Class Experience

Students will learn about non-Newtonian fluids, polymers, and cross-linking of molecules.  Students will practice following a recipe to make slime.
 1 file available upon enrollment
If you want to follow along and make slime, you will need: - a bowl - a spoon to stir the mixture - 1 cup of white PVA glue ("school glue"...Amazon sells a 1 gallon jug for about $18) - food colouring - optional add-ins (lotion, glitter, modeling clay, shaving foam, beads) - approx 6 Tbsp "activator" For the activator Option 1: Mix together 1 cup of warm water and 1 tsp powdered borax Option 2: 1. Mix together 1/2 cup of warm water and 2 tsp baking soda 2. Buy a bottle of contact lens solution - DON'T MIX the contact lens solution and baking soda solution together. For the Oobleck: - a disposable container like a foil baking pan - approximately 1 cup cornstarch - water - food colouring - spoon
Learners will not need to use any apps or websites beyond the standard Outschool tools.
1 hour per week in class, and maybe some time outside of class.
The slime we are making is not edible.  

The recipe used includes an activator that is made with borax.  Borax (sodium tetraborate decahydrate) can cause irritation of eyes, skin, and respiratory tract if it comes into contact with these organs.  I use a solution of 1 tsp borax mixed with 1 cup of water.  Gloves are encouraged if using borax. 

If preferred, this activator can be replaced with contact lens solution (contains boric acid) + a baking soda solution.  Information about this option will be given with the materials.
