This "lab-style" module helps students deduce and intuitively understand the formulae for volumes of prisms, and pyramids, cones, and spheres. Select each corresponding volume to find out more about them.
Squoosh Lab lets students "squoosh" or compress different volumes each into a unit cube. Students can then see the percentage of an object's volume to the cube's. (This was inspired by a similar Flash-based 2D module via the Annenberg CPB.)
Sum Lab lets students "slice up" each volume into smaller and smaller slices, to approximate their volumes numerically.
[Under Development] Slice Lab lets students observe corresponding 2D geometry that form from slicing each volume at different locations.
[Under Development] Drills - students can see 3D augmented reality versions of everyday objects such as soda cans and baseball's and calculate their volumes.
