We tested our boat winding up the propeller and we put it in the water with the pennies on the boat. We got it to work on the 4th try. We have a Ziploc bag on the bottom to help it stay afloat. The propeller uses elastic potential from the rubber band which moved the boat.

The challenge was to make a boat that could carry 40 grams and move 20 inches.Our design was to make the boat out of card bored and have straws on the bottom. And it propelled foreword by having a lid getting winded back and released. What we could do to improve is to make sure our card bored did not get soggy. ]]> 2019-02-07 16:55:53 UTC https://padlet.com/sterne8_1/a5kii32dagru/wish/328845171 https://padlet.com/sterne8_1/a5kii32dagru/wish/328848220 The challenge was to create a boat that would be able to carry 40 grams of weight while moving 20 inches. We tested our prototype by winding up the propeller and seeing if it could move. It ended up working and it moved the 20 inches but there was a little water leaking in so we edited it a little bit by putting another bottle cap to prevent the water from leaking in.]]> 2019-02-07 17:01:10 UTC https://padlet.com/sterne8_1/a5kii32dagru/wish/328848220 kyle_bruce https://padlet.com/sterne8_1/a5kii32dagru/wish/329279103 Showed Mrs stern photo already.
The challenge was to make a boat that can travel 20 inches while holding 40 grams. We tested our prototype by winding up a strip of foil and it was supposed to make the propeller on the back of our boat spin and make it move 20 inches to the end of the water box. Our boat was not able to complete the task. It was able to hold the 40 grams but was not able to move the 20 inches that was needed to complete the task. Our prototype did not work because of the propeller. The propeller had trouble spinning and moving the boat with it. We could have improved our design by using a rubber band to spin a propeller or a object and get it to move.]]> 2019-02-08 16:28:43 UTC https://padlet.com/sterne8_1/a5kii32dagru/wish/329279103
