Of quartz I love geology! The chapter offers five activities at three different levels. It features hands-on activities that cover crystal shapes, cleavage and fracture, hardness scale, specific gravity, and mineral...

This lesson certainly will not be a drag! Little engineers design parachutes that make use of air resistance and, as a result, slow the descent of the payload as much as possible. It is an opportunity to teach about many motion concepts:...

It's time to slow your roll! Can your class create a track that allows a marble to roll as slowly as possible? Teams of science scholars collaborate to design, build, and test their tubes while learning about gravity and friction.

Balloons aren't just for parties! An inquiry-based lesson explores the idea of using balloons for space exploration. Learners become engineers as they attempt to control the ascent and descent of a helium balloon using different masses.

In this geology course, students learn about the use of the polarizing microscope, the primary tool for examining the structure of mineral samples such as cleavage, density, fracture, color, and the like.

Hunkin's Experiments is a group of simple cartoon illustrations of scientific principles. Some would work well in the classroom, but others have little value beyond entertaining students. All of the projects are easy to do. This one...

Want to learn about rock collecting? This page introduces you to the basics and language of rocks and -inerals. Learn what the difference is between a rock and a mineral.
