SC23.4.11: Construct explanations of Earth's changes over time through slow and…

Restless Earth: Fossils, Soils, Volcanoes and Plates Grades 4–7 · partly supports this outcome

Press model fossils and read a cliff of layers, shake a jar of soil and watch it sort itself by grain size, plot real volcanoes and earthquakes on a world map to find the edges of Earth's plates, then move model plates and test a building on a shake table. Four hands-on lessons that build on Rocks and Erosion.

• How do fossils form, and what can they tell us? 55–70 min

  Teams press shells and leaves into clay to make a mould and a salt-dough cast, build a cliff of coloured layers with a different model fossil in each, and swap cliffs to work out which layer is oldest. They then read a cliff of real fossils and explain that a place once under the sea is now dry land.
