Today in 6B, we were investigating how light rays from the sun affect the length of shadows throughout the school day. Our main item of equipment was the sun, which thankfully remained usable for the whole period of measuring.
Every half hour, a group of three students went outside to measure the length of the shadow created by their 30cm ruler.
Using our data, we concluded that as the sun rises up to it’s peak, the shadow length decreases. This is because the angle of the light rays from the sun increases as the earth spins on its axis. Thankfully, this is what most other scientists think too!
