Assessment for Learning is an effective way of actively involving students in their learning.  Each session plan comes with suggestions about how to organise activities and worksheets that may be used with students.

If you teach primary science, see the headings below to find out how to use this resource:

Skill development

Children will develop their working scientifically skills by:

  • Asking their own questions about scientific phenomena.
  • Using appropriate scientific language and ideas to explain, evaluate and communicate their methods and findings.
  • Finding things out using a wide range of secondary sources.

Learning outcomes

Children will:

  • Compare and group together different kinds of rocks on the basis of their appearance and simple physical properties.
  • Describe in simple terms how fossils are formed when things that have lived are trapped within rock.

Concepts supported

Children will learn:

  • How sedimentary rocks are formed and that the process takes a long time.
  • That fossils are found in sedimentary rocks, why this is and how fossils are formed.

Suggested activity use

The activity could be used in conjunction with a literacy focus on explanation texts. Children can work together to gather information about how sedimentary rocks are formed, before writing this up as an explanation text.

Alternatively, this activity can be used as a group activity, where children are given the sentences about how sedimentary rocks are formed, and they have to use the diagram to help organise the sentences into chronological order. This would promote discussion and questioning within the group, whilst being supported by an adult.

With both these suggestions, it may be useful to have a collection of different sedimentary rocks available to the children.

Practical considerations

You may need to source a collection of sedimentary rocks, prior to the lesson.
