Day and night experiment:

1. Your teacher will put you in small groups or learning teams.
2. You will be given a torch and the room will be darkened.
3. One member of your group will be the sun (holding the torch), one the member the earth and the other members the observers.
3. The sun stands still and shines the torch on the Earth.
4. The Earth needs to slowly rotate (spin). What do you notice about the light shining on Earth?
5. What do you think causes day and night?
6. Can you draw and label a diagram to explain your thoughts?
Extension: Use a flip camera to record your group’s demonstration.

Shadow tag game (Primary Connections Idea):

Before you begin, discuss the following in small groups or learning teams:
1) What is a shadow?
2) What is needed to make a shadow?
3) How do shadows change?
4) Play a game of 'shadow tag'. You will need a partner. One partner is 'it' and tries to tag their partner's shadow. Then the other partner becomes 'it' after being tagged.
5) Does your shadow move in the same direction as you?
6) How can you make your shadow smaller?
7) What is the biggest shadow you can make?
8) Reflect in your Science journal.

Cross Curriculum Ideas:
1) Use a digital camera and take images of shadows around your school.
2) Do a 'shadow' search on tag galaxy and discuss the images. What do you notice about the shadows? Where do you think the sun is located in relation to the shadow? If you have a SMART board your teacher may use the 'transparency layer' to investigate this. You teacher may like to view this video tutorial.
3) Make shadow puppets during are and create shadow plays during drama.
4) Investigate time (ACMMG062) in Mathematics. Below are some online resources:
Interactive Clock
Interactive Clock 2
What time is it?
iR Teaching Time Interactive Games
What will the time be? BBC Games

How big do you think they are? (Primary Connections Idea):
The Sun, Earth and Moon are all spheres. But did you know that for a long time, the Earth was thought to be flat?
1. Why do you think people thought this? Record your thoughts in your Science journal.
2. Your teacher will download the SMART Notebook document or the document for you to work through as a class.

For teachers: Formative Assessment
Students:
- Make predications
- Carry out an experiment
- Record results and observations
- Suggest possible reasons for their findings
- Describe relative sizes of the sun, Earth and moon
