| C.J. secures his passengers carefully. |
|
 |
 |
| Time to
go, little guys. |
|
 |
|
| Hopefully
these two didn't see it coming. |

 |
| Jacob
prepares his passengers for their trip, who mercifully didn't see what
happened to C.J.'s little friends... |
|
 |
 |
 |
|
| Well, at
least they stayed in the vehicle. |

 |
| Nathan
tries a different twist on the seatbelts in his vehicle. |
|
 |
Students
learned that faster cars hit the wall with more force and without
seatbelts, the egg passengers continued to go forward after the vehicle
stopped. (Newton's Law of Motion). They learned that the purpose
of a vehicle's bumper is to absorb some of the shock of a collision. |

 |
| Trent
picks up the pieces after sending his two passengers down the "ramp of
no return". |
|
 |
 |
| Adam
puts the final touches on his passenger's seatbelts and cushioning, as
classmates offer their advice. |
|
 |
Adam's passengers actually survived their trip. |
|
This experiment helped students
gain an understanding
of kinetic and potential energy and utilized
several formulas such as F = ma (Force = mass * acceleration) and W =
mg (Weight = mass * gravity). Students learned that engineers use
these principles in real life applications to design and test cars and
seatbelts for safety purposes.
