In this activity, learners cut out a fish and then "paint" it using universal indicator and acids and bases.

In this activity, learners discover how bats use echolocation to get information about objects in their environment. During the activity, one learner whispers into a tube.

In this demonstration, learners observe the effects of density and pressure. A "diver" constructed out of a piece of straw and Blu-Tack will bob inside a bottle filled with water.

In this activity, learners create a colorful bookmark using a super thin layer of nail polish on water. Learners discover that a thin film creates iridescent, rainbow colors.

In this online activity, learners test their ability to hear different frequencies and compare their frequency range with the frequency range of other animals and insects.

This activity investigates how bark beetles can threaten forests by having learners estimate the number of infected trees from a photo.

In this activity, learners explore the concept of permeability to better understand why amphibians are extremely sensitive to pollution.

In this activity, learners explore the concept of insulation by trying to keep Olaf the Snowman from melting. This activity encourages critical thinking and problem solving.

In this quick activity, learners explore how blubber protects animals from the cold by making a "blubber mitt." Using cooking shortening, two zip-top sandwich bags, and duct tape, learners simulate bl

In this activity (located at the top of the page), learners make an easy river strainer and see what they can catch.

In this activity (on the left side of page 5, continued on the right side of page 4 of the PDF), learners make models of colorful butterflies.

In this group activity, learners will explore the characteristics, functions and uniqueness of the mangrove tree.

In this activity, learners compare frog eggs to chicken eggs to better understand why frog eggs need water. Learners compare a boiled chicken egg to "frog eggs" represented by boiled tapioca.

In this interactive game, learners will test their memory of animal and insect sounds. Flip over cards, listen to the sound, and try to find the ones that match.

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

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

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 investigate how some butterfly wings get their color.

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.
