Learners investigate the concept of humidity by using a dry and wet sponge as a model. They determine a model for 100% humidity, a sponge saturated with water.

This is an activity that models the operation of a seismograph, a tool used to measure the size of earthquakes.

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

This activity explores the main algorithms that are used as the basis for searching on computers, using different variations on the game of battleships.

Some aquatic organisms live in open water, while some live in soil at the bottom of a body of water.

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.

In this math activity (Page 12 of the Play Ball! PDF), learners play a game of "soccer" and analyze the results of the game.

In this activity, learners construct a simple game to test their hand-eye coordination and steadiness of hand.

In this introductory demonstration and activity, learners are introduced to the concept of density as they explore a rock and a wooden block in water.

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

In this chemistry activity (page 1 of PDF SciGirls Activity: Milk Carton Boat), learners will create a blob of stretchable funny putty out of a water, borax, and glue mixture.

In this design challenge activity, learners use a balloon and other simple materials to design an air-powered rocket that can hit a distant target.

In this activity, learners build an electric two-paddle boat using paint paddles, plastic knives, and empty water bottles.

In this math activity (Page 14 of the Play Ball! PDF), learners play a game of "basketball" and analyze the results of the game.

To learn how friction affects motion, learners build a measurement tool from a rubber band and other simple materials.

In this simulation, learners use M&M™ candy to explore radioactive isotope decay.

In this activity, dry ice and other items are used to construct a demonstration model of a comet that illustrates the comet nucleus, coma, and tails.

Learners build a simple hovercraft using air from a balloon to levitate a craft made from a compact disc (CD).

In this engineering activity, learners investigate the differences between the strength of bridges made from flat and round building materials.

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