A Little Experiment!!
Solid or liquid???
You will need:
A container
A little water
Cornflour
A spoon
- pour a little water into the container
- add the cornflour a little at a time
- mix until you have a thick ‘mush’
- what happens when you put the spoon into the mush (it sinks)
- what happens if you hit the surface? Is is solid?
- touch it. What happens? The quicker you are, the more solid it will feel.
- knead it. What happens? It forms a ball. What happens if you stop? It becomes liquid again!!
- finally, can you drop a ball into the container? As it falls, what happens? It bounces and then sinks.
Science is amazing!!!!
