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

Learners use simple materials to construct a model the Big Dipper. Learners hang the model from a doorway or ceiling and look up at it to see the constellation as seen from Earth.

In this activity, learners use a pencil, magnets, and mat board to illustrate Newton's Second Law.

In this activity, learners create their own weather forecast map.

In this activity, learners use colored candy to represent subatomic particles and make a model of an atom (Bohr model).

Put the math of measurement, numbers, and everyday life into improvisational skits.

In this design activity, learners create a vehicle that can transport a load, like a favorite toy or as a recycled object, from the top of a zipline to the bottom using only gravity.

In this activity, learners make their own encrypted code to pass along secret messages using a printable cipher wheel.

In this activity (page 4), learners work in groups to plan and build large structures using recyclable materials they have brought from home.

In this activity, learners discover how their heart rate changes in different situations.

Learners drop a magnet through a coil of wire to create electric current in a circuit. LEDs in the circuit allow learners to detect the direction of current flow.

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 creative roleplay activity, learners will explore the various processes of the carbon cycle using movement and props to aid in comprehension.

In this activity, early learners create paintings by making music and rhythm. Learners place paper in cans, add paint-soaked beans (or pebbles) and put the tops on.

Working in small groups, learners receive a written scenario regarding a bacterium with a certain goal it must carry out.

In this activity (page 2 of PDF under GPS: Cave Swallows Activity), learners will model how caves are formed by placing one piece of chalk in a cup of vinegar and another piece in a cup of water, then

In this engineering activity, young learners investigate multi-level buildings.

Choose a recipe to double (or triple, quadruple, or halve). Show everyone the recipe and engage them in figuring out: How much will we need to increase the recipe to feed everyone?

This activity includes several games about animal sounds. Using their sense of hearing and communicating with various kinds of noisemakers, learners role-play predator and prey.

In this activity, learners are challenged to eat some candy as a cell would need to as well as to think about some of the problems that arise when a cell ingests food.
