Does increasing the pressure between two moving plates provide a stabilizing force or create more destruction? The hands-on lesson encourages exploration of strike-split fault models. The sixth lesson in a 20-part series asks...

Bridges rely on tension and compression to keep them standing. Pairs test this principle by constructing simple bridges and applying a force to the center. Teams use the provided worksheet to record their observations of the...

How does the Earth continually repair itself? Explore the answer to this question, and others, with a unit on plate boundaries and interaction. Pupils classify the types of movement at plate boundaries and identify the...

Silver: more than jewelry, it's also a natural antimicrobial agent. An inquiry-based lesson asks collaborative groups to design and implement an experiment to test this property. Using samples of silver nanoparticles and a strain of...

How many visual models can be used to show multiplication? Three basic kinds of models can be used to represent and explain the equation 4 x (9 + 2).  The commentary section provides description and graphics to explain the set...

Feel like a rocket scientist for the day. Using only paper and tape, scholars create a framework for a spaceship to Mars. Each sheet of paper costs $10 million and each piece of tape costs $100,000. Make sure you stay within budget!

Just because we can't see it doesn't mean it isn't there! A growing concern for environmental scientists is toxic nanoparticles in our air and water. Young scholars conduct an experiment to demonstrate how these particles can cross our...

A short activity that focuses on the normal distribution as a model for data distribution. Using given means and standard deviations, your budding statisticians can use statistical tables, calculators, or other statistical software to...
