Lesson 3
Lesson Plan
Introduction:
1. Provide pupils with copies of page 66 on thick card and colouring pencils or felt tips. Pupils colour
the wheel according to the colours on the sheet. They carefully follow the instructions to create the
Newton disc. (This may require guided work and support by adults to ensure that all pupils can
create the Newton disc).
2. Discuss with pupils how they are able to see objects such as the wheel, recall and consolidate
previous learning about light and their eyes as the reason. Ask pupils questions such as What
colours can you see when the wheel is still? What do you think you will see if you spin the wheel very
fast? Write class predictions on poster paper.
Development:
3. Allow the pupils to spin their Newton disc and to observe what happens. Play the disappearing
colour wheel video and discuss what the pupils observed and
compare it to their predictions.
4. Explain to pupils that the colour wheel represents light—it is made up of all of these colours but we
see it as white light. This white light shines onto objects and lets our eyes see colours. What would
happen if we changed the colour of the light? Would we see colours differently?
5. In small groups, pupils conduct the experiment on page 67 to see how light determines how our
eyes see colour (alternatively, this can be conducted as a whole class experiment with one set of
equipment). The teacher may wish to demonstrate how to construct the shoebox, or pre-prepare
the materials by cutting a hole in the shoebox and cutting squares of cellophane. Pupils complete
page 67 individually. As an alternative, pupils may take photographs of the results and print them
to glue into their science books.
Differentiation
• Guided group work will enable all pupils to observe and record what happens when different
light is used.
• Once the experiment is complete, challenge pupils to try using gobstoppers/bubblegum balls
of different colours in the same experiment and observe what happens.
Reflection:
6. Pupils volunteer to read out their conclusions and ensure everyone is in agreement. Discuss any
differing answers.
7. As a class, compile a list of things that pupils learnt about light that they didn’t know before.
Use the resource sheet on page 68 if required. Alternatively, scan the page and display it on the
whiteboard.
