Making slime is an activity that almost every child, young and old, will enjoy. Today, we are going to not only teach you how you can make slime with your little one, but also explain some of the science behind what’s going on. After all, that is what makes it a STEM (science, technology, engineering, and math) activity.

How to Make Slime

Making slime is super simple and only requires a few ingredients, and you’ll most likely have most of these around the house already. For this recipe, you can add a few drops of food coloring to make the slime match your child’s favorite color or begin with a colored washable school glue. 

Ingredients: 

  • 5 oz of school glue such as Elmer’s
  • ½ Tbsp of baking soda
  • 1 Tbsp of contact solution
  • Food coloring (optional)

Instructions:

  1. Pour all of the glue into a bowl.
  2. Add your baking soda and mix thoroughly.
  3. Next, add the contact lens solution and begin mixing.
  4. Remove the slime from the bowl and continue to knead it until it reaches the desired consistency.
  5. If it’s too sticky, add an additional ¼ Tbsp of contact solution. 

What Is the Science Behind Slime?

Slime allows us to explore the way polymers and Newtonian fluids behave and how they can bond together to become a non-Newtonian fluid. This may seem a bit of an in-depth explanation for a preschooler, so it can also be explained in terms of liquids, solids, and how slime is actually neither. Viscosity is also another property that slime allows us to explore. 

One of the most fun aspects of making slime to explain to your children no matter their age is the chemical reaction that occurs when the ingredients are added together. When making slime, you’ll likely notice that it becomes cold. This is due to an endothermic reaction that occurs when the polymer (the glue) combines with the activator (contact lens solution). 

One of the benefits of making slime as a STEM activity is that as your children get older, or if you have children of different ages, they can enjoy making slime and learn about the scientific principles that are age appropriate for them.
