In this activity about molecular diffusion (located on page 2 of the PDF under Nanosilver Activity), learners will make predictions and move molecules of iodine through a seemingly solid plastic sandw

This is an activity (located on page 3 of PDF under Gecko Feet Activity) about modeling a nanoscale phenomenon (gravity-defying gecko feet) with macroscale objects (shoes).

In this design challenge activity, learners invent a pinball-like game where a kick stick hits a ping pong ball into a target that buzzes.

This activity shows learners how computers use numbers to represent pictures. A grid is used to represent the pixels (short for picture elements) of a computer screen.

In this activity, learners explore how engineers have improved roofing designs and materials in order to protect the contents of buildings.

In this activity, learners design, build, test and redesign a display tower that will meet a specific set of criteria and constraints.

In this activity about encryption, learners cut out a secret decoder badge from a handout and use it to encode messages to each other.

This is an activity (located on page 3 of the PDF under Self-Assembly Activity) about self-assembly, the ability of molecules to assemble themselves according to certain rules.

In this activity (located on page 6 of the PDF), learners explore the ways people access water in their homes.

In this sports-themed engineering activity, learners create super bouncy balls out of balloons. Learners brainstorm, test their designs, and share results.

In this activity, learners work individually to assemble a product and then work in teams to design, construct, test, and redesign an assembly line process whose product must meet specific quality con

In this interdisciplinary activity, learners create a Space Weather Action Center (SWAC) to monitor solar storms and develop real SWAC news reports.

In this series of activities (page 5), students are introduced to the design process.

In this water activity, learners discover ways to move water across the water table.

The purpose of this plant biotechnology activity is to demonstrate the effect of changes in the environment on the growth and fertility of landscape grasses and crop grasses such as wheat and rice.

In this three/four-day lesson, learners calculate perimeters and areas and draw the castle plan to scale.

In this design challenge activity, learners make a balloon hover at eye level for five seconds, and then make it move by creating air currents.

In this activity (page 12), learners apply the concepts of pixilation and pointillism to the world of biomedical science.

In this environmental engineering activity, learners build windmills using everyday items. The first challenge is to build windmills that spin when placed in front of a fan.

In this activity on page 13 of the PDF, learners use a laser pointer (with known wavelength of light) to measure the thickness of a human hair.
