In this activity, learners construct a projector out of cardboard to view their favorite images (such as storybook illustrations) on the wall.

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

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.

In this activity, learners observe and describe the physical and behavioral characteristics of insects, including crickets.

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.

Build your own version of a favorite carnival game, in which a marble races down a maze consisting of rows of nails.

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

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

In this activity about heart health (on page 27 of the PDF), learners measure their heart rates after a variety of physical activities and compare the results with their resting heart rates, and with

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 activity, learners construct a device that projects images onto a surface, so they can trace landscapes and other sights.

In this activity on page 4 of the PDF (Behind the Scenes with Chemistry), learners make some special effects, including snow and breaking glass, with supplies found in the home.

In this chemistry activity which should only be done under adult supervision (page 10 of the PDF), learners will create an exothermic process by making Sodium Acetate.

In this activity, learners will test cups full of potting soil, sand, and sphagnum moss to see which earth material is able to soak up the most water.

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

In this hands-on art and science activity (page 4 of the pdf), learners brainstorm and discuss how humans use wetlands, then express their understanding of the subject in artwork.

In this activity on page 5 of the PDF (Plants—The Green Machines), learners use chromatography to separate and identify pigments within various leaves.

In this activity, learners will observe a deceptively simple process: a burning candle.

In this activity, learners construct a model of DNA to better understand the structure of DNA and protein synthesis.
