Levers in action
Lesson details
Learning outcome
I can identify and apply each lever system to various sporting actions.
Key learning points
- Sporting examples of a first class lever include the neck when heading the ball in football.
- Sporting examples of a second class lever include plantar flexion at the ankle during a jump shot in basketball.
- Sporting examples of a third class lever include flexion of the elbow in a bicep curl.
Keywords
First class lever - fulcrum is placed in the middle bewteen the load and effort
Second class lever - load is placed in the middle bewteen the fulcrum and effort
Third class lever - effort is placed in the middle between the load and effort
Mechanical disadvantage - 3rd class levers cannot lift as heavy loads with the same amount of effort as 2nd class levers due to the position of the effort and load from the fulcrum
Common misconception
The effort in a lever starts in the belly of the muscle.
The effort from a muscle will start from the muscle insertion. The insertion is the tendon attached to the bone which that muscle moves.
Teacher tip
Keep the drawings simple and have the Post-it notes ready to place the shapes onto images of sporting actions. This way the middle components can be identified.
Equipment
Post-it notes. Various images of sporting actions.

We use learning cycles to break down learning into key concepts or ideas linked to the learning outcome. Each learning cycle features explanations with checks for understanding and practice tasks with feedback. All of this is found in our slide decks, ready for you to download and edit. The practice tasks are also available as printable worksheets and some lessons have additional materials with extra material you might need for teaching the lesson.
The assessment exit quiz will test your pupils' understanding of the key learning points.
Our video is a tool for planning, showing how other teachers might teach the lesson, offering helpful tips, modelled explanations and inspiration for your own delivery in the classroom. Plus, you can set it as homework or revision for pupils and keep their learning on track by sharing an online pupil version of this lesson.
