Germ Science Experiment - Handwashing Activity

Teaching children to wash their hands is crucial! Kids often seem a little reluctant to wash their hands and if they do wash them it is often a quick rinse under the tap. With this Germ Science Experiment you can demonstrate to young children the importance of using soap when washing their hands to keep the germs away.  This hand washing activity is not only fun, but a great way to teach kids about germs.

STEP 3: Demonstrate how soap removes the germs right away

Squirt a small amount of soap onto your child's finger and then put it into the water. Here is when you show your kid what happens next!

The soap makes the germs run away! The pepper immediately scatters when it comes into contact with the soap.

This experiment is actually demonstrating how water surface tension works, but it's a great way of demonstrating to young children in a visual way why we need to use soap when washing our hands.

After doing this germ science experiment complete this hand washing activity by showing children how to wash their hands with soap for 20 seconds before rinsing the soap off (we don't want them thinking just dipping their finger into soap will keep the germs away!)

The kids will love this hand washing activity. The reaction is fast and it's a fun way to learn about germs. I hope you and your children enjoy trying out this germ science experiment!
