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!

Discover geometry by creating shapes from loops of paper. In this activity, paper loops transform to give you totally new structures when you cut them.

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

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.

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.

In this math lesson, learners use the setting of a flower-making fundraiser to explore a variety of patterns. Learners examine the patterns in a flower design made of triangles surrounding a square.

In this activity, learners explore how casts of fossilized bones are created and used to learn about dinosaurs. Learners make observations, draw diagrams and share their findings.

In this activity on page 2 of the PDF, learners discover how color changes can help scientists distinguish between acids and bases.

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

In this activity, learners create a colorful bookmark using a super thin layer of nail polish on water. Learners discover that a thin film creates iridescent, rainbow colors.

In this activity, learners will build a model of a nebula using cotton balls and colored water. Astronomers photograph nebulas and add colors to provide information about the nebula's composition.

Align four color transparencies, each one a single color (cyan, magenta, yellow, and black), and see a beautiful full color image.

In this activity, learners make their own bug boxes and test the habitat preference of selected "minibeasts" (bugs).

In this activity on page 3 of the PDF, learners discover how science and Halloween are fun companions as they make paper bleed.

In this activity, learners make a paper model of a polymer, then make Silly Putty, an actual polymer.
