We increased it by putting the balloon on our wheel and axle. It helped because it made our wheel and axle go further. It also helped because it made it go faster.

We increased the wheel and axle by something light like a paper cup. but it only went an inch. Our wheels were duck taped so that it never moved

Me and my partner were going to make the energy with both a rubber band and a balloon but it was to hard so we just stuck to doing it with a balloon. The balloon went fast but the wheels were not stabled. So it did not work but we tried.

We used a balloon straw and rubber band making lots of kinetic energy. We connected that stuff to our car propelling it but not that far. It was super hard!

My partner and I made kinetic energy by wrapping a balloon around a straw using a rubber band. You would blow the balloon and it would make the car move by blowing out air in the back. Other people used a rubber band and wrapped it around a tag on the tab that was on the car. But we had different options. And luckily my partner and I both wanted to do the balloon in the first place.

By using the ballons. When you put the straw into the ballon it goes the same derection thatis where the ballon is going. When you put the invention that we made it gives you more mass and that is how it is much harder. The things we made are 4 discs, 2 sharp straws, and play do. Well this was a fun day to do a wheel and axle.

The thing that increase the energy in your wheel and axle is that you need to make sure you do not make your wheel loose and make sure your rubber band is tape down tight. Also you need to try get the right kind of discs because if they do not roll properly then you have to get a different discs because the do not work! lastly you have to make sure you get the right kind of tools.

We were able to increase the kinetic energy by adding a balloon. We could also have a rubber band. The rubber band and balloon both had energy after you let them go. We used a rubber band in our wheel and axle.

We made the wheel and axle today and we made by wood,straw,CD disc, and the clay.It was so hard that we failed 3times.In the last try it worked!

Today me and my partner made a vehicle that was moved by a rubber band. The rubber band was connected to the wheels axle and then you rap the rubber band around the axle and then the car moves. And the wheels where made of C.D's.

My team made a rubber cart that wen' t one meter long.We used a rubber band that rapped around the scuer.when we released it wen' t a spec but the second time it wen' t one meter.

the thing that makes the kinetic energy stronger is wrapping the rubber band around many times and taping it down. Also it makes it go really fast. The other thing is that the wheels are secure

I think if thier was more room for the rubber band it would work but it didn't. :(

I was able to increase the amount of kinetic energy by using less weight of objects. I made a car with a rubber band to use engergy. I had fun !

We were able to use air to blow our vehicle.We also had to push it to move it.

I was able to increase the amount of kinetic energy by blowing up the balloon more. This worked because then the balloon has more potential energy stored up and when it starts to move it had more potential energy stored up so it has more kinetic energy later.

I increased the energy in my wheel + axle by adding a rubber band. When you stretch the rubber band it gets more potential energy and when you let go it gets kinetic energy. When it gets kinetic energy and it is spinning around the axle the wheel can move.
