Science stuff
This term describes a testable explanation for an observation
Hypothesis
Nebula
This early model of the universe placed Earth at the center
geocentric model
Our sun is at the center of our galaxy in this model.
Heliocentric
These orbit planets and are naturally occuring
moons
What is an independent variable?
The core
This model correctly states that the Sun is at the center of the solar system.
heliocentric model
This is the brightest star to us but has a low luminosity compared to other stars.
The sun
This is anything that orbits a planet.
Satellites.
What you change
This layer of sun is just outside the core.
The Radiative zone.
What technology did we use to help develop the heliocentric model?
Telescope
Planets orbit these.
Stars
This is when a sun is covered by the moon
Solar eclipse
What is Kinetic energy?
Energy in motion
This is like a solar flare but held together by magnetic fields and is always present.
Prominence
This term describes the backward‑looking motion of planets like Mars, which the heliocentric model explains easily.
What is retrograde motion.
This is a sudden burst of energy from the sun.
Solar flare.
The moon is in orbit because of this.
Gravity.
What is the formula for calculating density?
D=m/v
List 4 layers of the sun
Core
Radiative Zone
Convective Zone
Photosphere
Chromosphere
Corona
In the heliocentric model, this force keeps planets orbiting the Sun
Gravity.
The sun is at different angles in the sky because of this.
Earths axial tilt change its orientation in the sky.
Tidal forces.
