A mouse can fall from large heights without injury! Air resistance is a large influence on small falling objects. In an exploratory lesson, young scholars build a raindrop bottle to compare the falling rate of different-sized objects.

Over the course of 10 days, young scientists observe their cups of seed and soil—one that gets sun and water and one that gets no sun and only water. Then they reflect on the results of the experiment to determine if their hypothesis was...

Make works of art using a vintage yet effective etching strategy. The surface of a semiconductor chip has specific patterns formed through a process called etching. Through a lab investigation, young scholars recreate that process...

Step-by-step instructions, with photos, of how to prepare an egg for a 'bungee jump' using a plastic bag and elastics, and a yard stick to measure the distance it falls each time it is dropped. The activity investigates the Law of...

Create a traditional instrument called a rainstick in this activity.

A collection of mechanics activities. Many pertain to Newton's laws of motion. Step-by-step directions provided with illustrations. Great for teacher demos or student projects.

In this experiment, students build and calibrate a rain gauge and use it to measure and record how much rain falls in their local area each time it rains.

In this activity, pour a salt-sand mixture into a CD case to notice how the particles separate themselves. Observe the effect known as granular convection as the smaller sand particles fall beneath the larger particles leaving a layered...

An activity exploring eddy currents by having a magnet fall through a metallic and nonmetallic tube.
