A 60 minute lesson in which students will investigate push and push forces at work in the playground.
As a class, revise pushes and pulls by playing the Rock and Roll forces game on the BBC Bitesize website. Start on the medium level and move up to higher levels if the students are coping with the content.
Display and discuss slide 10 of the Push and Pull PowerPoint. Encourage the students to suggest various pieces of playground equipment which may use push and pull forces.
Provide the students with a copy of the Playground Forces Worksheet. Read the instructions to the students and answer any questions they may have about the task.
Go for a walk to the playground. Give the students time to explore the equipment. Encourage them to take turns with their partners and discuss the forces that are at work.
Return to the classroom. Monitor and support the students as they independently complete their worksheets.
As a class, discuss the different pieces of playground equipment and whether they use a push force or a pull force. If the students do not agree with each other, allow them to justify their opinions through discussion. Pose questions for them to reflect upon, such as:
Are push forces or pull forces more common in the playground?
Is it possible for playground equipment to use both push and pull forces?
Which pieces of playground equipment do you most enjoy using? Why?
Encourage more confident students to design their own pieces of playground equipment that require either a push or a pull force (or both).
Pair less confident students with a supportive peer tutor who may be able to assist them in completing the playground equipment investigation.
