Science in Year 3

Physics

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…) then reflects off an object into our eyes.  Our brain tells us what we are looking at.

Today we played around with shadows.

“When I made a shadow I could make it move all the way around by moving the torch.” Ellie

“I noticed when my hands were further away from the torch the shadow was smaller.” Harmony

“I noticed when my hands were closer to the torch the shadow was bigger.” Phoebe

“I made different shadow puppets like a bird and a crocodile.” Holly

“Sometimes my shadow got longer and shorter but I don’t know why.” Brayden and Alfie

“I managed to make a double shadow with two torches.” Diana and Isaac

We learned that a shadow is made when a solid object blocks light from a source.

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 and understanding why they change length and direction at different times.
