Here is what I learned during our study of Structures and Mechanisms .This is our bridge that tied for third. I thought we could have put in supporters so it could hold more weight.we made beams to hold it up. the force on the bridge pushed it down. we could have put supporting polls on and it holds more weight.

We made sure that our house can hold hevy forces. We made a suppoting wall to hold the forces. The beam we made in the roof made a big difference to because it made the force go to the supporting wall. We could have put more beams under the roof.

 * To make a football you need cow hide. You get cow hide from cows that have died. You need to give the cow skin to a tanner. That's how you turn it in to leather. Inside the leather, there is a rubber blatter. They get the rubber from para rubber trees in Brazil. The sap from the tree gets used to make the rubber. They must have to wait until it drys and try to mold it.**

=This is our energy exparement.= We conducted experiments into the transformation of energy. I learned how to make a can roll back with energy. First, you push it using kinetic energy. While it's rolling, an elastic winds up using elastis energy. Then, using kinetic energy, it starts rolling back. Finally, when the can stops rolling, all the elastic energy transforms into heat and sound.
