This activity combines science and art to provide an understanding about why the sea is salty. Students will obseve how salt concentration increases in water and how the salt remains after the water evaporates. They will do a salt painting using water, salt, and food coloring to observe the evaporation process.

This experiment teaches students about the effects of acid rain on rock, buildings, and sculptures. They will use chalk and vinegar solution to demonstrate the chemical reaction of acid on limestone and explain what happens in this process. They will also identify the compounds used in the reaction, the gas which is given off, and learn about the sources of acid rain.

This experiment is designed to allow students to observe and understand chemical and physical weathering of simulated "rocks". They will place the materials in plastic bags, one wet and one dry, and store them for 3-4 days. At the end of the storage period, they will observe the contents of both bags and answer some questions about what they see.
