The Lighthouse - getting started

What happens when you click on this flow chart and select RUN? Explain in the next cell.

The sequence starts The light turns on It stays on for two seconds The light turns off It stays off for two seconds The sequence keeps repeating

If you wanted the lighthouse to come on for two seconds then go off what would you write in the sequence?

Do it and test it. Does it work? Yes - this is the chart (below)

Can you put the indoor lights on so that they stop on all of the time and the other flash on and off? Yes (see charts below)

Level 3

Pupils use ICT to save information and to find and use appropriate stored information, following straightforward lines of enquiry. They use ICT to generate, develop, organise and present their work. They share and exchange their ideas with others. They use sequences of instructions to control devices and achieve specific outcomes. They make appropriate choices when using ICT-based models or simulations to help them find things out and solve problems. They describe their use of ICT and its use outside school.

These flow charts control various aspects of the mimics on the lighthouse picture. This work shows progression in the understanding of the pupil. From working out what the first chart does the pupils is able to modify it for his own purpose. The next step is to use the question to see whether the sun is in or out because that should determine whether the indoor lights are on or off. (See the next exercise)
