In this activity, learners add different liquids to water and apply their working definition of “dissolving” to their observations.

This hands-on astronomy activity lets learners hunt for different objects in the night sky that contribute to stellar and planetary formation, using a Treasure List.

Closing one eye eliminates one of the clues that your brain uses to judge depth. Trying to perform a simple task with one eye closed demonstrates how much you rely on your depth perception.

In this activity, learners compare the ancient Egyptian system of measurement, which was based on body lengths, to the customary and metric systems used today.

In this activity, learners will be making the opposite of a bubble, an anti bubble! This low start up activity is fun, informative, and best of all-a little messy!

In this activity, learners explore the web of connections among living and non-living things.

Learn about chemical reactions by making a Bubble Bomb, a plastic bag you can pop with the power of fizz.

The "Exploring the Solar System: Magnetic Fields" activity shows participants how scientists can use tools to study the invisible magnetic fields of Earth, the Sun, and other objects in the universe.

In this activity, learners use detergent solution to compare two solutions containing vinegar and cream of tartar.

In this activity, learners play a game similar to Hangman by guessing a secret phrase to understand how computer scientists measure the amount of "information" in a document.

In this activity, learners will collect, dry and press seaweed over the course of four days in a similar way that artists/crafters press flowers.

In this activity, learners act out the flow of blood in the human body! A great way to get learners up and moving while learning about the circulatory system.

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.

In this activity (on page 2 of the PDF), learners explore surface tension by adding pennies to cups which are "full" of plain water or soapy water.

In this activity, learners can play two card games related to endangered species, specifically North American amphibians.

In this activity, learners will use their five senses to explore a nature-based area around them.

This simple activity uses paper and scissors to convey two key concepts to learners: the nanoscale is very small and working on the nanoscale requires special tools.

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 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 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.
