Title: Rubberband Boat

Categorize: Science

This week in science to study potential and kinetic energy we created a moving boat using 2 rubber bands, 5 popsicle sticks, cardboard, 24 inches of tape, and 4 paper clips. To create the boat we went through the engineering design process, which is shown below.

My original boat: 

My original design is….2 sticks, slingshot and paper clips  

I believe my original design will allow the boat to stay afloat and move through the water because…we added paper clips for support on our boat 

When I put my boat in the water tub this is what happened: it flung into the water

The changes I am going to make to improve my boat design are…we are going to take the paper clips off. maby add cardboard and we are rebuilding our boat with more tape.

My re-built boat: 

I believe my new design will allow the boat to stay afloat and move through the water better because…it did

When I put my newly designed boat in the water tub this is what happened…. it floats and went farther in the tub

Some more improvements I could make to my boat are…. everything

This challenge was comfortable because…it was easy 

This challenge was difficult because… I did not like my group

This taught me about potential and kinetic energy because…the band potentially flung the raft
