This is a collection of outreach resources about the Sun that are meant to be used in informal education settings. This toolkit was originally designed for NASA Night Sky Network member clubs and the Astronomical Society of the Pacific's Astronomy... (View More)
This textbook chapter traces the historical development of the modern scientific understanding of light, and reviews the electromagnetic spectrum and the Earth's atmospheric shield. The resource includes links to current news articles, and a suite... (View More)
This model demonstrates convection currents and uses water, food coloring, a cup of very hot water and a votive candle as heat sources. Movie clips of demonstration setup and convection in action are provided. This activity is supported by a... (View More)
In this lesson on cosmic rays, students will explain two examples of a cosmic ray detector. Includes information about student preconceptions and a demonstration that requires a geiger counter and optional access to a small radioactive source that... (View More)
This is an activity about magnetism. In this activity, polystyrene spheres and several strong neodymium magnets are used to represent the Sun and Earth and their distinct magnetic fields. Participants construct and use a field detector to predict... (View More)
In this activity, students use mathematics to understand tides and gravitation and how gravity works across astronomical distances, using an apparatus made from a slinky, meter stick, and a hook. A description of the mathematical relationships seen... (View More)
These short leader guides are designed for a novice user to pick up and implement the activities with ease. They address a range of topics all related to asteroids - most especially Asteroid Vesta. Activities are tagged to quickly find ones that are... (View More)
In this activity, students are reminded that the Universe is made up of elements and that the heavier elements are created inside of a star. They are then introduced to the life cycle of a star and how a star's mass affects its process of fusion and... (View More)
This is a lesson about detecting atmospheres of planets. Learners will explore stellar occultation events (by interpreting light curves) to determine if an imaginary dwarf planet "Snorkzat" has an atmosphere. The activity is part of Project Spectra,... (View More)
Learners will explore different ways of displaying visual spectra, including colored "barcode" spectra, like those produced by a diffraction grating, and line plots displaying intensity versus color, or wavelength. Students learn that a diffraction... (View More)
