In this activity, learners build a scale model of the solar system using a roll of toilet paper.

In this physical activity, two lines of learners link hands and arms to model a beam subject to various loading schemes.

In this activity, children and adults work together to explore their relationship with technology and examine ways to make sustainable media consumption choices.

In this activity, learners play an evolution card game to see how selective pressures can affect an organism's evolution.

In this activity, learners make water rockets to explore Newton's Third Law of Motion. Learners make the rockets out of plastic bottles and use a bicycle pump to pump them with air.

Learners create their own piece of history by decorating, shattering, and piecing together a flowerpot "artifact".

In this activity related to computer programming, learners give directions to a "robot" (either an adult or another learner) and find out which instructions the robot is able to follow, and how their

In this activity (on page 4), learners create a submarine using a plastic sandwich bag. This is a fun way to learn about buoyancy and how captured gas can cause objects to float.

In this activity, learners explore how pneumatics and hydraulics could be used to produce movement in a robotic arm.

¡Este juego de estrategia tiene reglas sencillas pero puede ser un reto! Los jugadores empiezan con una red de hexágonos vacía. En su turno cada jugador pone su inicial en un hexágono vacío.

With a coffee filter, a black marker, and a cup of water, discover the secret colors hidden in black ink.

In this activity, learners create a tornado in a bottle to observe a spiraling, funnel-shaped vortex. A simple connector device allows water to drain from a 2-liter bottle into a second bottle.

In this activity, learners will plan a snack within a budget. With a $20 limit (theoretical) to spend on snack for everyone, learners look over grocery store circulars and make their shopping lists.

This activity shows you how to make a mold terrarium using a jar and leftover food.

In this board game, learners explore the origins of meteors, meteoroids, and meteorites as well as the their characteristics and importance. They also discover some misconceptions about meteors.

In this activity, learners will be able to measure themselves in nanometers. A nanometer is a billionth of a meter, a unit of measurement used in nanotechnology.

In this chemistry activity, learners observe a combustion reaction and deduce the components necessary for the reaction to occur.

In this math lesson, learners play a game to identify the properties of prime, composite, abundant, deficient and perfect numbers.

This is a demonstration you can use to show learners how valves and pumps work in concert to move blood through the circulatory system.

In this activity (on page 2 of the PDF under GPS: Cactus Activity), learners will develop their own version of a tool used by biologists, a dichotomous key, by collecting all their left shoes.
