Solid or liquid?

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

Today the year 8’s had to create a colloid (colloid is 2 states of matters combined into one, no one actually knows if its liquid or a solid )

First everyone had to pour 15 ml of water into a container of corn flour. Next the kids had to stir the water and by the looks of it every stir they made, the mixture got harder and harder but once they stopped stirring, the hard mixture turned straight into liquid. The conclusion was that applying pressure into the mixture will turn the mixture into solid and solid is one of the states of matter and if there is a lack of pressure the solid will transform into a liquid in seconds. It is the most satisfying thing to watch when a hard solid just melts into liquid.
