This lesson focused on understanding what a heterogeneous colloid is in the simplest of terms.

The lesson was comprised of lecture, activity, and demonstration. The lecture had a powerpoint with visuals – that doubled into the game. Students were asked to move to the left side of the classroom if they believed that the picture shown was a colloid and move to the right if they believed it was not. It was fun and students were able to think critically, through verbal responses should they have held a dissenting opinion.

The demonstration was on the Tyndall Effect, demonstrated through flour and water (which is a suspension and I made that clear to the students). The Tyndall Effect is where light is scattered through the material it is shone through, rather than cutting straight through.
