Activity content: Suitable for years 5 – 8 Taking Approx. 2 – 2½ hours
Pupils produce excellent results when working in pairs.
We explain that a fairground ride must turn at a safe speed. The motor turns much faster than needed and this must be reduced. We show how a compound pulley system achieves the desired speed reduction and that this reduction is dependent on the ratio of the pulley diameters.Introducing the concept of gearing.
The children can ‘customise’ their roundabout by designing and making additional features which may include: Pay kiosk, advertising panels, fences, flags and other distinctive features.
The session concentrates on QCA D & T unit 6C (and linking into Science & Mathematics)
Design & Technology, Science
Aims - the session will:
- Provide the experience of making a model roundabout
- Develop practical skills in assembling the roundabout
- Provide opportunity to use knowledge from the NC in Science and to add simple switches to control the models.
Objectives - are to:
- acquire the construction and assembly skills required to make the roundabout.
- learn new vocabulary related to the activity
- evaluate the model
- suggest modifications, make and test them
- make electrical connections to the motor and battery
- design and build additional features into the model.
- Tuition for a half day session with your class
- A set of models (normally one between two pupils)
- Work books for pupils’ use
- Ideas for extending the session afterwards, incorporating elements of the National Curriculum in Science and Mathematics
- A list of spares together with a supplier’s address from whom the school can replenish consumables.
We will bring:
- Boards to protect your tables
- Our pre-packed kits for your pupils
- Simple hand tools
