In this multi-step experiment (page 4 of pdf), learners study tide pools, and then drop a "wave" (a 4-pound bag of beans or birdseed) on a shell to mimic the force of crashing surf on tide pool animal

In this activity, learners repeat patterns in two and three dimensions to create tessellations. This activity combines the creativity of an art project with the challenge of solving a puzzle.

In this activity, learners build a hovercraft using a paper plate, cup, and simple motor.

In this activity (on pages 9-14), learners dissect a real flower -- the kind of work botanists do.

This activity is designed to introduce learners to genes, genotypes and simple inheritance patterns.

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

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.

In this activity, learners explore the difference between compact fluorescent light (CFL) bulbs and traditional incandescent bulbs.

In this activity, learners will examine various world data maps to combine the information and predict which areas could be tropical rainforests.

In this design challenge activity, learners make a balloon hover at eye level for five seconds, and then make it move by creating air currents.

In this activity, learners investigate the food, water, and space needs of common livestock animals.

This activity (on page 2 of the PDF under SciGirls Activity: Soccer Ball Kick) is a full inquiry investigation into transfer of motion.

In this activity, learners demonstrate and discuss simple circuits as well as the differences between parallel and serial circuit design and functions.
