In this investigation, students extract iron from a breakfast cereal and consider how our bodies are able to digest iron by looking at its reactions with hydrochloric acid.

From Solar Spark, this practical activity explores the reactions at electrodes in an electrical circuit. A solar cell contains two electrodes. Different reactions happen at each electrode so that electrons can move around the circuit to give an electric current. In this experiment students use filter paper soaked...

This chemistry extension module from the Salters’ Science course deals with the energy changes which accompany chemical reactions. Photosynthesis is considered as the fundamental source of energy to sustain life process, and respiration as the mechanism for coupling the energy to body processes. ‘Calorific values’...

This block of resources provides 6 sessions on materials aimed at Year 2. They explore the useful properties of materials with a range of investigations involving absorbency and flexibility.  These include activities for finding out which type of kitchen towel or cloth is most effective at mopping up spills,...

This booklet is part of the ‘Innovations in Practical Work’ series published by the Gatsby Science Enhancement Programme (SEP). Plastics – or polymers as they are more correctly called – look set to be the material of the future. Think of any product and it is likely that it consists, at least in part, of a polymer...

In the context of finding out why we grit roads in winter, students are shown what happens when salt is sprinkled onto ice lollies.  They are then asked If they believe that the temperature of the ice lolly with the salt will increase or decrease, causing it to melt faster. Students then investigate some...
