Light Year 3 Science
Light In this lesson, we will be: Thinking about how shadows are made; Going on a shadow hunt; Investigating the size of shadows.
Light Our learning objectives today are: To be able to explain that shadows are formed when light from a source is blocked; To recognise that shadows are similar in shape to the objects forming them; To be able to describe how to change the shape of a shadow.
Can you remember what opaque means? opaque light dark straight line light source distance object block shadow Light: key vocabulary You will need to practise writing and spelling these words.
Light Today s big question: What do you think a shadow is?
Light Activity A We re Going on a Shadow Hunt
Light Activity A: We re Going on a Shadow Hunt If the weather is fine, go out and look carefully at shadows. If not, turn a few lights on inside or use torches to create shadows.
Light Activity A: We re Going on a Shadow Hunt Record your observations on paper or in a notebook. You could sketch or take photos of the shadows that you find.
Light Activity A: Shadow Hunt Things to think about:
Light Activity A: Explore your own shadow! Move into different positions: stand, crouch and extend your arms and legs. Make your shadow as thin/fat or short/long as you can!
Light Activity B We re Going to Investigate How Shadows are Made You will need: Scissors Card A torch Paper for a screen
Light Activity B We re Going to Investigate How Shadows are Made Cut a simple shape out of the card. Shine your torch at the card.
Light Activity B We re Going to Investigate How Shadows are Made Can you draw a diagram to show how shadows are formed? Move the card around to see how it affects the shadow. Try to make the shadow of the card appear on the paper.
Light Activity C We re Going to Investigate How to Change Shadows You will need: A torch A ruler Paper for a screen A short stick
Light Activity C We re Going to Investigate How to Change Shadows Over to you! Can you design and carry out an experiment to show what happens to the shadow of the stick, when the distance between the torch and the stick is changed?
Light Activity C We re Going to Investigate How to Change Shadows Can you record your results in a table? Remember to work systematically!
Light Activity C We re Going to Investigate How to Change Shadows What do they show you about the effect of distance on the size of a shadow? Look carefully at your results
Light Activity D Conclusions Is this a giant baby? The closer an object is to a light source, the larger the shadow it casts.
