To celebrate the 2012 Olympics, we want to build an Olympic Tower, the tallest in the UK. But first we need your help to make a scale model, with an eye-catching design, and great strength. Can you help?
Levels of difficulty:
Level 1 - Make a tower 0.5m high Level 2 - Make a tower 1m high Level 3 - Make a tower 2m high
Equipment: Large KNEX set.
Approach: What will be the best design for your tower? Can you make it really strong? Can you make a base to stop it falling over as it gets bigger? For level 2, can you come up with a pattern that you can continue higher and higher? Does it help if the pattern is symmetrical? For level 3, have you got enough KNEX to reach 2m? If not, would it be possible to make the tower thinner at the top than it is at the bottom?
