of "Online exploration: Hubble Deep Field Academy"
Online exploration: Hubble Deep Field Academy examines the galaxies in the Hubble Deep Field North, the first of two deep visible-light images of the universe (the other is the Hubble Deep Field South). Students will simulate the process astronomers went through to count, classify, and identify objects in the image as well as estimate their distances from Earth.
Format(s) available: Online interactive
Grades: 6-8, but the material can be adapted for use in other grades at the teacher's discretion
Educator Guide: See online teacher pages.
How to use it in the classroom
Online exploration: Hubble Deep Field Academy can be used to introduce students to the Hubble Deep Field and the science involved in determining the number, color, type of galaxies in the Hubble Deep Field and their distances from Earth. The orientation module introduces the Deep Field and invites students to look at the image and write five questions about the objects in the image. The first module can be used to introduce one method of statistical sampling used to estimate the number of galaxies in the Deep Field. The second module can be used to introduce characteristics and colors of stars and galaxies. Each module has a worksheet (Hubble Academy Log, or "HAL") associated with it and can be used to track students’ thinking.
Extension activities include student math worksheets: "What Does a Million Look Like?," "999,999 Cans of Soda on the Wall," and "How Many's a Million? Billion? Trillion?"

See the Galaxies section on "Teaching tools" page.Grab Bag section, which can be found by clicking on "Deep Field Links" on the first page of the activity. The Hubble Academy Log (HAL) worksheets accompany the activity and can be printed for use while the students are working through the activity. In addition, there are several pages that are presented as PDF files that can be downloaded for use in classrooms without computers. Extension activity worksheets can also be printed from the Grab Bag.
