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 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 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 math activity, learners read "The Button Box" by Margarette S. Reid and then make their own button boxes filled with different buttons.

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

In this activity, learners explore the factors that tend to resist changes in pH of the ocean and why the ocean is becoming more acidic.

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 construct three math puzzles out of simple materials like wood, string, and Styrofoam.

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

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.

Learners will follow a specific process to make their own paper using scrap paper, newspaper, or junk mail.

Make a one-string "guitar" by stringing a cup with some fishing line. You amplify the plucking of the string by placing a piezo contact microphone and mini battery powered amplifier inside the cup.

In this activity, learners explore how environmental engineers might approach solving the problem of an oil spill.

In this activity, learners repeat patterns in two and three dimensions to create tessellations.

In this technology activity, learners light up the room with electrifying play dough creations. Learners use conductive and insulating homemade play dough to build simple circuits.

In this activity, learners design unique tiles and make repeating patterns to create tessellations. This activity combines the creativity of an art project with the challenge of solving a puzzle.
