 Gravity 2015-­‐16 Next Generation Science Standards: 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. [Clarification Statement:
Examples of models can be physical, graphical, or conceptual.]
MS-ESS1-2.
Develop and use a model to describe the role of gravity in the motions within galaxies and
the solar system.[Clarification Statement: Emphasis for the model is on gravity as the force that
holds together the solar system and Milky Way galaxy and controls orbital motions within them.
Examples of models can be physical (such as the analogy of distance along a football field or
computer visualizations of elliptical orbits) or conceptual (such as mathematical proportions
relative to the size of familiar objects such as students' school or state).] [Assessment Boundary:
Assessment does not include Kepler’s Laws of orbital motion or the apparent retrograde motion
of the planets as viewed from Earth.]

y/facts.cfm Gravity Notes gravity-­‐a force that pulls force-­‐a push or a pull mass-­‐
the amount of matter (or “stuff”) in an object weight-­‐
the strength of the gravity (or gravitational pull) on an object ALL objects have a gravitational pull. Some pulls are strong, others are not. What determines the strength? Answer: 2 factors determine the strength of gravity: 1) mass of the object(s) 2) distance between the objects (close to each other means STRONG gravity, far away from each other means WEAK gravity). Directions: Write a paragraph explaining how you know: .
.
A) Gravity is a force that pulls B) Gravity’s strength depends on mass and distance 3 Examples 1.
The earth has a lot of mass and pulls almost all things towards its center. 2.
The moon has a lot of mass. Every time it passes over a coast or shore its gravity pulls the water up. When the moon leaves the water moves back down. 3.
The planets in our solar system orbit the sun. The planets would like to fly away from the sun into outer space but the sun has so much mass and such strong gravity it “holds onto” them and forces them to orbit.
