Discover a world too small to see. In the lesson, young scientists learn about nanotechnology and brainstorm ideas for new applications of it. They perform an activity to determine how surface area changes when objects are made smaller...

Learners find the volume and surface area of a rectangular box (e.g., a cereal box), and then figure out how to convert that box into a new, cubical box having the same volume as the original. As they construct the new, cube-shaped box...

Be sure to use this sweet resource. Scholars perform an experiment using sugar to investigate how surface area relates to the coarseness of sugar. They consider how this concept connects to nanotechnology.

Create a geometric playground. Pupils work through a performance task to demonstrate their ability to use geometric concepts to solve everyday problems. The accompanying engineering design lessons show teachers how the assessment works...

Boxing takes on a whole new meaning! The second installment of the three-part series has groups create lidless boxes from construction paper that can hold the most rice. After testing out their constructions, they build a new box....

Pupils create a spreadsheet that calculate the amount of concrete needed to pour various concrete forms.
