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

In this activity, learners sniff out scents hidden in balloons! After investigating, learners discover we sometimes can use another sense (smell) to detect things too small to see.

In this activity, learners use a flexible magnet as a model for a scanning probe microscope (SPM). They learn that SPMs are an example of a special tool that scientists use to work on the nanoscale.

In this activity, learners use their imaginations and experiment with different materials to create bug hats.

In this activity, learners investigate circulation and measure their own your heartbeat. A heart rate, or pulse, is the number of times the heart beats per minute.

This open-ended art project allows learners to create their own colorful ice sculpture by using rock salt and food coloring on a solid block of ice.

In this math lesson, learners explore the concept of using units to measure length. Learners first read "How Big is a Foot" by Rolf Myller and learn about units.

In this activity, learners listen to a story and tell a story of their own as they learn about the importance of elders in Native American cultures.

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

In this activity, the learner will experiment with the physics of sound production while making a sound making toy. The activity includes a video with step by step instructions.

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

In this activity, learners will explore reptile biology by taking temperature readings in various places and comparing them.

In this activity (on pages 41-47 of PDF), learners explore tesselating geometric patterns (repeated shapes, similar to the art of M.C. Escher).

In this activity, multiple learners will use a game with ballloons to learn about coqui frog behavior.

In this is activity about sound and vibration, learners create their own 'flutes' with drinking straws, then investigate how changing the length of the straw affects the sounds that are produced.

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

In this collecting/comparing activity, learners work with samples of sand from different places like a lakefront, river, or ocean beach.
