Parade Float
Problem: Can I make a parade float that can travel 50 cm and hold 100g?
Hypothesis:I think that I could make a parade float that could travel 50cm and hold 100g.
Materials:
4 elastic bands
4 plastic golf balls
a lot of cardboard
cotton
paper
small blue plastic cup
2 thin light blue pipe cleaners
masking tape
Method:
First I drew a picture of what I wanted my float to look like. Next I got 1 piece of cardboard that was about 27cm long. Then I got two bamboo sticks and taped one to the bottom of the cardboard and the other one behind it. Next I took 4 plastic golf balls and slid them on the ends of the bamboo sticks and put pink elastics on the ends so the balls don’t fall off. Then I took a piece of cardboard and cut a piece that was 10cm and drew a dog on it. Next with the leftover cardboard I cut it to a piece that was 10cm and drew a bone on it. Then I put cotton below the bone and dog I drew. Next I cut out a balloon out of cardboard and wrote dog rule and puppies rule on it. Then I cut an oval out of cotton and got a blue little cup and glued it on the cotton. Next I took cardboard and cut it to a piece that would fit in the cup and drew a dog on it. Then I put cotton on the top of the cup and inside. Finally I took two thin light blue pipe cleaners and zigzagged them and taped them on each side of the parade float.
Results: My parade float ended up holding 100g and traveling 50cm of a ramp.
