This engaging and interactive video demonstrates a science experiment which explores the change of state from a solid to a liquid.
Adding heat to a substance increases its temperature. If the temperature of a substance is increased enough, this can lead to a change of state. Solids can be changed into liquids by adding heat. But do all solids take the same amount of time to melt? Let’s experiment!
Will solids take the same time to melt when the same amount of heat is added? This video guides the students through a complete scientific investigation, step-by-step. Students follow the scientific method to make predictions, record and interpret data, and draw conclusions.
The Science Experiment – How Long Will It Take to Melt? teaching resource accompanies this video. Students will require a copy of this resource as they are watching the experiment.
