Engineering Week: Traffic lights

Engineering Week: Traffic lights

It is engineers week.  We talked about the job that engineers do, and then we investigated traffic lights.

We discussed what opaque, translucent and transparent mean.

We sorted materials into each of these categories.

We mixed colours by putting coloured sellophane sheets against the window and we looked at the classroom through coloured paddles.

We discussed the sequencing of traffic lights and pedestrian lights in Ireland and we used the internet to  have a look at traffic lights from different countries.

We think that engineers have very interesting jobs and we hope some day that some of us might a job as an engineer.
