It's gooey. It's sticky. It's slime! Learn to make your own homemade slime with this quick and easy recipe.
There are many different ways to make slime. In this lesson plan, your students will use the engineering design process to design their own slime product. They will need to decide on the desired properties for their slime and then experiment to find the best recipe.
NGSS Performance Expectations:
Define a simple design problem reflecting a need or a want that includes specified criteria for success and constraints on materials, time, or cost.
Conduct an investigation to determine whether the mixing of two or more substances results in new substances.
- Optional: 5-PS1-2.
Measure and graph quantities to provide evidence that regardless of the type of change that occurs when heating, cooling, or mixing substances, the total weight of matter is conserved. (see Variations)
Science Fair Project Idea
Have you ever wondered how fun toys like Silly Putty®, Gak™, and Slime™ are made? These products are so much fun because of the properties of polymers, which make them delightfully bouncy, stretchy, sticky, moldable, breakable, hard, soft, and just plain fun! In this science project you can be the developer of your own slime product by changing the amount of a key ingredient. By observing the physical properties of your results, you can choose the best recipe for your new…
Science Fair Project Idea
There are many different kinds of slime out there. Some slime is runny and liquid-like; other slime is thick and rubbery. Some slime glows in the dark, some is fluffy, and some is even magnetic! What set of properties makes the best slime? What kind of slime would you choose to make if you were selling slime as a toy in your own "slime shop"? In this project, you will experiment with different slime recipes and try to perfect one to make the best slime.
A team of PPG volunteers got hands-on with homemade slime! The team applied their science expertise to the process of making slime and tested directions and variations for student and educator use.
Above: PPG employees put the Slime Chemistry student science project to a hands-on test to find ways to make the popular project even more fun and rewarding as a STEM learning activity.
A Commitment to Student STEM Education
For the last several years, PPG's…
