1.2.3 Metals and non-metals (AQA GCSE Chemistry)

Spec 2.3 Metals and non-metals (One hour suggested teaching time)

Lesson(s) preparation:

[Practical] – Investigating properties of materials (Circuit with bulb and crocodile clips, glass rod, iron nail, copper strip, piece of wood, Perspex trip, piece of ceramic etc…)
Could print slides 6, 7, 18 & 18

Rationale:

Often the comparison of metals and non-metals is overlooked. I like to get students to identify the difference in properties and then apply the properties to unknowns. Here they should notice that general properties don’t always apply to all.

Suggested teaching:

Slides 2-4: Retrieval practice starter (slide 4 is optional differentiated)

Slide 5: A general introduction to the idea of metals and non-metal and the key properties.

Slide 6: Practical (no method given as it is fairly straightforward). Get them to identify the properties of different materials in the room, depending on ability they may need support in identifying them as metals or non-metals.

Slides 7-8: Summarising the properties of metals and non-metals.

Slides 9-10: Applying properties of metals and non-metals, they will need to apply a best fit approach for some of them (like mercury and graphite!)

Slides 11-15: Introduction of how metals and non-metals form ions when they react.
