Year 3 Science - Physics - Light and Shadows

Date: 19th Jan 2022 @ 2:41pm

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

As Year 3 scientists, we noticed

“Light cannot get through an opaque object.”

“The shadow is the same shape as the object.”

“A shadow is the absence of light.”

“Transparent objects can also make shadows”

We also made some other interesting observations.

“I made the shadow change size.”

“I made my shadow point in different ways.”

“I made my shadow move.”

The children will be addressing these ideas later on in the half term. 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.

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