In this outdoor activity and observation game, learners hunt for a variety of textures, colors, odors and evidence of organisms in the activity site.

In this activity, learners set up a night time insect observation station with a light and sheet.

In this project, students explore how levers work, by making a puppet with moving limbs.

In this activity, you'll make an electric motor--a simple version of the electric motors found in toys, tools, and appliances everywhere.

In this math activity (Page 8 of the Dining Out! PDF), younger learners select items from a menu and count out the total amount needed using the fewest bills and coins possible.

In this game, learners use clues to identify mystery shapes. Use everyday objects (like from the pantry) as the shapes.

Heat makes some materials expand, and it makes others shrink.

In this activity, learners will discover why there are holes in bread.

In this math game (Page 15 of the Dining Out! PDF), learners figure discounts and/or profit increases for various food totals. Learners add decimals to $100.

In this activity, learners explore chemiluminescence and fluorescence. Learners examine 3 different solutions in regular light, in the dark with added bleach solution, and under a black light.

In this activity, learners make a photographic image—without a camera!

In this activity, learners are challenged to design a planktonic organism that will neither float like a cork nor sink like a stone.

In this activity, learners analyze a fictionalized report of life on Mars, based on a real NASA satellite photo, and explore how to separate scientific fact from fiction.

In an investigation called "Shape It!" learners craft tiny boats out of clay, set them afloat on water and then add weight loads to them, in order to explore: how objects stay afloat in water; what th

In this investigation, learners explore the force known as buoyancy by placing various objects into water and observing how they behave (for example, which sink more quickly, which float, how much wat

In this hands-on activity, learners use the steps of the design process to create a hook to rescue a "space capsule" from the water.

What's a more compelling problem to solve than being stranded on a deserted island?

In this chemistry activity, learners witness an exothermic reaction, while making their very own, completely usable sidewalk chalk. This is also an excellent activity for exploring color mixing.

Learners explore the Bernoulli effect by building an airfoil (airplane wing) and making it fly.

Learners design their own experiment to investigate how pollution diffuses through ground material.
