Penny Perfect Properties (Solid-Liquid Interations)
I can get more water to stay on a penny than you can! Collaborative pairs determine the volume of liquids that can be contained on the surface of copper pennies and plastic coins. The pairs analyze their results using graphs and go on to...

Water Quality Assessment
Students evaluate water quality of different sources. In this water assessment lesson students chemical testing, identify biological factors in the stream, and write a paper on their position of the stream's quality.

Capturing the Wind
Students collect and analyze data about wind speed. They build a Lego wind sail and measure the wind speed with a rotation sensor. They use software to analyze the data.

Teach Engineering: Penny Perfect Properties (Solid Liquid Interactions)
Students investigate the property dependence between liquid and solid interfaces and determine observable differences in how liquids react to different solid surfaces. They compare copper pennies and plastic "coins" as the two test...
