These resources will be removed by end of Summer Term 2025.

Switch to our new teaching resources now - designed by teachers and leading subject experts, and tested in classrooms.

These resources were created for remote use during the pandemic and are not designed for classroom teaching.

Lesson details

Key learning points

  1. A cross-section diagram shows the inside of something.
  2. Cross section diagrams are usually vertical or horizontal planes.
  3. When drawing cross sections, one plane is the main view.

Keywords

  • Cross-section - the inside view of a 3D object when cut straight through

  • Plane - a completely flat surface that goes on forever in all directions

  • Vertical - an up-down direction or position

  • Horizontal - side to side, like the horizon

Common misconception

All cross-section diagrams show the vertical plane.

Cross-sections diagrams can show the horizontal or vertical planes and these can provide very different views.

As an additional activity, pupils could cut open fruits/vegetables using vertical and horizontal cuts to observe the difference in view. Pupils could also sketch these views.
