A science experiment which explores the change of state from solid to liquid.
This teaching resource should be used in conjunction with the Let’s Experiment! – How Long Will It Take to Melt? video. This video provides a complete demonstration of the experiment.
For safety reasons, students should not attempt this experiment themselves.
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 investigate!
This Chemical Sciences experiment allows students to investigate whether solids take the same time to melt when the same amount of heat is added.
Students follow the scientific method to make predictions, record and interpret data, and draw conclusions.

A change of state between solid and liquid can be caused by adding or removing heatElaborationsinvestigating how liquids and solids respond to changes in temperature, for example water changing to ice, or melting chocolate (Skills: Numeracy, Critical...
Represent and communicate observations, ideas and findings using formal and informal representations
Compare results with predictions, suggesting possible reasons for findings
Consider the elements of fair tests and use formal measurements and digital technologies as appropriate, to make and record observations accurately
With guidance, identify questions in familiar contexts that can be investigated scientifically and make predictions based on prior knowledge
Use a range of methods including tables and simple column graphs to represent data and to identify patterns and trends
With guidance, plan and conduct scientific investigations to find answers to questions, considering the safe use of appropriate materials and equipment
