A hands-on lab activity with slime!
? 5 fl. oz. Elmer’s Translucent Color Glue
? ? tbsp. baking soda
? 1 tbsp. contact lens solution
? Mixing utensils
? Measuring spoons
? Cotton balls
? Kinetic Sand??
?Kinetic Sand? is a registered trademark of Spin Master Ltd.
- Pour the entire bottle of Elmer’s? Translucent Color Glue into the bowl.
- Add ? tbsp. of baking soda and mix thoroughly. Add 1 tbsp. of contact lens solution and mix until solution gets thick and slime begins to form.
- Take out the slime and begin kneading it with both hands. If needed, add another ? tbsp. of contact lens solution to make the slime less sticky.
- Now put on your lab jackets, and let’s get science-y. Divide your slime into three sections of equal size.
- Ask students questions: What do you think will happen to your slime if you add cornstarch, sand, or cotton to it? Have them write out a hypothesis. Then have them add cotton balls to one ball of slime, Kinetic Sand? to another, and cornstarch to the third.
- Were the hypotheses correct? Why or why not? Have each student or group of students report their findings to the class.
