Rain, Rain -- Go Away is a science project that teaches kids about the effects of acid rain. Sometimes chemicals get in the air and mix with water to form "acid rain."
What You'll Need:
- Two jars
Learn about Rain, Rain -- Go Away:
Step 1: Put 1/4 cup of water in one of the jars. Ask an adult to cut two small squares of sod from your lawn or buy some sod at a nursery. Push one square of sod down into a jar so that the sod's soil is in the water.
Step 2: Then put 1/4 cup of vinegar in the other jar. Push the second square of sod down into the jar, so the soil is in the vinegar.
Step 3: Now place both jars in a warm, sunny place, and watch what happens over the next several days.
Step 4: Vinegar is an acid, like the acid in acid rain. Acid rain is a worldwide problem. It can be caused by smoke from factories, burning coal, and even car exhaust. In addition to harming plants, acid rain also pollutes bodies of water, kills fish, and destroys rocks and buildings!
Why is the sky blue? The science project for kids called Blue Skies uses visual aides to explain this natural phenomenon. Read about it on the next page of science projects for kids: weather and seasons.
