In this activity, learners build a sled kite that models a type of airfoil called a parawing.

In this interdisciplinary activity, learners create a Space Weather Action Center (SWAC) to monitor solar storms and develop real SWAC news reports.

In this space science activity, learners explore transits and the conditions when a transit may be seen.

In this activity, learners investigate parallax, a method used to measure distances to stars and planets in the solar system.

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 activity, learners construct hand-held altitude trackers. The device is a sighting tube with a marked water level that permits measurement of the inclination of the tube.

In this activity, learners sample a star field to estimate the number of stars in the universe.

In this robotics activity, learners drive a remote-controlled car through a course to learn the challenges faced while trying to operate a planetary rover.

In this activity, learners build small indoor paper rockets, determine their flight stability, and launch them by blowing air through a drinking straw.

This interactive demonstration reintroduces learners to three states of matter (solid, liquid, gas), and introduces them to a fourth state of matter, plasma.

In this activity, learners simulate a multistage rocket launch using party balloons, fishing line, straws, and a plastic cup.

In this activity, learners explore the magnetic field of a bar magnet as an introduction to understanding Earth's magnetic field. First, learners explore and play with magnets and compasses.

In this sunny day, outdoor activity, learners observe changes in shadows over time. The activity also helps to develop a sense of the Earth's motion.

In this activity, learners explore how distance can affect the way we perceive the size of an object.

In this geography investigation, learners use a nighttime satellite image to observe areas of light across the United States and to identify patterns and spatial distributions of human settlements.
