnish off a penny (a pre-1982 penny). Then, when one penny changes from dark and dirty to bright and shiny, you’ll have a chance to think about where the tarnish went. Soak the pennies overnight with a nail to see if you are right.
- You will use one of the solutions from part 1 and several pennies to copper plate a steel nail. You will then create a written model of how the particles in the experiment move.

- Obtain two clear cups.
- Place a small piece of carrot (about 2in.) into the first cup. Note that it sinks.
- Add salt, one spoonful at a time, to the cup of water and stir it until it dissolves.
- Record how many spoonfuls it took before the carrot floated.
- Place a small piece of potato (about the same size as the carrot) into the second cup.
- Repeat steps 3 and 4 for the potato.
- Which object, the carrot or potato, required the most amount of salt to float? What was happening as the salt was added to the water? (Hint: it has to do with density).
- If you were swimming, would it be easier to stay afloat in a lake or in the ocean? Why?
- Which is more dense, salt water or fresh water?
- TedEd - How do ocean currents work?
