In this online interactive, learners will explore how scientists learn about the composition of an asteroid by studying energy and neutrons that emanate from it. Includes audio (and transcription) explaining the diagram.
This interactive, online activity provides a method for generating waves using a computer. Students can select the energy they want the waves to have, observe how the waves appear on the screen, and then measure the frequency and wavelength of the... (View More) observed waves. Upon completion of this activity, students will have uncovered the relationship among frequency, wavelength, and energy. Students may complete this activity independently or in small groups. Detailed teacher pages, identified as Teaching Tips on the title page of the activity, provide science background information, lesson plan ideas, related resources, and alignment with national education standards. This activity is part of the online exploration "Star Light, Star Bright" that focuses on the electromagnetic spectrum and that is available on the Amazing Space website. (View Less)
In this assessment activity, students generate a data sample from either the Hubble Deep Field-North or Hubble Deep Field-South images, and compare the sample to data from the unselected field. This provides students with a real-life example of how... (View More) statistics can be used by scientists. After completing this activity students will be able to compare sample data with the population parameter to determine accuracy of sampling techniques and use statistical data to make conjectures about the universe. This interactive online activity is part of the online exploration “Galaxy Hunter”. Detailed teacher pages, identified as Teaching Tips on the title pages of the activity, provide science background information, lesson plan ideas, related resources, and alignment with national education standards.
