Topic 4: Structures and stability

Materials:

Newspapers
Sellotape
Card squares
Set of kitchen weights

Task Suggested Activities
Examining various structures for stability and centre of gravity Talk about structures in the environment. Roll tubes from A3 newspaper sheets and secure with tape. Show example of simple bridge made from tubes. Test for strength with weights and stability by simulating wind and earthquake effects. Discuss how to make stronger.
Designing and building tower/ bridge from card or newspaper and testing for strength and stability Parents and children design and make their own newspaper or card tower or bridge. Test for strength and stability. Record number of weights used.
Exploring stability and centre of gravity Children stand with legs together, then legs apart and are pushed to discover which is more stable. Brainstorm for reasons why, e.g., legs make a triangular shape which is more stable. Test for centre of gravity by standing against a wall, lean forward to pick up object. Brainstorm reasons for falling forward.
Designing and creating an animal/creature. Parents and children together design and create an animal/creature using the newspaper tubes for body, arms, head, etc. Discover how to make the creature support itself. Discuss function of tail for balance
