How Can We Find Out What Is in Water?
Using paper chromatography, water watchers discover that several substances might be dissolved even though they aren't visible. For this case, you will prepare a mixture of three different food colorings for them to experiment with. A...

Constructing and Visualizing Topographic Profiles
Militaries throughout history have used topography information to plan strategies, yet many pupils today don't understand it. Scholars use Legos and a contour gauge to understand how to construct and visualize topographic profiles. This...
