Science:
QCA Unit 1E: Pushes and pulls
· that pushing or pulling things can make objects start or stop moving
· to identify similarities and differences between the movement of different objects
· to make suggestions about how objects can be made to move and to find out whether they were right
Scientific enquiry
· making observations and communicating these
Literacy
· take turns in speaking
· make contributions to discussions
· clarify ideas

Introducing the activity
· Display Page 1 of the activity through a data projector or on an OHT. Discuss the images with the children. If possible, show the children the clip on YouTube and discuss the contraption. How does the egg move?
Discussion starters:
- What could you do to start the egg moving?
- How would you keep the egg moving?
- How would you stop it?
Leading the main activity
· Display Page 2 through a data projector or on an OHT. Here there are examples of pushes and pulls. Look at each of them and encourage the children to explain how each makes the egg move.
Discussion starters:
- Is it a push or a pull?
- How does the egg move?
- How could the egg be crushed?
· Display Page 3 through a data projector or on an OHT. Print off copies for the children as appropriate. They need to label each part of the machine as a ‘push' or ‘pull'. Then give the children the opportunity to design their own egg crusher. Perhaps provide a variety of items e.g. ramps, balls, dominoes, string, toy bricks etc. so that the children can try out methods such as pendulums, staircases, domino runs etc.
