A Little Experiment!!

Solid or liquid???

You will need:

A container
A little water
Cornflour
A spoon

1. pour a little water into the container
2. add the cornflour a little at a time
3. mix until you have a thick ‘mush’
4. what happens when you put the spoon into the mush (it sinks)
5. what happens if you hit the surface? Is is solid?
6. touch it. What happens? The quicker you are, the more solid it will feel.
7. knead it. What happens? It forms a ball. What happens if you stop? It becomes liquid again!!
8. finally, can you drop a ball into the container? As it falls, what happens? It bounces and then sinks.

Science is amazing!!!!
