How well did the racer work?  Did it go far?  Did it go fast?

The racer went pretty far for just a spool and rubber bands. It didn’t go that fast but I went the farthest in the class. But it worked and I didn’t think it would work or go far.

What aspects of your design are working?

When we tested the racer all of the aspects worked except for when we rolled the rubber bands they got in the way of the racer moving.

What aspects of your design are not working?

When we rolled the rubber band around the Spool.The rubber bands got in the way of the wheels turn in that slowed down the racer.

What questions do you have?

Ome question I had was how can we roll up the rubber bands in a way that the don’t get in the way of the weels don’t get in the way.

How will you adjust your design?

Maybe I’ll can shorting the rubber nbands so they don’t get in the way of the weels.

How will you build your racer? We will build our racer by putting rubber bands around the spool then taping it down so it is secure. Then we will wrap the rubber bands around the spool so it can go forward.
What materials will you use?

• Rubber bands
• 1 Spool
• Duck Tape
• String
  What ideas do you have at this point to make your racer go the fastest and the farthest?

We are going to use a spool so it can go faster.

• What questions do you have?
• If we pull the rubber bands then will it still mean that the rubber bands are controlling it ?
