This week we designed small boats that were to travel across a tub of water by fan. My partner Lauren and I decided to use a thick piece of foam for the base of the boat, a chopstick for the keel, a plastic stick for the rudder, another chopstick for the mast, and a tissue and a small piece of foam for the sail. We had to hold 20 marbles in our boat, so in order to hold them, we added half of an egg carton to the base of our boat! We chose this design because the tissue and foam on the sail allowed room to catch the wind and allow it to travel quicker, the foam and egg carton base was sturdy enough to float on top of the water for multiple runs/held the marbles in nice little compartments, and the chopstick keel and plastic rudder helped the boat to travel in a semi-straight line across the tub of water.
The final results of our boat turned out very well! Our average time was 2.69 seconds, which was the third quickest in our whole class! There is nothing I would have changed about our boat. It did a great job floating and staying upright, as well as traveling quickly across the tub of water. Yay!
Adios fishies.
