Name: The Melt Down
Purpose: Try to keep ice from melting in the hot sun.
different colored construction paper
Rocks to hold things down
Lay out the paper towels, one in the shade and the rest in a row. Cut up the construction paper into small squares just bigger than the ice cube. Take the three cups and label them soda, water, and rubbing alcohol with the masking tape and pencil. Fill the cups with the appropriate liquid. Spread the construction paper over the paper towels. Put some baking soda in a Ziploc bag. Place rocks on anything that may blow away in the wind. Put one ice cube in the Ziploc bag and shake it around, making sure it is coated with the baking soda. Sprinkle salt on another ice cube away from the paper towels. Place them on the paper towel a couple inches away from each other. Working quickly, put an ice cube on each different colored paper, in each of the cups, on in the shade, on in the box. Then place one on just the paper towel, this is your control.
