Collisions

For Students 6th - 12th Standards
Is momentum conserved in a collision, along with energy, or are they opposing forces? Pupils vary the mass and velocity of two bumper cars along with the type of bumper in order to answer this question. Worksheet and in-simulator...

Bumper Cars

For Students 6th - 12th Standards
Is the transfer of energy different in bumper cars with stable versus bouncy bumpers? One of the variables explored in the simulation is bumper type; other variables are the mass and velocity of each car. This allows pupils to see the...

Crash Test Dummy

For Students 6th - 12th Standards
Why are car manufactures required to install seat belts and airbags; do they really make that big of a difference? Scholars use a simulator to determine the amount of force dissipated by a seat belt and airbag in a head-on crash. This is...

Life (and Fewer Deaths) After Seat Belts

For Teachers 7th - 12th Standards
Seat belts reduce serious crash-related injuries and deaths by about half. Scholars continue crashing their cart with a crash test dummy into a wall, but this time, they experiment with different types of seat belts to reduce injuries....

Train vs. Car: Who Wins?

For Teachers 9th
Ninth graders conduct an experiment demonstrating what happens when a train hits a car using easily accessible materials. They calculate momentum, velocity, and distance using the appropriate formulas. Then they write an incident report...
