Projections and Coordinates: Turning a 3D Earth into Flatlands
Introduce your class to map projections and coordinates, the basics for the work done in a GIS, with an activity that uses Google Earth to challenge learners to think about the earth's shape.
Teach Engineering
Quantum Dots and Colors
Introduce teams to quantum dot solutions with an activity that has them expose solutions to a blacklight, observe the colors, and take measurements. Groups graph the data and analyze the dependence between particle size and color...

Superhydrophobicity – The Lotus Effect
Discover and demonstrate the Lotus Effect and superhydrophobic surfaces with the eighth installment of a nine-part series that teaches scholars about surfaces that exhibit superhydrophobicity. The lesson continues also describes...
Teach Engineering
Exploring the Lotus Effect
The Lotus Effect ... is it not some kind of yoga pose. In the last installment of a nine-part series, young scientists observe the Lotus Effect on lotus leaves and water-repellent cloths. They observe how motion and damage affect the...
Teach Engineering
Forms of Linear Equations
Linear equations are all about form. The fifth part in a unit of nine works with the different equivalent forms of linear equations. Class members become familiar with each form by identifying key aspects, graphing, and converting from...
