Sixth graders measure circumference and diameter to the nearest eighth of an inch, record measurements on a spreadsheet, and use the internet to complete a "scavenger hunt" of facts concerning pi.

Students explain the advantages of nanotechnology. For this chemistry lesson, students investigate pretzels' average diameter and circumference. They graph their result and compare with other groups.

Clamp onto the resource and don't let go. Future mechanical engineers produce a pipe clamp from a sheet of metal. This idea is to use the pipe clamp to affix a pull-up bar in a doorway.

Fifth graders review EOG math terms and definitions found in their math notebooks, and pick between 15 and 20 words to put in a word search.
