Students utilize triangulation techniques to determine altitudes of objects. An altitude locator is constructed and used to determine the height of a building or a tree. Tangent tables and formulas provide the ratio for the formula to...

Explore the geometry of treasure hunting! Learners use geometry to design a treasure recovery strategy. The objective is to create a design that minimizes the amount of work required. Budding mathematicians use properties of triangles as...

Students investigate ways to enhance an object's flying ability.  In this model construction lesson, students construct two paper airplanes, one of which is twice as big as the first.  Students compare and contrast the two...

In this calculating the horizon worksheet, students solve 6 problems using algebra, derivatives and calculus to find the formula for the line-of-sight horizon, the distance along a planet, the horizon distance and the rates of change for...

Students study the history of kites and their fundamental properties.  In this kites lesson plan students divide into teams and build and fly kites. 

Students simulate the Earth's revolution around the sun using CEENBoT. In this earth science activity students calculate the Earth's distance in AU and it's speed of revolution. They explain how the Earth's movement cause seasonal...
