Cushioning Collisions (Computer Analysis)
Did you know the car bumper is specifically designed to save the car and not the passengers in case of an accident? Young scientists use a computer, a force probe, and a sonic ranger to experiment with external cushioning on cars.

Concentrating on Collisions
How important is momentum? Pupils investigate and apply the definition of momentum as they conduct analyses during a series of one-dimensional collisions. They infer the relative masses of two objects by carefully staging and predicting...

The Rear End Collision
Did you know one in every four car crashes are rear end collisions? The lesson explains what happens to your neck when you are involved in a rear end collision. Scholars experiment and apply Newton's Second Law of Motion.

Conservation of Momentum: Marble Collisions
What happens to the momentum of an object when it strikes another object? Scholars roll a marble down a ramp so it collides with another marble. By measuring the speed of each marble before and after the collision, pupils answer this...

Egg Drop
How do different shapes affect the outcome associated with hard impact? All you need is an egg and some recycled materials to find out. Kids experiment to understand how airbags work to lessen the impact of two different types of...

Life (and Fewer Deaths) After Seat Belts
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....

Life (and Death) Before Seat Belts
Did you know only 80-90% of passengers wear a seat belt in a moving car? Young scholars use clay and a cart to complete an experiment about what happens without a seat belt in a collision. The lesson includes Newton's Second Law of...

Sensors in Chemistry
The Environmental Protection Agency monitors sensors to track air pollution and set clean air standards. Enthusiastic young scientists use similar sensors to gather data in their area and then apply the gas laws and conservation of...

Action-Reaction Lab
Computer-interfaced motion detectors are required to carry out this inquiry. It is a new twist on exploring motion with plunger carts: they are set back-to-back and then propelled away from each other. Their velocities are measured, and...
