This is a virtual representation of a sound mixer containing pre-looped sounds of animal, insect, and environmental noises.

In this activity, learners of all ages will design a functional bird feeder using familiar, every day materials.

In this activity, learners make water-walking critters using thin wire, and then test how many paper clips these critters can carry without sinking.

In this activity with several mini experiments, learners explore the chemistry that helps scientists learn about the environment and how they can help save it.

In this design challenge activity, learners explore the concept of biomimicry by using a natural organism's special features to design a new human object.

In this activity (page 89 of the PDF), learners compare and contrast pitch and roll motions by using a Magic Carpet maze similar to one that was used for Neurolab investigations about microgravity.

This activity (located on page 4 of the PDF under GPS: Sea Turtles Activity) is a full inquiry investigation into testing a repair material.

In this activity, learners use found natural materials to create a water haven for bees and other insects.

In this activity about problem-solving, learners build a house for the Three Little Pigs using twenty straws and two index cards.

In this activity, learners assemble large cubes to make nano-related images. Learners discover how different objects are related to nanoscience and nanotechnology.

In this activity, learners examine nanoscale structures of common things.

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 will discover how fossils are dug out of the earth by carefully exposing treasures hidden in an artificial rock that is easily made at home.

In this activity, learners investigate the history and development of agricultural biotechnology.

In this engineering design challenge, learners make a bird and then control its flight with attached strings.

In this activity, learners investigate how some butterfly wings get their color.

In this outdoor activity, learners plan a simple foot path and create an environmental impact study of the natural area where the path would be.

In this activity, learners construct a traditional handicraft toy that illustrates a motion commonly associated with violins and earthquakes.

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

In this activity/demo, learners examine a synthetic gecko tape with micron sized hairs that mimics the behavior of the gecko foot.
