SURVIVING A COSMIC INVASION

Ancient people used musical pipes as early as the third millennium BCE. Young scientists explore the workings of musical pipes to better understand the relationship with frequency, length of pipe, and sound waves. They determine the...

Sharpen up those scalpels, it's time to dissect some frogs! This step-by-step guide walks young biologists through this surgical process, helping them to identify major organs and unique anatomical characteristics of these amphibious...

We have formulas for finding the volume of geometric shapes, but what if the shape is irregular? Lesson describes how to find volume through water displacement. After a demonstration, scholars practice in small groups. Then analysis...

Friction and gravity are always at odds! Learners complete a set of activities to explore the relationship between friction and gravity. Groups make conclusions about the factors that affect the amount and type of friction between surfaces.

Shine some light on the topic of seasonal change with this collection of activities. Whether it's by measuring the change in the length of their shadows, or modeling the earth's orbit around the sun using a lamp and a globe, these simple...

How do you properly illustrate the extreme size difference between two planets—Earth and Jupiter? With the help of jellybeans, of course! Create a scale model of Jupiter's mass compared to Earth using a fishbowl, 1,400 beans, and a dixie...

The first life on Earth developed in the oceans. As an introduction to ecology, the video starts with the formation of the earth. It follows with the Archaean and Proterozoic Eons including protobionts, prokaryotes, and eukaryotes. It...

Eighth graders experiment with a Geiger counter and a dosimeter to test the amount of radiation in a room and the amount of radiation received in a day. In this radiation energy lesson plan, 8th graders test the shielding effect of...

Motivate young scientists to stand up and take action with this environmental science lesson. To begin, the class works in small groups brainstorming actions that support the conservation of the earth before creating and implementing an...

Do meteorologists and climate scientists use the same tools? The final lesson in a 13-part series on Exploring Energy compares and contrasts climate and weather. It describes the scientists who study each, the tools they use, their...
