Speed of light

We had a beautiful day for Mrs. Dudley’s class’s outdoor learning session this week.

We talked about the speed of light and the speed of sound – it’s amazing how much faster light is! Light travels at 670,616,629mph while sound is a snail-like 761mph.

We saw this difference in action by sending some children onto the playground with a metal tray and a mallet. At the signal, we were all quiet as they banged the tray. We saw them move a fraction of a second before we heard the noise.

We also marked where a shadow fell at noon. We’re going to see if it’s in the same place next week.

After that we learned how to lash sticks together and had a go at square lashing. It’s harder than it looks!
