Science Week – Knex Challenge – Maple Class

Day 2 of Science week and we were challenged to build a car out of Knex – sounds simple?  However our car had to be able to travel fast, carry a ball and also contain a magnet so that we could use magnetic forces to move it.  Initially we built some really elaborate designs until on our first round of testing we discovered there were many issues, some couldn’t steer, many didn’t travel far and some even lost the ball!  After considering how we could improve our designs we were able to test our designs to see how they met the criteria.
