Title: Rubber band 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…. To make it look like a sail boat. (that’s why there’s a sail.

 

I believe my original design will allow the boat to stay afloat and move through the water because… It has many things to keep it where it is. Popsicle sticks, rubber bands, etc.

 

When I put my boat in the water tub this is what happened: It fell over…

 

The changes I am going to make to improve my boat design are… Flat surface 

 

My re-built boat:

I believe my new design will allow the boat to stay afloat and move through the water better because… It has a rubber band.

 

When I put my newly designed boat in the water tub this is what happened…. It floated and did a good job.

 

Some more improvements I could make to my boat are…. Make it better by putting more effort into it.

 

This challenge was comfortable because… It was really fun

 

This challenge was difficult because… It was hard because it was powered by a rubber band.

 

This taught me about potential and kinetic energy because… It had the rubber band.
