Weathering Rocks

In this lab, the student will investigate the weathering of rocks, both physically and chemically.  The students should have an introductory lesson on how rocks go through changes.  The students should also understand the difference between a physical and chemical change.

Twisting Tornado

In this lab, the student will create an example of a vortex by applying the concept to a tornado in a jar.

Magic Crystals

In this lab, the student will create their own crystals and possibly eat them too.  Learn the lattice structure of crystals and make a time-lapse video.

Eclipses and Shadows

In this lab, the student will see how the movement of the sun and moon relate to a solar and lunar eclipse.  In this case, the sun will be a handheld flashlight or a mounted wall light, the moon will be a small Styrofoam ball and the Earth will be a larger Styrofoam ball.

Copper Sulfate Crystallization

Expand the minds of students by growing copper sulfate crystals for a time-lapse recording that the students will experience right before their eyes with a digital microscope. In this lab, crystallization occurs by heating water and dissolving copper sulfate into a saturated solution.  When the temperature of the saturated solution begins to lower, crystals will begin to form.
