SLIME IS CHEMISTRY
We made slime to show how different materials combine to make new materials. We used PVA glue, borax, some shaving cream, food colouring and water. Our experts, Ellie and Shona helped everyone to make their own blob of slime.
Chemistry is all about states of matter including liquids, solids, and gasses. It is all about the way different materials are put together, and how they are made up including atoms and molecules. Additionally, chemistry is how these materials act under different conditions.
Slime is a Non-newtonian fluid. A Non-newtonian fluid is neither a liquid or a solid. It can be picked up like a solid, but it also will ooze like a liquid. slime does not have its own shape. Slime can also change it’s shape to fill whatever container it’s placed in. However, it can also be bounced like a ball because of it’s elasticity.
Slime is all about polymers! A polymer is made up of very large chains of molecules. The glue used in slime is made up of long chains of polyvinyl acetate molecules (that’s why we use PVA glue). These chains slide past one another fairly easily which keeps the glue flowing. Chemical bonds are formed when you mix the glue and slime activator together.
It was great fun.

Slimey but satisfying GREAT 🙂
My slime, I gave it away to my sister for lollies.
