Category 1: Gravity & Motion (SC.8.E.5.4)
This force pulls objects toward each other.
👉 What is gravity?
This model places Earth at the center.
👉 What is the geocentric model?
A scientific theory is a well-supported ______.
👉 What is explanation?
Planets closer to the Sun are generally…
👉 What is hotter?
The Moon orbits Earth because of this force.
👉 What is gravity?
The greater the mass, the ______ the gravitational force.
👉 What is stronger?
This model places the Sun at the center.
👉 What is the heliocentric model?
True or False: A theory is just a guess.
👉 What is false?
This planet has the strongest gravity due to its size.
👉 What is Jupiter?
A small rocky object orbiting the Sun.
👉 What is an asteroid?
This keeps planets moving around the Sun instead of flying off.
👉 What is gravity and motion (inertia)?
This model is accepted today by scientists.
👉 What is the heliocentric model?
Scientific theories can change when new ______ is discovered.
👉 What is evidence?
This property determines if a planet can support life.
👉 What is atmosphere?
A small planet like Pluto is called this.
👉 What is a dwarf planet?
If distance between two objects increases, gravity becomes…
👉 What is weaker?
The geocentric model failed because it could not explain…
👉 What is planetary motion (retrograde motion)?
This is the difference between a law and a theory.
👉 What is: a law describes, a theory explains?
This planet is farthest from the Sun and very cold.
👉 What is Neptune?
Objects with less density than water will…
👉 What is float?
This explains how planets formed from gas and dust due to gravity.
👉 What is the solar nebula theory?
This scientist supported the heliocentric model.
👉 Who is Copernicus? (Galileo is also acceptable)
This explains why objects fall toward Earth.
👉 What is the theory of gravity?
This affects how fast a planet orbits the Sun.
👉 What is distance from the Sun?
A well-tested explanation that can change over time.
👉 What is a scientific theory?
