En esta actividad, los participantes explorarán las fuerzas de gravedad y la resistencia al aire usando paracaídas.

In this activity, learners build a model roller coaster to help the Mummy entertain the Atom's Family monsters. Learners assemble the roller coaster between two chairs using vinyl ceiling molding.

In this design challenge activity, learners build a device to carry a Ping-Pong ball from the top of a zip line to the bottom in four seconds (or less!).

In this activity, learners make pretend snakes and use them to explore estimation and measurement. Learners roll out clay snakes and estimate and measure their lengths and diameters.

In this activity, challenge learners to design a roller coaster ride for a marble using cardboard and other simple materials.

This lesson plan provides learners with two activities to explore the connections between events in their lives and the seasons of the year.

In this math activity, learners trace their hands and estimate the number of beans that can fit into their hand tracings. Then, learners glue the beans to the tracing to test out their estimations.

In this chemistry activity (page 3 of the PDF), learners will learn about crystals by growing their very own.

In this demonstration about force and motion, learners will explore the forces that affect a pendulum A simple model pendulum comprised of a ball and string demonstrates how pendulums work as well as

Learners make their own acid-base indicator from red cabbage. They use this indicator to test substances around the house.

In this activity, learners build a seesaw powered by magnets.

In this activity, learners explore sound by constructing their very own banjo out of a coffee can. Learners experiment with the canjo to change the instrument's pitch and timbre.

In this activity, learners build mini catapults using paint paddles and a spoon. Use this activity to introduce learners to forces and projectile motion.

This lesson guide includes six simple and quick activities to help learners better understand Bernoulli's Principle.

In this activity, learners separate materials based on their special properties to mimic the way recyclables are sorted at recycling centers.

In this activity, learners make a helium balloon "flink"--neither float away nor sink to the ground. Use this activity to introduce physics concepts related to gravity, density, and weight.

In this archaeology-related activity, learners build their own time capsule and choose a storage location and a date to reopen it.

In this activity, learners will use a compact disc to build an air puck that can glide across a smooth tabletop. The puck glides with almost no friction on a cushion of air escaping from a balloon.

In this lab (Activity #1 on page), learners explore how we see color.

In this activity, learners explore the flexibility of polymer chains by pushing sharpened pencils through a Ziploc bag.
