This is an intriguing problem that brings together real-world data, technology, and mathematical problem solving. If visibility wasn't an issue, could you see from the highest point in the lower 48 states, Mt. Whitney, to the lowest...

Students shoot off a rocket and measure the trig ratios relation. In this geometry lesson, students practice using an inclinometer to figure out how high their rockets fly. They measure angles and height and relate it to gravity and...

Students investigate the properties and idea of the Pythagorean Theorem. In this algebra activity, students identify the different parts of a right triangle and relate it to the Pythagorean Theorem. They do a robotic experiment to...

Students create sets of similar triangles which, when fixed together with a piece of Scotch tape, form a spiral-like, segmented shape, slightly similar to the cross section of the shell of a nautilus.
