Online Exploration: No Escape: The Truth About Black Holes provides an opportunity for students to research the fascinating topic of black holes and to examine the concepts of escape velocity, gravity, mass, and the speed of light as they apply to black holes. Dramatic illustrations and spectacular Hubble Space Telescope images illustrate the activity and provide data that the students will use to hunt for black holes in the centers of galaxies.
Online Exploration: No Escape: The Truth About Black Holes can be used to reinforce the concepts of escape velocity, gravity, mass, and the speed of light as they apply to black holes. Teachers can also use the activity as a writing assignment since the assessment portion asks students to write an explanation of black holes to a chosen audience. Students can choose one of six audiences: an elementary, middle school, high school or college student; an astronomer; or a newspaper reporter.
