Eight interactive tutorials are available. In one tutorial, students match the names and characteristics to the layers of the atmosphere. Students may jump to different locations in the program or look up scientific terms in the glossary. They can turn off the audio portion of the program or exit the program at any time. A forty question pretest and post test have the options of showing the response feedback, showing the results during the test, and determining the time allowed for each response.
Students can both see and hear the multiple choice questions.
