Upper Key Stage 2
Link to the National Curriculum
Sc4 Physical Processes (Electricity)
Non Statutory Guidance
pupils might work scientifically by:
- Designing and making a set of Traffic Lights
- To build upon the experience of electrical circuits the children will have gained in the lower Key Stage 2 setting.
What you need
- Electrical wire
- Bulb holders/ bulbs
- Battery holder
- Drawing pins
- Paper clips
Other additional equipment relates to the wood required to make the Traffic Lights system. This can be easily made by children of the upper Key Stage 2 setting using junior hacksaws, bench hooks and glue guns( either by the teacher or under strict guidance, depending on the school’s H/S policy. Making this equipment is explained in the video clip.
What you do
- Watch the video from the website: practicalprimaryscience.co.uk
- Lay the apparatus on its side for ease of working
- Fit the tree bulb holders and bulbs in position
- Fix up the wiring as shown in the video clip
- Attach the battery holder and batteries to the side of the apparatus.
- using the paper clip / drawing pin switch test the lighting sequence: Red, red and amber, green, amber and then back to red.
Group / Class Organisation
- Depending on the availability of additional adult help, experience of the children in terms of practical work and apparatus / resources available, split the children into groups of threes/ fours to undertake the activity.
How it works
- To enable the bulbs to light up in sequence requires complete circuits. once the children have mastered this concept then circuit construction applied to any situation becomes a formality with the skills transferred appropriately
- This work could take the form of a broader theme related to Road safety in general and in that way immediately the children are engaged because it becomes a real investigation where their own personal experiences can be brought to bear.
Follow up work
- Introduce the children to further challenges that require electrical solutions. Very often these can come from literature e.g. The Iron Man by Ted Hughes.
- Challenge the children to make a model of the Iron Man complete with flashing eyes!
