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

In this activity, learners investigate color vision as well as plan and conduct their own experiments.

In this two-day activity (on pages 16-22), learners use a process like that of the Yoruba people of Nigeria to create an African symbol on cloth.

This marine biology activity (on pages 11-17) introduces learners to kelp (seaweed) forests that grow in the ocean and are home to many species of sea animals.

Learners trace, cut out and fly a boomerang, outdoors or in a large indoor space.

In this activity, learners create a traditional Mexican noisemaker (a matraca) using cardboard, craft sticks, and a wooden dowel.

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 get hands-on experience with ratios and scaling while making their own jewelry out of recycled plastic containers.

In this art meets science activity, learners pack silver, ball-shaped ornaments in a single layer in a box to create an array of spherical reflectors.

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

In this activity, learners create three-dimensional shapes by making some origami models of simple boxes and containers.

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

In this engineering design challenge, learners animate a facial expression and make a machine (zoetrope) that plays the animation back.

Use a Pico Cricket (micro-controller) to animate your art! You can program a Pico Cricket to make your art spin, light up, or make music.

In this activity, learners of all ages will experiment with paint and printmaking.

Make a rattle-like musical instrument! Shake it, hit it, spin it any way you want to!

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 activity, learners discuss and investigate how cameras, telescopes, and their own eyes use light in similar ways.

In this activity, learners simulate what happens to a human spine in space by making Sponge Spool Spines (alternating sponge pieces and spools threaded on a pipe cleaner).

In this lesson, learners develop a robot arm using common materials. Learners explore design, construction, and teamwork, as well as materials selection and use.
