In this activity, learners will explore coding by arranging words and phrases to create an order of operations in this low tech version of computer programming.

In this activity, learners help a poor cartographer color in the countries on a map, making sure each country is colored a different color than any of its neighbors.

In this engineering activity (page 3 of PDF), young learners investigate how a pole can be made stable by “planting” its base in the ground or adding supports to the base.

In this activity, young learners investigate magnets. Learners discover that some magnets are stronger than others and that magnets have north and south poles.

This is an activity (on page 2 of the PDF under Surface Area Activity) about surface area to volume ratio.

Learners investigate stress and strain by designing, building, and testing beams made from polymer clay.

Learners conduct four simple experiments to demonstrate the effects of air pressure.

In this puzzle, learners investigate the decisions involved in linking a network between houses in a muddy city.

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.

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

Learners listen to and try to decipher a radio message that was sent from Earth to possible intelligent civilizations.

In this activity, learners are challenged to build a bird feeder using recycled materials from home and are encouraged to problem solve during the extensions.

In this activity on page 15 of the PDF, learners measure the amount of bubbles that they make using a detergent.

Space Guess Quest is a fun game that encourages participants to identify the many types of objects in space, from human-made spacecraft to nebulas, galaxies, stars, and worlds.

Using a vertical wind tube and using simple materials, individuals and groups attempt to design a "satellite" that floats for at least 5 seconds.

In this activity (page 1 of the PDF under SciGirls Activity: Water Slides), learners will whip up some suds with a cup of water and a tablespoon of dish soap until the bubbles are stiff enough to star

Learners make a skydiver and parachute contraption and launch it. They see that the drag created by air resistance slows the descent of skydivers as they travel back to Earth.

In this activity, learners build a bird that flies in place with help from a motor, wire, and some straws.

In an investigation called "Shape It!" learners craft tiny boats out of clay, set them afloat on water and then add weight loads to them, in order to explore: how objects stay afloat in water; what th

In this tabletop board game, players will represent a team of scientists and engineers sending a spacecraft on a mission to space.
