Term 1 Week 4 Electronics

Today we had Andrew come to teach us about electronics. We learnt who was hottest and coolest. I was hoping to be the coolest but I was not because the  milk was the coolest. But I did not know who was the hottest. 

We tried everywhere and a place that was warm was outside near the yellow sphere.We tried near the heater but still it was not the warmest or the coolest. The reason we knew was the flashes if it was long then it was 10 but if it was a short then it was 1

Here are some photos of the electric boxes.
