States of matter

WALHT: Observe and discuss the relation when 2 states of matter when combined.

Cornstarch is a substance which has a solid state of matter. Water is a substance which has a liquid state of matter and mixing these two substances creates a colloid which has a combination of 2-3 states of matter.

Materials:

50mls Cornstarch

15mls Water

Knife

Container

Method:

1. In a shallow clear container add the cornstarch
2. Add the water bit by bit and stir while doing the process.
3. Once done, experiment on this solution and see the changes from the state of matter.

The reaction between the substance of cornflour and water mixed together created  a solution that has the ability to have strong viscosity when strong pressure is applied to the colloid and as when you apply a gentle pressure to the liquid it instantly forms its state to a liquid.
