Students begin this activity by building a model of Earth’s magnetic field using a bar magnet to show Earth’s Ring current (the magnetic field which is in opposition to Earth’s magnetic field). Using this model, students will then observe the... (View More)

Become a crime scene investigator! Learners model Dawn Mission scientists, engineers, and technologists and how they use instrumentation to detect distant worlds. After a briefing to build context, students explore interactions between different... (View More)

This paper model shows the orbit of Comet ISON (late 2013) with respect to the innermost planets of the solar system. After reading background information about comets - how they form and where they come from - students cut out and tape together the... (View More)

This is a make-it-yourself planisphere designed to show where Kepler is pointing. Learners can use it to locate exoplanets around stars in the night sky. It comes with two wheels: one with coordinate grid for plotting additional exoplanet stars and... (View More)

In this demonstration activity, students make structural models of gas molecules using pipe cleaners and polystyrene balls and test their molecules for their resonant frequency. Students shake the models, count vibrations, and compare the resonance... (View More)

The H-R diagram is a scatter graph of stars, a plot of stellar absolute magnitude or luminosity versus temperature or stellar classification. It is an important astronomical tool for understanding how stars evolve over time. Stellar evolution cannot... (View More)

In this lesson, students measure the size of several galaxies to reproduce a plot of Hubble's Law. The goal of this lesson is to give students the chance to simulate the process that led to the notion that the universe is expanding, provide insight... (View More)

This is an activity about observing and mapping sunspots by direct solar observation. Learners will use a small telescope, binoculars, or a Sunspotter to create a projected image of the Sun and trace the position of any observed sunspots on a piece... (View More)

This is an activity about solar rotation and sunspot motion. Learners will use a sphere or ball to model the Sun and compare the observed lateral motion of sunspots to their line-of-sight motion. This is Activity 1 of the Space Weather Forecast... (View More)

This lesson examines the effects of surface energy transfer and storage on ocean temperatures. Included are activities that introduce the use of scientific models. Students then use an energy flow computer model to track energy changes by... (View More)
