Science at key stage 3 (Year 9)

Unit 9F: Patterns of reactivity
Section 6: b. Can metals displace each other?

Objectives

Children should learn:

that displacement reactions can be useful

Activities		Outcomes
		Children:
Demonstrate the thermit reaction between iron (III) oxide and aluminium. Ask pupils to explain where the energy to melt the iron produced comes from, and explain, eg using a video clip, the use of the reaction in welding. Use the displacement model to describe what is taking place during the reaction.		explain that energy released by the reaction is sufficient to melt the iron describe how molten iron is used in welding, eg on railway lines

Points to note

Safety

an appropriate method should be used and a risk assessment followed. Safety screens and face shields should be used
