This is a lesson about using the light from the star during an occultation event to identify the atmosphere of a planet. Learners will add and subtract light curves (presented as a series of geometrical shapes) to understand how this could occur.... (View More)

This is a lesson about determining planetary composition. Learners will use a reflectometer to determine which minerals are present (from a set of knowns) in a sample of Mars soil simulant. Requires the use of ALTA II spectrometers (which may be... (View More)

Learners will be introduced to the concepts of error analysis, including standard deviation. They will apply the knowledge of averages (means), standard deviation from the mean, and error analysis to their own classroom distribution of heights. They... (View More)
