Jewels of the Night The Jewels of the Night is a hands-on, teacher-tested activity for middle school and older students. Students measure the color and brightness of stars in the Jewelbox Cluster from a color image. They determine the age of the cluster by plotting their measurements in a color-brightness diagram. The activity develops classification and graphing skills and fosters observation, communication, and cooperative learning skills. Students are exposed to ideas about the nature of stars, temperature and color, stellar evolution, the time scales of astronomical phenomena, and how astronomers can determine the ages of objects in the universe.
Hubble Galaxy Formation In this exercise, you will learn to classify galaxies using the Hubble Classification scheme. You will also find their distances using the Hubble law.
Hubble's Law The student will determine a value for Hubble's constant, based on their observations of the images and spectra of 12 spiral galaxies.
I've Got Your Number In this lesson, students assess the journalistic value of numbers used in newspaper articles while learning about the significance of the Hubble telescope's new data on the age of the universe.
The Formation of the Solar System Any model of the formation of the solar system must account for the motions, compositions and locations of all the planets and their moons. In this lab, you will use the motions of objects in the solar system to concoct a model of the formation of the solar system.
A Keck Spectrum Using Hubble's Law, determine the distance to this object. Ultimately, estimate the power of the gamma ray burst from its measured flux at Earth and its distance from us.
Exploring Planets: More than 25 hands-on science activities are provided in classroom-ready pages for both teachers and students for exploring Earth, the planets, geology, and space sciences.
