Moments and Levers — Interactive Lesson (Ages 11–14)

Why is a door easier to push at the handle, and how does a see-saw balance? This 17-slide interactive lesson on moments takes pupils from first ideas to exam-style explanations, with 10 self-marking activities and nothing to prepare beforehand.

Teaching Moments and Levers in KS3 Science

Pupils describe a moment as the turning effect of a force and calculate moments with moment = force × distance from the pivot. They use the principle of moments to balance a see-saw, explain how levers such as spanners, crowbars and wheelbarrows reduce the effort needed, and identify the pivot in everyday objects.

What Pupils Will Learn

• Describe a moment as the turning effect of a force.
• Calculate moments using moment = force × distance.
• Use the principle of moments to balance a see-saw.
• Explain how levers make jobs easier.
• Give everyday examples of moments.
