The video e-lesson presents 2 experiments of the Mpemba effect and the suggested explanations.
Learning objectives:
- To study different temperatures of waters and ways to reach them.
- To observe the experiment of warmer water which can freeze faster than colder water.
- To study terminology like: freezing, boiled, melting, evaporation, convection, frost, solutes, thermal conductivity.
- To observe when the water reaches 0 °C or 100 °C
