Group 1(Drew, Haley, Hunter, Edgar, Adam)

**Diagram:**


=**Description:**=

A. Hunter uses the remote control to send an electromagnetic signal to the car. B. The car hits a wooden ball down the ramp, increasing its kinetic energy. C. The ball hits some Newton balls and increases their kinetic energy. D. The last Newton ball hits a set of dominoes, increasing their kinetic energy, and pushing them forward. E.The dominoes hit another wooden ball, causing and increase in kinetic energy and pushing down a ramp. F. The wooden ball hits a pink ball turning potential energy to kinetic and knocking it forward. G. The pink ball hits the paper wad turning potential energy to kinetic. H. The paper wad’s kinetic energy increases and it falls into the trash can.

Steps-

=
Strike a match, which burns the string that is attached to the car. The car then rolls down the track that knocks dominoes. The dominoes then push the ball down the slide. The ball goes into the first cup. Next the second cup is lifted up. The three balls under the cup are released. Lastly the balls knock the paper wad into the trash can. =====

=
First energy was thermal energy with the match burning the string; second energy was kinetic energy with the car rolling down the ramp, third energy was kinetic and potential energy when the dominoes were knocked over, fourth energy was kinetic and potential energy when the ball rolled down the slide, fifth energy was potential when the ball fell into the cup, and sixth energy was potential and kinetic when the three balls rolled down. ===== Insert video here:

=**Description**=

A: Hannah pulls a stool that is tied to a stack of books. B: The books fell. C: The rock fell to the table. D: The seesaw went up. E: The marble rolled down the seesaw, into the ramp. F: The marble jumped off the ramp. G: The marble hit the paper wad. H: The paper wad entered the trashcan. Success!

Insert description here: Our project started with a marble on a ramp. We dropped a marble down the ramp and it fell off, hitting a lego block. The lego block acted as a see-saw, which hit another, and another. Then, it hit a lego block with a block on it. The block fell in a cup attached to a string. The string pulled up another lego with a paper wad on it. The paper wad fell in a bowl that had a whole in it. The paper wad fell in the whole and into the trash can, fulfilling our task. As for the energy present in our project, first, the marble had potential energy, then, the marble had kinetic energy as it went down the ramp. The legos had potential energy which then changed to kinetic when hit by the marble. The block had potential energy until the legos pushed the block into the cup. Then, the cup switched from potential to kinetic when pushed down. Same with the lego. Lastly, the ball switched from potential to kinetic when hit by the lego, thus sending it into the trash can.
