Lets us look over the shoulders of scientists and glimpse the often-unseen moments of investigation. Take virtual field trips to eight observatories -- Arecibo, where astrobiologists search for signs of life beyond the solar system; Las Cuevas, a research station in Central America's largest remaining rainforest; and others. See interviews, photos, and broadcasts that explore the origins of matter, the universe, and life itself.

This OER explores the constellations Orion the Hunter. It contains both an activity as well as resources for further exploration. It is a product of the OU Academy of the Lynx, developed in conjunction with the Galileo's World Exhibition at the University of Oklahoma.

Textbook for ASTRON 102 THE SOLAR SYSTEM at College of the Canyons
Surveys the solar system, including the earth and its motions and seasons; the moon, eclipses, and tides; the content and dynamics of the solar system; planets and their satellites, asteroids, comets, and meteorites; and the evolution of the solar system.

Users can choose a time in geologic history, select the link, and see what the Earth looked liked in the far distant past. Each map features a brief written description of the events occurring at that time, and a link to additional information on the geologic era or period being shown. There are also maps that show what the Earth might look like in the future, 50, 100, and 150 million years from now.

Students learn about parallax in this Moveable Museum unit, in which they use mathematical techniques related to parallax to calculate the height of an object. The eight-page PDF guide includes suggested general background readings for educators, activity notes, step-by-step directions, a Data Sheet and a Tangent Table, and an astrolabe template.

In this Digital Universe activity, students practice the scientific skills of observation, inference, and modeling and learn about scale, perspective, and distance by building a three-dimensional model of something they usually perceive as two-dimensional. The 11-page printable PDF activity includes illustrated step-by-step instructions for the following hands-on and computer-assisted activities:Introducing the Constellations, Making a Two-Dimensional Constellation Model, Introducing Parallax and Luminosity, Using Parallax and Luminosity, and Viewing Orion in Three Dimensions.

The Passport to the Universe space show reveals the universe's wonders in a way never before possible in a planetarium. This comprehensive guide to the space show is designed to help you maximize your viewing. It includes background information to help you prepare for your planetarium field trip, detailed information about what you'll see before and during the show and suggestions for several pre- and post-visit activities to do with your students. There are notes about how the show addresses performance standards and curriculum requirements.

In this activity, students measure volume, mass, and calculate density for pennies of different ages as well as for a copper sample. They will answer questions about their measurements, and use internet resources to write paragraphs about the cause of the pattern they observed in their measurements of mass, and pose and answer a question about what they have discovered.

This module introduces D. Mendeleev's theories and the modern Periodic Table. Electron configuration as a function of table placement is discussed.

Explore our nearest Planetary neighbors with Dr. Catherine Johnson as she demonstrates how she uses remote sensing to delve beneath the surface of the terrestrial Planets. (57 minutes)

Join Charles Kennel, the Director of Scripps Institution of Oceanography in a fascinating review of how scientific understanding of the Aurora Borealis has developed, from the beginning of the scientific rEvolution to the modern space age. (49 minutes)

Students learn about pixels in this Moveable Museum unit, in which they decode a simple digital image from a string of numbers. The eight-page PDF guide includes suggested general background readings for educators, activity notes, step-by-step directions, and activity handouts. There are two versions of the activity, one for Grades K-3 and one for Grades 4-8 Version.

On December 16, 2010, the Zooniverse launched the original Planet Hunters to enlist the public's help to search data from the NASA's Kepler spacecraft for the characteristic drop in light due to an orbiting extrasolar planets (exoplanets) crossing in front of their parent stars. Back then we didn't know what we would find. The project was a gamble on the ability of human pattern recognition to beat machines just occasionally and spot the telltale dip from a transiting planet that was missed by automated routines looking for repeating patterns. It may have been the case that no new planets were discovered and that computers had the job down to a fine art. The gamble paid off. The original Planet Hunters project discovered a bounty of unknown planet candidates and several confirmed planets, resulting from the efforts of nearly 300,000 volunteers worldwide.

In this activity/project, students are able to look through a slide show of information about the planets in our solar system (with the exception of Earth) and select a planet to "visit." Students will then write a postcard home describing the planet they were able to visit.

This fun Web article is part of OLogy, where kids can collect virtual trading cards and create projects with them. Here, they explore the "mind-boggling mysteries" of our solar system. The article opens with a quick review of what we know about our solar system and how we've gathered that information. Students then "explore the mystery" of each planet within our solar system, which is presented though fun facts, evidence, theories, and NASA missions. The article ends with a nine-question quiz that gives students a fun way to test what they've learned.

This activity is a classroom investigation where the students create, in size and distance, a solar system model in proportion to a selected sphere representing the earth.

Walking up and down the hallways of Davey Lab at Penn State, you can find astronomers searching for and characterizing exoplanets, monitoring supernovae and other exploding stars, and measuring the details of the accelerating expansion of the Universe to determine the nature of dark energy. In Astro 801, we learn that with only the ability to measure the light from these distant, unreachable objects, we can still determine how the Solar System, stars, galaxies, and the Universe formed and evolved since the Big Bang. We are all citizens of the Universe, and in fact, you are made of starstuff. Come learn where the atoms in your body came from, and what will happen to them long after we are gone.

This video segment adapted from A Science Odyssey uses animation and archival footage to provide an overview of the theory of plate tectonics.
