Lesson details

Key learning points

Scientists make observations and measurements to help them to learn more about the world and how things work.
Scientists review the results they have collected to decide what happened and explain what they have found out.
We can use words ending in -er to explain how one thing affects another thing.
When the object is closer to the light source, it blocks more light and this makes the shadow appear bigger.

Keywords

Object - An object is something you can touch but something that is not usually a living thing.
Shadow - A shadow is a dark shape that is formed when an object blocks a source of light.
Distance - Distance is how far away something is or how far an object has travelled.
Light source - Something that is a light source produces its own light.
Results - The results of a test or enquiry is what happened and what was found out.

Common misconception

The size of a shadow does not change.

Explanation of how the size of shadows change depending on the distance of the object from the light source.

Create sentence stems to support pupils in explaining how the distance of the object from the light source affects the height of its shadow: "The . . . . . . . . . . -er the object’s distance from the light source, the . . . . . . . . . . -er the shadow."
