The Goldilocks Zone

Performance Expectations

MS-ESS1-1  Develop and use a model of the Earth-sun-moon system to describe the cyclic patterns of lunar phases, eclipses of the sun and moon, and seasons.


MS-ESS1-2  Develop and use a model to describe the role of gravity in the motions within galaxies and the solar system.


MS-ESS1-3 ​Analyze and interpret data to determine scale properties of objects in the solar system. This is a final project after also covering


MS-PS2-4  Construct and present arguments using evidence to support the claim that gravitational interactions are attractive and depend on the masses of interacting objects.


The students spent time learning about the planets, special features of these planets and scale proportion of the planet diameter and the distance from the sun.  After several scale drawing and models, the students were given the challenge of creating a scale model the size of their science lab tables and provide evidence why life exists on Earth.

Why is earth habitable for life? Is it the Goldilocks Zone?
