Eclipses Interactivity
Can you devise a model of an eclipse for a movie studio?
Record Data and Observations
1. In the interactivity, drag the moon to various positions relative to Earth and the sun. For each
model, click the Check Model button to find out what the sun looks like from Earth and
whether or not the arrangement is consistent with observations of eclipses. Explore at least
four arrangements in addition to the correct arrangement.

Earth, moon,
and sun

in this model
Results: How is this
model consistent with
observations? How is
it not consistent?
