In this geometry lesson on cylinders, geometers explore how to find the smallest surface area for a given volume.  They use their knowledge to relate it to the real world by making a model of a livestock tank.

Students draw a net (a two-dimensional pattern that can be formed to make a solid) for making an open top box on grid paper. They cut out the net and fold up each side to form the open box and tape the sides, then find the volume of the...

Students analyze the amount of space required to pack round objects. In this geometry lesson, students practice using space economically by practicing packing spheres into beakers. They then translate this concept to molecules being...

Middle schoolers create and give oral proposals for the construction of a gazebo using a blueprint created with Geometer's Sketchpad. They then build a gazebo model using the blueprints created and provide evidence why it should be...

Young scholars create jewelry from junk mail. In this visual art activity, students use junk mail to design necklaces and bracelets.
