In Science this week, we created land yachts then we finally raced them. Our goal was to make our Land Yacht as fast as possible. we created them with: Plastic bag plastic mini wheels bamboo sticks, We were in groups of 3-4-5, but I wasn't here for that at the time. The speed of one other group is... They went 4.5m in 7.3 seconds.
4.5m divided by 7.3s = 0.616m/s
Conclusion: In the end the force of the leaf blower made this group go far and it went well only because of the wind from the leaf blower.
