Seventh graders become museum conservators and undertake the hypothetical restoration of an ancient American work of art. Groups design a plan for reconstructing the work of art, outlining the steps they need to take and the materials...

An ancient puzzle game meets a modern implementation. Challenge mathematicians of all ages with this mind-bending geometric puzzle game. 

Students explore local, state, and national levels of government and discuss which level of government they should contact to get information, express their opinions, or get help on specific issues.

Parallelograms are pairs of triangles all the way around. Pupils measure to determine the area and perimeter of a parallelogram. They then find the area of the tirangles formed by drawing a diagonal of the parallelogram and compare their...

Sixth graders discover the problems that early Mesototamian farmers faced while developing agriculture in the land between the Tigris and Euphrates Rivers. They design a working model that solves those unique challenges.

Students explore motion by observing the movement of people and duplicating those movements. They compare and contrast various kinds of movements and identify different types of movements in pictures. They build an object that can be...

Rescue animals in the zoo by applying math concepts. Groups of learners solve three missions involving oxygen, food, and climate control. Each group selects an animal from one of four bio-domes.

Students listen to clips from Congressional Moments radio programs to examine role government plays in our lives, and discuss role of citizens in a representative democracy.

High Schoolers complete a variety of activities as they examine the ethics of (and take a position concerning) genetically modified organisms in the field of agriculture. They complete a PowerPoint demonstration to go along with the unit.
