Strength in Size? Madagascar Cockroach Pulls
Fourth graders conduct an experiment involving size and relative ability in smaller species using Madagascar cockroaches. They make predictions about how many pennies the roaches can pull, compare the results to human strength, and...

Density and Buoyancy Lesson Plan
Young scholars investigate why some objects float or sink in water. In this physics lesson, students calculate the density of clay ball using a mathematical equation. They write a complete lab report about the experiment.

Graphical Determination of Density
Students determine the density of metal shot by a graphical method using significant digits in making measurements and calculations. Students graph a seris of laboratory measurements and determine density from a mass verses volume graph.

Teach Engineering: The Balancing Act
Students are given the opportunity to visualize and interact with concepts they have already learned, specifically algebraic equations and solving for unknown variables. Students construct a balancing seesaw system (LEGO Balance Scale)...
