Science KS 3 Unit 9F Patterns of Reactivity

In this unit pupils:

• learn that although metals react in a similar way with oxygen, water and acids, some react more readily than others.
• establish and use a reactivity series for metals.
• represent chemical reactions by word and/or symbol equations.

In scientific enquiry pupils:

• use a proposed reactivity series to make predictions.
• present qualitative data in a way which enables patterns to be described.
• investigate the relative reactivity of different metals, identifying and controlling relevant variables.

This unit is expected to take approximately 7.5 hours.
