In this activity, learners will explore surface tension, what it is, and how we can change it.

In this outdoor activity, learners turn the fun of feeding wild birds into an investigation of bird behavior.

In this outdoor, nighttime activity, learners gather around a brightly lit, white surface and study the behavior of nocturnal animals attracted to the light, particularly night fliers.

In this physics activity, learners experiment with the attractive and repulsive power of magnets.

In this activity, learners cut, fold, and paste paper representing biomolecules to create a three-dimensional cell membrane with embedded proteins.

Learners develop an understanding of air pressure in two different activities.

In this activity, learners will experiment to find how long it takes to compost paper. They will create their own compost container and test different variables.

In this story time program, young learners listen to the Dr.

In this activity, learners will design a seed and test how it travels. Learners will use the Engineering Design Process to create a seed which can move from place to place.

In this food science activity, learners observe different plant-originated foods.

In this activity about electricity, learners identify closed and open circuits. First, learners examine and label diagrams of open and closed circuits.

In this activity about bones (page 12 of PDF), learners investigate and compare the weight-bearing capacity of solid and hollow cylinders.

In this environmental health activity, learners grow and observe bread mold and other kinds of common fungi over the course of 3-7 days.

In this activity, learners will build a stomp-powered launcher to blast off paper rockets they design. Materials can be found at a local hardware store or you may already have them at home.

In this nutrition activity (page 16 of PDF), learners document their individual eating habits and learn whether their eating patterns meet their needs.

In this ecology activity (page 8 of the PDF), learners explore how to filter contaminated water using a variety of materials.

In this math lesson, learners apply measurement skills to determine, in dollar bills, the capacity of a suitcase.

Learners follow directions to construct a water-powered electrical generator using a turbine made from plastic spoons.

In this activity about states of matter, learners get to witness firsthand the awesome power of air pressure. They watch as an ordinary soda can is crushed by invisible forces.

In this activity related to microbes, learners use water drops and hand lenses to begin the exploration of magnification. This activity also introduces learners to the microscope.
