What is a "Model"?
Source Institutions
In this activity, learners simulate the behavior of the atmosphere.

Cuica (Laughing Cup): Make a Musical Instrument
Source Institutions
In this activity, you'll use a paper cup, a piece of cloth, and some string to make a musical instrument called a cuica (pronounced KWEE-kah).

Ant Super Strength
Source Institutions
In this activity, learners compare their own strength to ants through a series of physical tests.

Periscope
Source Institutions
In this optics activity, learners build a spy tool to secretly view things over walls or around corners.

Building Fractions Game
Source Institutions
In this math lesson, learners investigate fractions by playing a game.

Evolution in Action: Isolation and Speciation in the Lower Congo River
Source Institutions
In this guided discussion activity, learners watch a video about Central Africa's Lower Congo River, one of the most biologically diverse rivers in the world.

Gumdrop Dome
Source Institutions
In this engineering activity, learners construct sturdy geodesic structures out of gumdrops and toothpicks. Use this activity to explore engineering principles as well as sturdy shapes and triangles.

Throw Your Weight Around
Source Institutions
During this activity, learners take part in a variety of tasks which involve moving and balancing different body parts.

Making a Field Journal
Source Institutions
In this activity, Christina Elson, an archaeologist from the American Museum of Natural History, guides learners as they investigate an "artifact" and record their observations in a field journal.

All Systems are Go!
Source Institutions
In this online activity, learners role-play as medics, treating a patient with missing organs. Learners select different organs, then drag them into the proper location in the patient's body.

Levity Through Tension: Fun with Water's Surface Tension
Source Institutions
This experiment describes how to create a "dribble bottle" which only leaks water when the cap is unscrewed. The full water bottle has a small hole made with a push pin.

Air Pressure and Dent Pullers
Source Institutions
In this activity, learners simulate Otto von Guericke's famous Magdeburg Hemispheres experiment.

Friction Racing
Source Institutions
In this activity, learners explore the unseen force of friction and how surfaces can slow moving objects at different rates.

Sequence Bracelets
Source Institutions
In this craft-based activity, learners make DNA sequence bracelets that carry the code of an organism such as a human, trout, chimpanzee or butterfly.

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

Milli's Super Sorting Challenge
Source Institutions
In this activity, learners separate materials based on their special properties to mimic the way recyclables are sorted at recycling centers.

Defining Dissolving
Source Institutions
In this introductory activity, learners discover that sugar and food coloring dissolve in water but neither dissolves in oil.

Train Your Brain
Source Institutions
In this activity, learners play a trick on their own brain to see if the brain can learn to ignore distracting input. Colors and words are used to play the visual trick, known as a Stroop Test.

Balloon Flinker
Source Institutions
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.

Dance Diagram
Source Institutions
Teams of learners use a series of stick figures made from pipe cleaners to model a dance routine. Then, they use this model to communicate to another learner who performs the dance routine.
