Light KWL Chart

Year 3 ScienceLight3 pages

About this worksheet

A three-page Year 3 lesson starter for a light unit, including an answer page. Part 1 is a KWL chart. Pupils fill the first two columns now and leave the third until the end of the unit. Part 2 has four quick-fire questions. Pupils pick the three light sources from six items and fill three gaps about light. They also choose a safe way to protect their eyes from the Sun and decide if a mirror gives out light. The key lists sample K and W answers. It is aligned to the England National Curriculum for science.

Curriculum objectives covered

Light

“Find patterns in the way that the size of shadows change.”

No question tests shadow size. The key suggests "Why do shadows change size?" as a W column question, so pupils may raise it.

Light

“Notice that light is reflected from surfaces”

Question 4 asks if a mirror gives out light, and question 1 includes a mirror and a polished spoon as items that only reflect it.

Light

“Recognise that light from the sun can be dangerous and that there are ways to protect their eyes”

Question 3 asks for the safest way to protect eyes, with sunglasses and a sun hat as the answer.

Light

“Recognise that shadows are formed when the light from a light source is blocked by an opaque object”

Gap c in question 2 says a shadow forms when light is blocked by an opaque object, next to a picture of a torch and a toy block.

Light

“Recognise that they need light in order to see things and that dark is the absence of light”

Gaps a and b in question 2 cover needing light to see and dark as the absence of light.

How teachers use it

First lesson

Give pupils five minutes on the K and W columns before you teach anything. Their questions tell you where to start.

Light sources sort

Bring in a torch, a mirror and a spoon. Turn the classroom lights off and ask which ones still shine.

Last lesson

Hand back the same sheet so pupils fill the L column, then check which W questions they can now answer.
