Learners will use the inquiry process to explore the affect of atmosphere on the temperature of a planet. They create a model of the system to test. They then create a concept map of the planetary temperature system. The lesson models scientific... (View More)

Audience: Middle school

Learners will predict how human survival requirements are met by characteristics of our solar system and planet. They engage in an online Astronomy Training module in which they make changes to the astronomical conditions of our solar system and... (View More)

Audience: Middle school

This interactive, online activity introduces the idea that everything emits electromagnetic radiation, including students. Students discover how the light emitted from an object (a robot) changes as the object is heated. A graph shows the amount of... (View More)

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)

Audience: High school

In this interactive, online activity, students view an image of an "oddball" object from the Hubble Deep Field image that has been difficult for astronomers to classify. Students make their own interpretations of the object based upon knowledge... (View More)
