10+ Germ Activities for Kids

So, let’s explore some fun and practical ways to teach your students about germs:

1. Glitter Germ Simulation

When it comes to teaching young students about how easily germs spread, nothing beats the classic glitter germ experiment. This is one of the most visual and memorable germ activities for kids, because it shows — right in front of their eyes — how germs move from one person to another through touch, even when they don’t realize it.

Materials Needed:

  • Glitter (fine, loose type)Hand lotion or liquid hand sanitizer
  • Soap and warm water
  • Towels

How to Do:

  • Give each student a small dab of lotion or hand sanitizer and sprinkle some glitter on top.
  • Let the students shake hands, touch objects, and interact as normal.
  • After a few minutes, pause the activity and have students observe how the “glitter germs” have spread across their hands and the classroom.
  • Take them to wash their hands and compare results before and after proper handwashing, emphasizing the importance of using both soap and water.

2. Glo Germ Experiment

The Glo Germ Experiment allows kids to physically see the invisible. Using a special product called Glo Germ, students will apply simulated germs to their hands and attempt to wash them away.

Under UV light, students will be surprised at how much “germ residue” is left, teaching them that fast or lazy washing isn’t enough to stay clean and healthy.

  • UV blacklight flashlight
  • Soap and warm water
  • Paper towels

How to Do:

  • Apply Glo Germ to each student’s hands, making sure it covers all areas.
  • Let them wash their hands as they normally would, using soap and water.
  • Use the UV flashlight to check how much of the Glo Germ remains on their hands.
  • Discuss the importance of washing all parts of the hands for at least 20 seconds and retry the process to reinforce good habits.

3. Handwashing Song Challenge

Many kids rush through handwashing, often spending less than five seconds at the sink. This musical challenge turns a simple routine into a fun and memorable habit. Singing a favorite tune while washing helps children slow down, scrub thoroughly, and enjoy the process — making clean hands something they actually look forward to.

Materials Needed:

  • A list of handwashing songs (e.g., “Happy Birthday” twice or “ABC Song”)
  • Soap and water
  • Posters with song lyrics (optional)

How to Do:

  • Teach students a song that takes about 20 seconds to sing from start to finish.
  • Encourage them to sing or hum the song while washing their hands, making sure to clean between fingers, under nails, and the back of hands.
  • Reward students who follow through with a clean-hands check after each bathroom break or before meals.

4. Lotion and Pepper Germ Demo

If you’re looking for a simple and science-backed activity for kids , this pepper demo offers a fantastic visual of how soap repels germs. Students watch as “germs” (pepper flakes) scatter the moment a drop of soap touches the water — a clear reminder that washing with just water isn’t enough.

Materials Needed:

  • Plate or shallow bowl
  • Water
  • Ground black pepper
  • Dish soap

How to Do:

  • Fill the dish with water and sprinkle pepper over the surface to represent germs.
  • Have students dip a clean finger into the water and observe what happens (usually nothing).Place a drop of dish soap on the tip of their finger, then dip it back in — the pepper will rapidly scatter away from the soapy finger.
  • Discuss why soap helps break apart and wash away germs from our hands.

5. Grow Your Own Germs (Petri Dish Experiment)

This activity is a perfect mix of real-world science, giving kids the chance to explore their surroundings and discover where germs like to hide. Watching bacteria colonies grow in petri dishes is both fascinating and a bit gross — making it an exciting experience for curious young minds.

Materials Needed:

  • Petri dishes with agar
  • Sterile cotton swab
  • Permanent markers
  • Clear tape

How to Do:

  • Give each student a swab and ask them to sample different classroom surfaces — desks, doorknobs, light switches, and hands.
  • Swipe the swab onto the agar inside a labeled petri dish.Seal the dish with tape and leave it in a warm, undisturbed area.
  • Check the dishes each day and let students observe germ colony growth over time.

6. Handprint Germ Arts

These hands-on crafts offer creative activities for kids to understand how germs work. By using paint to mimic the invisible dirt on their hands, students can visualize how unclean hands might appear under a microscope. It also sparks important conversations about when and why handwashing is crucial, especially before eating or after playing outside.

Materials Needed:

  • Washable tempera paint
  • Large sheets of paper
  • Markers or crayons
  • Soap and water for cleanup

How to Do:

  • Have each child dip their unwashed hands lightly into paint and press them onto a piece of paper to make a “germ handprint.”
  • Once dry, ask students to use markers to draw what kinds of germs they think might be hiding on their hands (viruses, bacteria, etc).
  • Discuss why germs are invisible in real life, and when handwashing is most important to prevent spreading them.
  • Wash hands thoroughly after the activity and reflect on the difference between “dirty” and “clean.”

7. Germ Spread Graphing

One of the most impactful germ lessons and activities for kids is helping them see how far and wide germs can travel when someone sneezes. Using a spray bottle as a stand-in for a human sneeze gives students a realistic view of how germs spread and highlights the importance of covering your mouth and nose.
