Crash Test Smarties

The Galle crater on Mars is also known as the Happy Face crater because of its appearance. First, scholars use pebbles and flour to simulate craters and study their properties. They then apply this knowledge to help decipher the history...

Open this lesson by demonstrating the production of acidic carbon dioxide gas by activated yeast. Emerging ecologists then experiment with seashells to discover the effect of ocean acidification on shelled marine organisms. They measure...

Create the universe on your laptop in just over five minutes! The video tutorial guides scholars step by step through the process of simulating the Millennium Run using Adobe After Effects. Watch as the narrator illustrates how density...

The camera flash works based on a simple circuit, but why does it require a capacitor? Scholars work through two levels of simulations related to circuits and capacitors. The pupils first use a simple circuit with a battery, resistor,...

The United States has more per capita emissions than any other country in the world. An eye-opening simulation encourages users to explore environmental goals and factors that affect climate change by balancing different priorities....

Does Newton's First Law of Motion explain how to move a sled across ice? A simulation encourages scholars to decide if they should push, pull, or apply no force. Their decision moves a sled across the ice and to the home at the...

How much pulling force does it take to overcome static friction? The simulation applies the formula for the force of static friction to multiple trials. Scholars alter the pulling force applied until the box moves. They then determine...

Solve the mystery of a declining frog population! Lead your junior ecologists on an investigation that simulates actual events concerning pollution, predation, poaching, and more. Investigators read a story online, then analyze survey...

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...

How can a magnifying glass or reading glasses make things appear larger? Scholars simulate moving a lens closer or farther from an object to observe the resulting image. They also alter the lens focal length. The simulation shows the...
