Science:
QCA Unit 3F: Light and shadows
· that opaque objects/materials do not let light through
· that shadows of objects in sunlight change over the course of the day
· that shadows change in length and position throughout the day
Scientific enquiry
· consider what sources of information they will use to answer questions
· deciding what evidence to collect
· deciding whether evidence is sufficient to support conclusions
Literacy
· make contributions relevant to the topic and take turns in discussion
· present findings to other groups
Numeracy
· use standard measures
· use tables and bar charts to record results

Introducing the activity
· Display Page 1 through a projector or as an OHT. What is the image showing? What do the children think? Did they notice that the weather in August 2008 was less sunny?
Discussion starter:
How can we measure how much sun we have had in a day?
Children to talk about it in groups.
Discuss their first ideas.
Leading the main activity
· Display Page 2 through a projector or as an OHT. What are the images showing?
Discussion questions:
How come there is still a shadow even though the Sun is behind a cloud?
What if the sky was totally cloudy?
What happens when bright sun goes behind a cloud briefly?
Can shadows be faint and dark? When?
Children to talk about it in groups.
· Display Page 3 through a projector or as an OHT.
· Display Page 4 through a projector or as an OHT. Print off copies for the children. Children to work in pairs to make observations from their practical investigation and display their findings
Discussion questions:
What are your conclusions? How did you make your conclusions?
Do you think this investigation was a good way of measuring sunshine?
Would you change it? How?
