Newton's Law of Universal Gravitation
While science is looking for correct explanations, pseudoscience often fills in the blanks. Pupils explore the relationship between light distance and intensity and graph their data. Then they compare their data to Newton's Law of...

Force Fields
Young scholars investigate both bar and horseshoe magnets. They explore force fields with a compass and iron fillings before making an electromagnet. This is the first in a series of nine lessons.

You Are What You Eat: Testing for Organic Compounds in Foods
We have all heard that we are what you eat, but what are we eating? An informative lesson opens with a discussion of the foods pupils have recently eaten. Then, young scientists perform four experiments on seven different foods to...

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.

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.

Automatic Triggering Devices
How does the air bag trigger in an accident? The lesson explores how automatic triggering devices work in automobiles. Using examples such as a seat belt lock and air bag, scholars design their own device to better understand the...

Why Air Bags?
If a heavy steel car can't protect you from injury, how can a bag filled with air? The lesson answers this question and many others as young scientists experiment with the impulse and forces related to air bags in automobiles.

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...

Speed and Following Distance
How much distance should you keep between your car and the one in front of you? Did you think of an answer in terms of time when the question clearly stated distance? The lesson covers the relationship between distance, time, and speed....

What’s the Problem with Isotropy?
Some patterns are so small, we can't see them without the help of technology. The same is true for cosmic microwave background radiation. During this activity and discussion, scholars examine both anisotropic and isotropic items and...

Solution Concentrations
What happens when you combine 6.022 times 10 to the 23 piles of dirt into one? You make a mountain out of a mole hill. Scholars use dehydration to obtain percent composition and then calculate the molarity of the original solution.

Molar Volume of a Gas
What is a chemist's favorite plant? Stoichiome Tree! Scholars produce hydrogen gas by reacting magnesium with hydrochloric acid. Then they calculate the molar volume of the gas produced before answering assessment questions.
