Outcomes |
|
Children: |
- Repeat the previous lesson but use a light meter to monitor light and darkness. Ask the children to design a simple lighthouse using a bulb, a cardboard tube and a light sensor. Tell the children they are now going to make their lighthouse work.
- Ask the children to write a procedure to make the lightbulb flash every second. Ask the children to draw a diagram of their lighthouse and show where the wires are plugged into the control box. Allow them to test and amend their procedures. Now ask them to use the light sensor to make the sequence occur when it is dark and not when it is light.
|
|
- learn how to write a procedure to check two inputs and an output event

|
Points to note |
Children who find this activity difficult should only try to turn on the bulb when it gets dark. Children who find the work easy could vary the sequence of flashes to include a Morse code message.
