Easiest Classroom Slime

If you’re looking for the easiest classroom slime recipe that is easy for teachers and students, doesn’t require a ton of ingredients, you’re in the right place!

For the last several years, my students have been crazy for slime.

I have been crazy about avoiding making slime in the classroom because I’ve never found a recipe that is truly classroom-friendly, teacher-friendly, and student-friendly.

All that has changed when I did a little experimenting and discovered the easiest classroom slime.

Why Make the Easiest Classroom Slime?

Kids love it, so it definitely ups the engagement factor. Plus, with so many add-in options like colors and/or essential oils, it can be a great way to end a unit.

Slime is great for teaching about properties of matter, and it’s just plain fun. Think solids, liquids, and gases. Think mixing solutions.

Not to mention teamwork, collaboration, trial and error, and it’s absolutely perfect for teaching the scientific method.

Materials for the Easiest Classroom Slime

Plastic 4 Cup Measuring Cup (available on Amazon, but I got mine from Dollar Tree)
Elmer’s School Glue
- White (great for adding a color)
- Clear (great for adding glitter)
Water
Liquid Starch (I found the same kind at Wal-Mart too)
Jumbo Craft Sticks (for mixing/stirring)
Essential Oil (optional)
Food Coloring or Tempera Paint (optional)
Sandwich Ziploc Bags

Process for the Easiest Classroom Slime

Give each group a measuring cup with 8 oz. of glue already poured in it
Give each group jumbo craft sticks (I gave one for each member of the group)
Students will add 8 oz of water (I saved 6 of the 8 oz. plastic water bottles to have it already measured, but ready for students to pour)
Students take turns mixing until glue and water are incorporated
Add a few drops of food coloring or tempera paint (optional)
Add a few drops of essential oils (optional)
Mix until incorporated
Next, add in liquid starch
1. Start by adding 4 oz of liquid starch to each measuring cup. We ended up having to add about 10 oz of liquid starch to each group, however, I’ve read that it really depends on your location – the more humid the climate, the more liquid starch you’ll need. For reference, I live in Florida, and we made this at the end of November.
Students take turns mixing until everything is really, really incorporated well. We found that more of an up and down motion worked better than just stirring.
Students can each take a handful of slime and place it in a ziploc bag to take home

Tips and Tricks for Easiest Classroom Slime

The first time we made slime, it was NOT the easiest classroom slime. I originally had students do the mixing in a gallon ziplock bags and it was a disaster. It was too hard to mix, and it just added a level of frustration for everyone, and it was SUPER messy.

My best advice is to use the measuring cups for each group. It’s easier to add more of something if you need to, easier to mix, and far less messy.
