In this design challenge, learners build a boat that paddles itself using a rubber band as its power source.

This is an activity (located on page 3 of the PDF under Nanosilver Activity) about diffusion of small molecules across cell membranes.

In this activity, learners build bridges using paper and explore how much weight each bridge design can support.

In this activity, learners design miniature cars. Learners can create a telephone car, soccer car, merry-go-round car, or any other theme car they can imagine.

In this activity, learners build bridges and cantilevers in a series of "building out" challenges with straws and pins.

In this activity, learners create a model of a hot air balloon using tissue paper and a hairdryer. Educators can use this activity to introduce learners to density and its role in why things float.

This activity (located on page 3 of the PDF) is a full inquiry investigation into mapping the underground “plumbing” of geysers.

In this activity, learners construct paper airplanes that twist and turn.

Create airplanes from straws and geometric shapes. Test them out to see how far they can fly, or how accurately they can be aimed.

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

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

In this activity on page 3 of the PDF, learners visualize the relative size and structural differences between microbes that have the potential to cause disease.

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

This activity is a hit for family events and all ages—some will finish in 45 minutes; others can go on for hours.

In this activity, learners explore work, forces, simple machines, and construction. This lesson guide includes simple ways to demonstrate these principles as well as hands-on activities.

In this team design challenge (page 2-10 of PDF), learners design and build a model of a Lunar Transport Rover that will carry equipment and people on the surface of the Moon.

In this activity, learners explore how the process of folding has impacts on engineering and is evident in nature.

In this activity, learners simulate nature's water filtration system by devising a system that will filter out both visible and invisible pollutants from water.

In this activity, learners make a scale model of an atom to see how big or how small an atom is compared to its nucleus. Learners will realize that most of matter is just empty space!

Working in small teams, learners try to build a satellite that can float for at least five seconds in the marked area of a vertical wind tube.
