In this activity, learners explore surgical instrument design. Teams of learners construct surgical instruments from everyday materials.

Learners follow directions to construct a water-powered electrical generator using a turbine made from plastic spoons.

Using recycled materials, learners will design a transportation vehicle to carry an egg in an egg toss (a rudimentary model of a shock absorbent transport vessel).

Cardboard Automata are a playful way to explore simple machine elements while creating a mechanical sculpture.

In this engineering/design/arts and crafts activity, learners design and build "platforms" or "bridges" that can hold weight, and test which glue makes the strongest structure.

This lesson focuses on two simple activities that younger learners can do to gain an appreciation of nanotechnology. First, learners measure their hands in nanometers.

This activity (on page 3 of the PDF under GPS: Body Electricity Activity) is a full inquiry investigation into conductivity.

In this activity, learners use a laser pointer and two small rotating mirrors to create a variety of fascinating patterns, which can be easily and dramatically projected on a wall or screen.

In this engineering design challenge, learners make a bird and then control its flight with attached strings.

This lesson focuses on graphene and its electrical properties and applications.

Learners create an electrical-circuit maze out of wire, then try to pass a paperclip through the maze without touching the wire.

In this outdoor activity, learners plan a simple foot path and create an environmental impact study of the natural area where the path would be.

In this activity, learners use microarray technology to determine which genes are turned on and off at various points in the differentiation of pluripotent stem cells on their way to becoming pancreat

In this activity, learners construct a simple air pressure launcher for paper rockets.

In this activity, learners simulate the separation techniques that materials recovery facilities (MRFs) use and then design their own series of recycling techniques.

In this activity, learners explore how engineering has developed various means to remove impurities from water.

In this activity on page 2 of the PDF, learners test different materials to find out which is the best insulator.

In this activity, learners design a scientific exploration mission to a planet or moon of their choice.

In this activity, learners use simple tools to build a bookshelf with a built-in bookend.

In this highly physical outdoor activity, learners construct and compare experimental trail sections to select the best trail-construction technique for their site.
