Roundabouts


 

Activity content:  Very suitable for pupils working in pairs


Suitable for years 5 – 8 Taking Approx. 2 – 2 ½ hours 


We explain that a fairground ride must turn at a safe speed. The problem is that the motor turns at a very high speed which must be reduced. We show how a compound pulley system can achieve the desired speed reduction and that the reduction is dependent on the ratio of the pulley diameters.

The children can ‘customise’ their roundabout by designing and making additional features which could include: Pay kiosk; advertising panels; fences; flags and other distinctive features.      


The session concentrates on QCA  D & T unit 6C

linking it 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
 

We provide:


  • 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
