In this activity, learners build a carousel toy that spins when pushed down.

In this activity, learners discover that nanoparticles of gold can appear red, orange or even blue. They learn that a material can act differently when it’s nanometer-sized.

In this activity on page 11 of the PDF, learners use candle wax to make "invisible" designs that are revealed with watercolor paints.

In this two part activity, learners become draft detectives by constructing their own draft catchers to detect drafts around windows or doors.

This great "re-use it" activity will demonstrate how to transform a greeting card into a box. Once constructed, the box can have many uses like holding special notes or keepsakes.

In this design challenge, learners will engineer a structure and see if it can survive an earthquake they create.

In this activity, learners build a machine made of craft sticks to multiply the levering motion of their hands and create a device that bends and extends.

In this activity, learners construct a simple game to test their hand-eye coordination and steadiness of hand.

In this up-cycling activity, learners recycle plastic bags and repurpose them into useful wallets.

In this activity, learners will become an engineer by designing and engineering a miniature parachute.

This is a quick activity (on page 2 of the PDF under Butterfly Wings Activity) that illustrates how nanoscale structures, so small they're practically invisible, can produce visible/colorful effects.

This resource contains ideas and brief instructions on how to build animals out of construction paper and other simple materials.

In this activity related to nanotechnology, learners observe some of the effects that result from creating a thin layer of material several nanometers thick.

In this great hands-on activity, learners use patterns to make a teepee from newspaper that they sit inside.

In this activity, learners will build the highest tower they can out of recycled materials.

In this activity, learners explore the properties of paper by constructing and modifying paper airplanes.

In this activity, learners use clear nail polish to create a beautiful iridescent pattern on black paper. Learners discover that a thin film creates iridescent, rainbow colors.

In this activity, learners use a nail and magnet wire to build an electromagnet, which controls the movements of a paper dancer.

In this activity (page 95 of the PDF), learners create Escher Staircase models similar to those that were used by Neurolab's Spatial Orientation Team to investigate the processing of information about

In this activity, learners build a bird that flies in place with help from a motor, wire, and some straws.
