Light and Shadow

This half term we are investigating light and seeing.  We already know that light from a source (such as lamps, the sun, torch, candle…) reflects off an object into our eyes.  Our brain tells us what we are looking at.

Today we played around with shadows.

Harley explained, “When you shine a torch on a solid object it makes a shadow on the white paper.”

Emilia noticed, “When I shone my torch through a transparent object I could see a light shadow of the water. The torch shone right through the bottle.”

Erin commented, “When we moved the torch from side to side the shadow moved places and changed direction.”

Jasmine said, “When you move the torch up the shadow gets smaller and when you move it down it gets bigger.”

Olivia thought, “If the torch is held at a different angle, the shadow gets longer and shorter.”

Olly concluded, “The shadow is always the same shape as the object.”

All the children agreed that this was a lot of fun and every single scientific conclusion was made by their own observations and reasoning.

Year 3 will be also studying shadows made by the sun throughout the day.
