'A core activity'. Cut out sets of the 14 ‘Core evidence cards’ provided in the activity. Give a set to each group of pupils and ask them to sort the cards to show the evidence we have for the composition of the Earth’s core. Tell the pupils that the evidence may be on a single card, or a series of cards linked together, while some cards may contain no evidence for the
core’s composition. When they have sorted their cards, ask them to suggest what the composition might be, and give the evidence that supports this idea.
This is one of many activities in the 'Investigating the Earth' category.
