5 HANDS-ON ACTIVITIES ABOUT TEACHING GERMS TO KIDS

Find engaging and engaging ways to teach children about germs and maintaining good health! This blog examines easy science experiments, hands-on exercises, and interesting reading lessons that teach kids about the spread of germs and the value of cleanliness. These activities, which range from germ-themed crafts to hand washing experiments, make learning engaging and educational.

Easy-to-follow lesson plans that emphasize vocabulary, understanding, and important hygiene behaviors are available for both parents and teachers. Let's explore creative solutions to make germ education enjoyable and meaningful for children!

1. Glitter Germs: A Hands-On Lesson in Spreading Germs

Since germs are invisible to the human eye, teaching children about them can be challenging. A simple yet effective method of teaching kids about the transmission of germs and the importance of handwashing is the Glitter Germs experiment. Children can observe how readily germs spread from one surface to another and how challenging it is to get rid of them without soap and water by using glitter as a metaphor for germs.

How It Works:
To begin, apply a small amount of lotion to each child’s hands. This will help the glitter stick, just like germs cling to our skin. Have them shake hands, touch desks, and give each other high fives after you've sprinkled glitter over their palms. They'll notice the glitter all over in a matter of seconds! This is an example of how germs spread by touch, moving from one person to somebody else and onto other surfaces without us even realizing it.

Ask kids to try using a dry paper towel to wipe off the glitter because this is an essential step in eliminating the "germs." It won't come off all the way! After that, rinse them with water alone. Most of the glitter will still be present. Lastly, ask them to wash their hands with water and soap.

Children learn from this practice that germs are spread by touch and cannot be eliminated by just washing their hands or rinsing them with water. Water and soap are necessary for good hand washing and keeping off germs!

Pro Tip: Use different colored glitter to symbolize different kinds of germs to make the lesson even more captivating. For instance, blue glitter might stand for viruses, and red glitter for bacteria. After the activity, you can ask students to look at typical items in the classroom, such as chairs, pencils, or door handles, to determine how much "glitter germs" have spread.

2. Grow Your Own Germs: A Science Experiment

Children can be effectively taught how many germs are hidden on their hands and common surfaces with this interactive science project. Children frequently aren't aware of how easily germs can spread because they are invisible to the human sight. Students can observe firsthand the effects of good handwashing and the invisible world of mold and bacteria by using slices of bread to "grow" germs.

How It Works:
Because bread is wet and nutrient-rich, it is a perfect place for mold and germs to grow. Students can see the shift in germ growth over time by touching bread slices with clean and dirty hands. The "Doorknob" test, which is optional, further emphasizes how often touched surfaces can harbor and spread germs.

Students will observe that mold grows on bread touched by unwashed hands far more quickly than it does on the clean sample as the days go by. They are able to understand the need of hand washing with soap and water for maintaining good health thanks to this visual illustration.

Pro Tip: Make a class observation chart and take pictures of the bread every day. Students can use this to monitor the mold growth and have scientific conversations about their findings. Asking kids to investigate the various kinds of germs and mold that could be developing on the bread is another way to extend the lesson!

3. Germ Detectives: The Blacklight Hand Washing Challenge

Students frequently believe that washing their hands under water is enough, yet germs can hide in locations that we aren't always aware of. Students may observe firsthand how germs remain on their hands even after washing them with the fun and informative Blacklight Hand Washing Challenge! In addition to teaching children how to properly wash their hands, this engaging exercise also makes them more aware of their personal hygiene practices.

How It Works:
Students will visually monitor how effectively they wash their hands by using baby powder to represent pretend germs. Similar to actual germs, baby powder sticks to the skin. When it is subjected to a blacklight, the microscopic particles glow, exposing areas that are neglected, such as the nails, fingertips, and spaces between fingers. Students examine their hands again under the blacklight after their initial wash to make sure they have completely cleaned them. Through this experiment, students may transform a basic hygiene lesson into an engaging detective quest to find out how well they actually wash their hands!

By bringing the invisible world of germs to light, this interactive experiment engages children. It teaches kids that washing their hands properly involves more than just rinsing them. It involves scrubbing every area of their hands for at least 20 seconds.

Pro Tip: Try using lotion mixed with a small amount of baby powder to better simulate how germs stick to the skin. This makes the blacklight reveal even more dramatic and emphasizes the importance of using soap and friction to get truly clean hands!

4. Storytime Connection: Germs in Books

Pair your science lessons with a fun read-aloud! Try this book I highly recommend:

GERMS Science Activities Kindergarten and First Grade - Germs! Germs! Germs!
Make learning about germs and staying healthy exciting with these hands-on science and reading activities! Students will explore good and bad germs, bacteria, and viruses through interactive experiments, handwashing demonstrations, vocabulary-building exercises, germ-themed crafts, and daily writing activities. This comprehensive resource includes differentiated lesson plans and engaging STEAM activities that align with the book GERMS! GERMS! GERMS! by Bobbie Katz.

This week-long unit is designed to give teachers and students a structured, engaging way to explore children's literature while strengthening vocabulary, comprehension, higher-level thinking, and ELA-based skills.

5. Healthy Habits Game: Germ-Free Classroom Challenge

Making the lesson engaging and interactive is essential when teaching children about germs. By transforming healthy practices into an engaging game, the Germ-Free Classroom Challenge motivates children to maintain good hygiene while earning points and prizes. This task fosters responsibility and teamwork in the classroom in addition to reinforcing the value of maintaining hygiene.

How It Works:
Create a chart in the classroom so that children may monitor their weekly healthy behavior. Students receive points for adhering to the hygiene guidelines, which include washing their hands before eating, covering their coughs and sneezes, using tissues appropriately, and refraining from touching their faces. You can make a basic tally system or give each behavior a separate value.

Since repetition helps kids develop healthy routines that last a lifetime, this promotes everyday hygienic practices. Create some friendly competition by assigning students to teams or establishing a class-wide goal to keep them interested. Celebrate their successes at the conclusion of the week by giving them a fun reward, such as extra recess, a classroom certificate, or a simple prize like stickers.

Pro Tip: Use a secret reward system where kids don't know their prize until the end of the week to add even more excitement. This maintains a high level of engagement and promotes regular participation! To honor kids that go above and above in maintaining proper hygiene, you can also designate a "Germ-Free Champion" of the week.

Healthy Habits to Keep Kids from Getting Sick

1. Handwashing: The Superpower Against Germs

One of the best ways to prevent illness is proper handwashing. Teach kids to wash their hands:

Before eating
After using the restroom
After coughing, sneezing, or blowing their nose
After playing outside or touching shared surfaces
Use a timer, sing "Happy Birthday" twice, or use color-changing soap to encourage proper handwashing.

2. Covering Coughs and Sneezes the Right Way

Germs spread easily through the air when we cough or sneeze. Teach kids to:

Cough or sneeze into their elbow
Use a tissue and throw it away immediately.
Wash hands after sneezing or coughing
Turning this into a game, like a "sneeze and cover" challenge, helps reinforce the habit!

3. Keeping Hands Away from the Face

Kids often touch their faces without thinking, which can spread germs from their hands to their eyes, nose, and mouth. Teach them to keep their hands busy with fidget toys, activities, or simple reminders like a "no-touch" challenge.

4. Eating Nutritious Foods for a Strong Immune System

A balanced diet full of fruits, vegetables, whole grains, and proteins helps keep the immune system strong. Tell kids to eat "rainbow foods" by picking colorful fruits and veggies like carrots, berries, and spinach. Hydration is also key in which water is the best choice!

Create a healthy eating chart where kids earn stickers for trying new fruits and veggies.

5. Getting Enough Sleep for a Healthy Body

Sleep is crucial for staying healthy. Kids need around 10-13 hours for preschoolers and around 9-12 hours for school-age children.

Help kids apply bedtime routines like reading a book, dimming the lights, and avoiding screens an hour before bed.

6. Keeping Things Clean: Germ-Free Spaces

Regularly cleaning commonly touched items like toys, doorknobs, and school supplies reduces the spread of germs. Make cleaning fun by turning it into a quick “germ-busting” game!

Encourage kids to:
Wipe down their desks or lunch boxes
Keep personal items separate (E.g. No sharing of water bottles!)
Put dirty clothes in the laundry after school or outdoor play

7. Staying Active for a Strong Body

Exercise helps boost the immune system and keeps kids strong. Whether it’s running, biking, playing tag, or doing fun movement games indoors, staying active is a great way to stay healthy.

Set up a fun daily fitness challenge, like "10 jumping jacks before dinner" or a "family dance-off."


Teaching kids about germs doesn’t have to be boring. It can be a hands-on adventure into the unseen world! Letting them know about these simple healthy habits helps them stay well and reduces sick days. By making hygiene, nutrition, and exercise fun, kids are more likely to build lifelong habits that keep them healthy.

By using engaging activities, science experiments, and storytelling, you can help children understand how to stay healthy while having fun in the classroom.
