Unit Sequence: Learning Intentions

  1. How are rocks used?- Compare and group together different kinds of rocks on the basis of their appearance and simple physical properties.

  2. Fossils -Describe in simple terms how fossils are formed when things that have lived are trapped within rock

  3. Soil testing - Recognise that soils are made from rocks and organic matter.

Scientific Enquiry: Investigations

  1. How do fossils form?

    • Plan an exploration of how fossils are made.

    • Record their observations.

  2. What is sand?

    • Record observations-what happens when rocks break up.

    • Display results using appropriate graphing methods e.g., pie chart.

  3. What is soil?

    • record their initial observations and take a photo of their soil samples

    • separate the soil with water, take another photo then measure and record the depth of each layer in both jars

    • decide whether the soil samples are sandy, silty or clay

    • record any final observations

    • display their results in a suitable way, such as in a bar chart or with labelled diagrams.

🏁 BIG FINISH
