New materials often involve chemical reactions, and slime is no exception. In this lesson, students will use the engineering design process to design a slime product. They will need to decide on the desired properties for their slime and then experiment to find the best recipe.

Prep Work

Preparations: Place all the materials students will use to make their slime on a table that is easily accessible for students.

If the Explore section cannot be completed in one lesson, take a break after the background research is completed (13:40 in the Whole Lesson video, or 8:18 in the Explore video). Make sure the students describe the properties of the basic slime they created before taking a break as the slime might change and become more rubbery overnight.
