Have you ever sat on a rocking horse, and rocked happily backwards and forwards? Have you ever thought about how rocking horses are made?
Levels of difficulty:
Level 1 - Make a model of a horse for a doll to sit on. Level 2 - As level 1, with reins and a saddle that can be taken on and off Level 3 - As level 2, and add rockers so that it rocks back and forth
Equipment: KNEX set, plus a plus a doll about 30cm high.
Approach: How could you make a horse out of KNEX? How will you make the body? And the head? And the legs? Can you make it the right size and shape for your doll to sit on? For level 2, what shape and size of saddle will you need? How can you fasten reins on to the horses head? For level 3, what shape will the rockers need to be? What KNEX rods and connectors will be required?
