Sid the Science Kid: The Big Sneeze
Sid’s parents tell him to wash his hands to keep away germs. But Sid can’t see any germs on his hands, so why should he wash them? Sid and his friends learn that germs are so small that you can’t see them. And they discover that a great way to stay healthy and keep germs away is by washing their hands with soap and water!
Clean It Up!
Materials: potting soil in a large container, paper towels, soap and water for washing hands, magnifying glass
Procedure: 1. Have children dig into the soil and really get their hands dirty
2. Then use paper towels to try and wipe the dirt away. Did it work? Are your hands still dirty? Use the magnifying glass and have children look at fingernails and other areas that dirt gets trapped. Have children describe what they are seeing.
3. Dig into the dirt again. Now try to remove the dirt using soap and warm water. Have them observe their hands again. Did the soap and water clean your hands better? If there’s still some dirt, have children wash their hands again, paying special attention to the dirty places.
