Students calculate ppm and ppb by using unit analysis when given a ratio of amounts. They determine in ppm what constitutes a health risk for a particular toxin given data and whether local health officials should close a lake...

Ninth graders are presented with a problem that has to be solved. The scenario is a mystery that is purely hypothetical. This does draw on the knowledge of previous lessons. The lesson plan contains background knowledge explaining the...

Students plan a trip.  In this trip planning lesson, students use a map to find where they would like to visit with a pretend family of 4. They get a specific amount of money and time and need to decide where they will stay and what...

Learners construct three-dimensional models of the three pyramids at Giza. They research the building of the pyramids and record the height, base and angle measurements of each pyramid. They create a file of facts regarding the pyramids.

Students calculate the distance in light years. In this geometry lesson, students solve problems involving distance, using the distance formula. They rewrite big numbers using scientific notations and apply their knowledge of everyday...

Young scholars explore tornadoes, the damage they cause, and how to rate tornadoes. They will investigate the Fujita Damage Scale of tornado intensity, and use it to complete a mock engineering analysis of damage caused by a tornado....

High schoolers explore the concept of quadrilaterals as they find the midsegments of quadrilaterals using Cabri Jr. on a graphing calculator. They find midpoints, slopes, angles, and distances of lines and angles.

Learners define the term species, and graph species data together with previously collected data at the National Zoo. They interpret graphed data and recognize patterns in the streamside quadrant versus hillside quadrant. Students use...

High schoolers construct perpendicular bisectors using Cabri Jr. on their graphing calculator. They then construct conditional statements about perpendicular bisectors along with their converse, inverse, and contrapositive.
