We have been talking about materials: what are they made from? what do you use them for? are they solids or liquids?
We have watched some interesting Tigtag films about solids and liquids.
Today we made a really interesting solid/liquid.
Teacher had a bag of cornflour. She mixed it in a basin with water.
The mixture looked like a liquid and it poured like a liquid, but we could make balls out of it, and it was hard when we punched it so it must be a solid too.
It is called a non Newtonian liquid and it acts like a liquid unless force is applied, then it turns into a solid.
We love this gloop and we watched a really interesting video clip about it.
