Experiment with friction and make bearings for a whirligig! This activity is a nice introduction to friction and bearings and demonstrates why bearings are useful for spinning.

In this activity, learners explore sound by constructing a simple piano out of wood and craft sticks.

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 playful, goopy activity, learners mix two liquids to create a solid (that sometimes acts like a liquid ), using basic household materials such as borax and glue.

In this activity, learners build a figure that moves and "comes to life" when they pull its string.

In this activity, learners create handmade animal track stamps. Learners research animal tracks, draw the shapes on moleskin, and then stick the shapes onto blocks of wood to make stamps.

In this activity, learners build their own sound machines and explore the interplay of motion and sound.

In this simple and fun activity, learners discover the relationship between vibration and sound by making a squeaky toy instrument out of simple household materials.

In this activity, learners use transparent tape and polarizing material to create and project beautifully colored patterns reminiscent of abstract or geometric stained glass windows--no glass required

In this activity, learners arrange triangles together to make patterns to create paper quilts. Learners experiment with arranging the triangles in different ways to make various designs.

This is a simple activity for learners to create a traditional musical instrument. Pan Pipes have developed all over the world in different cultures, from South America to Greece and China.

Build time sense into the schedule by asking learners to predict what can happen in a certain amount of time: We have 20 minutes before outdoor time. What can you get done?

In this activity, learners create their own icons for a forecast-at-a-glance poster for their classroom/learning space.

This activity introduces learners to the structure and properties of carbon nanotubes.

In this activity, learners build a musical drum using a cardboard tube, plastic wrap, and beads.

In this outdoor science/art activity, learners investigate spider webs by using string to create their own spider webs.

In this activity, learners use maps to locate the Northwest Coastal region.

In this activity, learners build a kite out of paper, change it, and try to make it fly even better. With their new knowledge of kite making, students can then go on to create their own kite designs.

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.
