STEM Activity: DIY Toothpaste Experiment

In honor of Children’s Dental Health Month, we at Little Medical School are excited to share an engaging and educational STEM activity. This hands-on experiment will teach kids about dental health and the science behind toothpaste: The DIY Toothpaste Experiment!

DIY Toothpaste Experiment

The DIY Toothpaste Experiment is a fun way for children to learn about the ingredients in toothpaste and their role in protecting our teeth.

 

Materials Needed:

  • 2 tablespoons of baking soda
  • 4 teaspoons of glycerin
  • 1/2 teaspoon of salt
  • Flavoring (like peppermint or vanilla extract)

Steps to Conduct Your DIY Toothpaste Experiment:

 

  1. Mix the Ingredients: In a bowl, have your child mix the baking soda and salt. Then add the glycerin and a few drops of flavoring. Stir until it forms a paste. 
  2. Test the Toothpaste: Let your child try brushing their teeth with the homemade toothpaste. Discuss how it feels, tastes, and works compared to regular toothpaste. 
  3. Discuss the Science: Talk about how each ingredient helps clean and protect our teeth. Baking soda and salt act as mild abrasives that clean the teeth, while glycerin gives the paste its texture. 

Learning Opportunities:

This interactive experiment offers several educational benefits:

 

  • Understanding Chemistry: Children learn about the role of different ingredients in toothpaste and how they work together to keep our teeth clean. 
  • Promoting Dental Health: This activity emphasizes the importance of brushing our teeth regularly to maintain good oral health. 
  • Inspiring Future Careers: Activities like this can inspire children to explore potential careers in fields such as chemistry, dentistry, or product development. 

Remember, safety first! Always supervise your children during STEM activities.

 

Join us at Little Medical School, where we make learning fun and engaging while inspiring the next generation of healthcare professionals. Enjoy conducting your DIY Toothpaste Experiment!
