Engineers Week 2022: Investigating Traffic Lights

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

We looked at the traffic lights just outside our school (for cars and for pedestrians), their colours and their sequencing.

Back in the classroom 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 Quality Street wrapping paper squares.

We discussed the sequencing of traffic lights and pedestrian lights in Ireland.

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

Today, after deciding on “Quality (Street)” filters, we made our own model traffic lights.
