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

In this activity (located on pages 23-24 of the PDF), learners are introduced to structural engineering and encouraged to practice goal-oriented building.

Learners will build a lung model to understand how their lungs and diaphragm work to make them breathe.

In this activity, learners make a scale model of an atom to see how big or how small an atom is compared to its nucleus. Learners will realize that most of matter is just empty space!

This fun and simple hands-on astronomy activity lets learners explore model planets (that they or an educator will create), using methods NASA scientists use to explore our Solar System.

In this activity, learners build a hot air balloon using just a few sheets of tissue paper and a hair dryer.

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 investigate a pre-constructed mystery tube to determine its interior mechanism.

In this activity, learners are challenged to design a planktonic organism that will neither float like a cork nor sink like a stone.

Directed by instructional cards, learners kinesthetically model cell communication by acting as components in a cell signaling pathway.

This activity provides a hands-on experience with a scale model, a relatively high viscosity fluid, and feeding behaviors.

In this activity, learners create air cannons out of everyday materials. Learners use their air cannons to investigate air as a force and air pressure.

In this activity, learners gain knowledge about how carbon moves through all four of the Earth’s major spheres (biosphere, hydrosphere, atmosphere, and lithosphere), and understand how humans influenc

In this activity, learners create virus models, including nucleic acid and proteins, using simple materials. This resource includes information about virus structure and gene therapy.

By tossing, collecting, and sorting beanbags, learners understand how the IBEX spacecraft uses its sensors to detect and map the locations of particle types in the interstellar boundary.

In this activity, learners use three types of cheesy snacks--cheese balls, cheese puffs, and Cheetos--to learn about polymers.

In this activity, learners explore how the shapes, sizes, and distances of land masses appear differently on two different models of Earth: an icosahedron and a flat map.

In this yummy earth science activity (page 5 of the PDF), learners use fudge to learn about different kinds of lava.

A group of learners has an envelope containing a series of bank checks. A few checks are removed at a time, and the team attempts to construct a plausible scenario which involves those checks.

In this activity, learners cut out and fold their own collapsible origami starshade, an invention that shields a telescope's camera lens from the light of a distant star so that NASA scientists can ex
