Learners investigate the properties of the liquids in two bottles. One contains layers of oil and water, and one contains oil, water, and soap.

In this interactive board game, learners "hire" different types of scientists to help canine character Ruff Ruffman solve unusual problems.

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

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

This is an online simulation of how sound changes due to environment. How does place--like a cave, a pier, or a forest--affect certain sounds?

In this activity, learners build a cuica or chirping bird using straw, string, and a bottle cap. Use this activity to explore the interplay of motion and sound.

In the wild, small crustaceans known as brine shrimp live in marine habitats such as saltwater lakes.

In this activity (page 1 of the PDF under SciGirls Activity: Horse Ears), learners observe how an animal responds to its own reflection.

In this lab, learners experience how dolphins and other echolocating animals use their senses to locate and identify objects without using their sense of sight.

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

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

In this activity, learners explore the factors that tend to resist changes in pH of the ocean and why the ocean is becoming more acidic.

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

In this game, learners try to find nano-related objects on a game board. Learners investigate the different ways nano is in the world around us.

In this field study, learners discover how to collect data in the field and how their efforts can help certain animals, specifically, amphibians.

This activity (on page 3 of the PDF under GPS: Cactus Activity) is a full inquiry investigation into how some desert birds keep their cool.

In this math activity, learners use a "function machine" to collect and organize simple data. The function machine in this case is a cardboard box and the input/output data are paper fish.

In this activity, learners will discover how the thin layers of amphibians' skin allow water and other chemicals to pass through it.

The Butterflies in Space Teacher's Guide uses "life in space" to encourage learners to conduct their own open-ended scientific investigations.

In this family or group activity, learners create a nature journal by visiting a local nature center or backyard, observing creatures in their natural habitats, and sketching what they see.
