In this neuroscience activity, learners conduct a simulation to demonstrate how multiple incoming signals influence the action of neurons.

This is a simple activity fully driven by imagination. Using materials from the home, toys, or items from nature, learners create their own world to play with.

In this activity, learners conduct a simulation exercise related to public key encryption and try to intercept a message sent between two learners.

In this design challenge, learners will practice empathy and design thinking skills by creating a play space that is fun, both for themselves and other kids.

This activity introduces the idea that computer scientists measure information by how "surprising" a message is.

In this fun math activity (page 5 of the pdf), learners will help a secret agent crack a case by solving math problems.

This activity (page 1 of the PDF under SciGirls Activity: Exercise and Memory) is a full inquiry investigation into the effects of exercise on short term memory.

In this outdoor activity (on page 2 of the PDF under GPS: Baseball Activity), learners will investigate the transfer of energy using sports equipment.

In this activity, learners work in small groups to match various marine animals with their different environments.

In this activity (on page 1 of the PDF under SciGirls Activity: Soccer Ball Kick), learners will investigate the transfer of energy using sports equipment.

In this activity, learners make a scale model of an atom to see how big or how small an atom is compared to its nucleus. Learners will realize that most of matter is just empty space!

In this activity, learners will review the functions of basic digestive organs, understand how diet affects digestion, understand how digestive tracks may differ, and then step outside to compare the

In this game of chance, learners will discover how organisms colonized the Galápagos Islands, experiencing how chance plays a role in the successful dispersal of species to new areas.

On an airplane trip, learners have an opportunity to investigate the properties of air pressure at different altitudes.

In this environmental activity (page 6 of the PDF), learners identify household products that are recyclable and explore the different types of recyclable plastics.

This activity introduces the idea of "divide and conquer" using a fictitious but serious problem--a pair of dirty socks has accidentally been wrapped in one of the presents that Santa is about to deli

This activity is a sensory experience that recreates the sounds of a pond at night.

In this activity, learners map their world by drawing a plan of their bedroom.

Using simple materials from around the house and recycled materials, learners will engineer a grabber device to pick up and put down objects that are at least 12 inches away.
