Everyone enjoys making slime!!! Slime is an easy and fun way to teach about polymers and cross linking. This slime kit contains one liter of colorless, 4% polyvinyl alcohol - initially clear, but it can easily be colored using food dyes - and enough sodium tetraborate solution to cross-link with it. A preservative has been added to avoid the growth of unwanted creatures. Investigate a cross-linked polymer. If pulled slowly, it flows; if pulled quickly, it breaks; and if rolled into a ball, it bounces.
Enough for more than 60 students to make a 1/2 ounce portion (~15 cc).

This product will support your students' understanding of the Next Generation Science Standards (NGSS)*, as shown in the table below.
|
Elementary
|
|
Middle School

High School
|
|
2-PS1-1
Students can use the Classroom Slime Kit to plan and conduct investigations to describe and classify kinds of materials by their observable properties.
5-PS1-3
Students can use the Classroom Slime Kit to make observations and measurements to identify materials based on their properties. |
|
MS-PS1-2
Students can use the Classroom Slime Kit to analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.
MS-PS1-5
Students can use the Classroom Slime Kit as a model to describe how the total number of atoms does not change in a chemical reaction and thus mass is conserved. |
|
HS-PS1-7
Students can use the Classroom Slime Kit to construct and revise an explanation for the outcome of a simple chemical reaction based on the outermost electron states of atoms, trends in the periodic table and knowledge of the patterns of chemical properties.
HS-PS1-4
Students can use the Classroom Slime Kit to develop a model to illustrate that the release or absorption of energy from a chemical reaction system depends upon the changes in the total bond energy.
HS-PS1-7
Students can use the Classroom Slime Kit and then take it to a mathematical lesson to support the claim that atoms and mass are conserved during the chemical reaction. |
Suggested Science Idea(s)
HS-PS1-7
While using the pre-measured chemicals in the kit, students experience an introductory lesson to plastics and polymers.
2-PS1-1
5-PS1-3
Students can use the Classroom Slime Kit while making observations of many different materials based on their properties.
