Germ and Hand Washing Experiment for Kids

It is important for kids (and adults) to wash their hands frequently to prevent spreading germs. But many kids are reluctant to do so as frequently as they need to. I’ve found that showing kids WHY they need to wash their hands is the best way to encourage hand washing! This hand washing experiment is quick, easy, and effective at teaching kids to use soap and water to stay healthy. Perhaps you’ve seen the hand washing experiment with pepper, well this¬†germ experiment for kids uses glitter! Youv’e got to try this¬†hand washign science experiment¬†for toddler, preschool, pre-k, kindergarten, first grade, 2nd grade, and 3rd graders too.

Germ Experiment for Kids

Did you wash your hands? Did you use soap? These are common questions heard by kids of all ages at home from their parents and at school in the classroom. We know that washing your hands with soap and water prevents the spread of germs and helps us stay healthy. But teaching kids the importance of these good hygience practices can take some coaxing. This germ experiment for kids allows toddlers, preschoolers, kindergartners, grade 1, grade 2, and grade 3 students to understand how germs spread and how washing hands with soap and water keeps them safe. Try this germs and soap experiment with just a few simple materials you probably alreayd have on hand.

Hand Washing Experiment

There are lots of germ experiments for kids to demonstrated the concept, but we decided using glitter was a great visual! All you need to try this kids germ experiment are a few simple materials:

  • hand lotion
  • orange glitter
  • purple glitter
  • blue glitter
  • baby wipes
  • soap and water

Germs Experiment for Preschoolers

Start out with clean hands. No put a little bit of lotion or hand cream on every participant. You can do this with just 2 people, 3 people like we did, or have the whole class involved.

Germ Experiments for Kids

Sprinkle kids hands with a little bit of glitter. We used a different color for all three participants so you can see how germs spread.

Ask children what they thing will happen? Will the glitter germs spread?

Hand Washing Science Experiment

Have children shake hands with one another as they usually would. For this demonstartion we limited to hands as my goal was to teach kids the importance of washing their hands. But you could show kids how the glitter germs could end up on sleeves, shoulders, faces, etc. GERMS SPREAD!

staying healthy for kids

Now have students look at their hands. THe glitter germs have spread. Most kids will have a combination of all colors of glitter germs.

HINT: If yo uused yellow and blue it may start to look like green. You can use this as a chance to teach them how germs can combine to form a new strand or mutant germ that can be harder to eliminate.

good hygiene lesson for preschoolers and kindergartners

Ask students how they clean their hands. If they are honest, kids will give a variety of answers like wipe them on their pants, wash with water only, wipe with a baby wipe, etc.  have children make a hypothesis (great way to teach abou the scientific method) if the baby wipe will eliminate the germs.

Now give each student a wipe. While it did remove some of the glitter and makes our hands look cleaner, it did NOT get rid of all the germs.

Germs Experiment for Preschoolers

Germs and soap experiment

Ask students how they should clean their hands to get rid of the germs. The correct answer is by washing with SOAP and WATER for at least 20 seconds.
