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.

With guidance, identify questions in familiar contexts that can be investigated scientifically and make predictions based on prior knowledge
With guidance, plan and conduct scientific investigations to find answers to questions, considering the safe use of appropriate materials and equipment
Consider the elements of fair tests and use formal measurements and digital technologies as appropriate, to make and record observations accurately
Use a range of methods including tables and simple column graphs to represent data and to identify patterns and trends
Compare results with predictions, suggesting possible reasons for findings
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...
