Students compare and order numbers. In this geometry lesson plan, students write equations for inequalities. They differentiate and apply concepts of triangular properties to solve problems.

Students perform operation with secant and tangent lines. In this calculus lesson, students find the derivative and relate it to the slope of a line. They differentiate between secant and tangent as they intersect a circle, using Cabri.

Students study yeasts or cellular respiration in this inquiry activity. They examine different types of bread to show which rise or do not. They measure the amount of carbon dioxide released by the yeasts when using different sweeteners.

Students observe two chelae. They write three differences they observe in their notebooks. Students suggest a hypothesis which would explain these differences. They dissect the chela. Students analyze the lobster claw as a mechanical lever.

Middle schoolers determine their own walking and running velocity. In this physics lesson, students calculate velocity using distance and time information. They compare human and animal speeds.

High schoolers use their knowledge of DNA fingerprinting to evaluate the use fingerprints in courts, and will address the ethics of establishing a national database of fingerprints.

Students explore DNA fingerprinting. Students discover how DNA fingerprinting is done and judge the validity. They evaluate the use of certain prints in courts and address the ethics of establishing a national database of fingerprpints.

Students explore the physical properties of density. In this hands-on lesson, students calculate density and distinguish between intensive and extensive properties.

Students compare the anatomy of a fish to an amphibian and that of an amphibian (frog) to a human. They complete a virtual frog dissection to gain some experience prior to the real dissection.
