Walt: Understand dark and light


 What Is Light? Share the questions on the Lesson Presentation and discuss them with the children. Use the Light Mind Map Activity Sheet to find out what the children already know about this topic, and what they would like to find out about light.


 Sources of Light: Use the Lesson Presentation to explain light sources and discuss some examples. The children talk to their adults/siblings to identify light sources, using what they can see at home as a starting point.


 Light Source Sorting Game: Using the differentiated Light Sources Sorting Cards, the children work in a partner to sort their sets of cards into objects that are light sources and those that are not.


 Light Source Sorting Game - The Tricky Ones! Use the Lesson Presentation to explain the reason why tricky objects like the moon, a window and a mirror are not light sources. Address any misconceptions about these objects.


 What Is Dark? Talk to the children about dark and explain that it is the absence of light. Ask them about their own experiences of dark, such as places that are dark, or times that it is dark. Discuss which light sources are absent in these places or at these times in order to make it dark. Can we see in the dark? Discuss the idea that we cannot see in complete darkness, but it is rare to find this. There is often light from street lamps, a night light etc. that allows us to see objects, but not as clearly as in full light.


 What’s In the Bag? Place 5 feely bags around the room. Use the Lesson Presentation to introduce the idea that it is dark inside the bags so we cannot see the objects they contain. Children visit each bag and fill in their What’s In the Bag? Activity Sheet. Ask how we can illuminate the objects by getting light into the bags. Open the bags and allow children to revisit the bags and add to their What’s In the Bag? Activity Sheet.


 Light and Dark: Children should complete their differentiated Light and Dark Activity Sheet to show what they have learnt in the lesson. Look for children who have a good understanding of light and dark and how we need light to see.
