Dear Bloggers,

Years 3 and 4 have just finished a large unit of work on drawbridges.

Here is a video of the model in action with the motion sensor detecting the movement of the boat. The motor turned clockwise and the bridge moved up for 5 seconds to allow the boat to pass underneath.  The bridge stayed up for 5 seconds and then took another 5 seconds to come down after the boat had passed. This involved the motor moving anticlockwise.

Fast workers  used ‘send and receive commands’ between different computers to synchronise two bridges going up and coming down.

Thanks for calling by

Mrs Garlick
