Science KS 3 Unit 9E Reactions of metals and metal compounds

In this unit pupils:

• explore the properties of metals and non-metals.
• learn that different acids react in similar ways with metals, with metal carbonates and with metal oxides.
• represent elements by symbols and compounds by formulae.
• use word and symbol equations to describe these reactions.

In scientific enquiry pupils:

• describe patterns in qualitative data about reactions.
• use patterns in reactions to make predictions about other reactions.
• devise and evaluate a method for preparing a sample of a specified salt.

This unit is expected to take approximately 7.5 hours.
