This is a problem-solving activity in which students are engaged in a challenge is to control virtual bridges using expansion and contraction so that a car can pass over them. In so doing they learn about the expansion of solids, liquids and gases when heated is applied. Students need to understand how a bimetallic strip works.
This simulation allows students to change the temperature and observe the changes at macro and micro level to water. It reinforces the Particle Theory.
Substances that are very cold have different properties to substances that are hot. Watch as the Surfing Scientist uses hot and cold water, food colouring and a fish tank to demonstrate what happens when water at different temperatures is mixed together.
