Force and Motion
This force holds all of the objects in the solar system in orbit around the Sun.
What is the force of gravity
Together, this group of objects has one star, 8 planets, and a variety of moons and asteroids.
What is the Solar System
This is the scientific name for layers of rock
strata
Change over time
What is evolution
This is the highest point on a wave
Crest
This is what we call two forces are equal and opposite of each other.
This is the galaxy in which our solar system is located.
What is the Milky Way Galaxy.
Finding one of these in the rock strata can tell you about the environment that once existed there, the age of the layer, and a bit about the kind of life that once lived there.
What is a fossil
This process occurs in nature and is also known as survival of the fittest. It allows animals that are well adapted to survive longer and reproduce more.
What is natural selection
What is the wavelength
This is the unit that we use to measure force. It is named for the guy who invented the laws of motion.
What are Newtons
This is the theory of how our universe began.
What is the Big Bang Theory
This is the approximate age of Earth
4.6 billion years
Examples of this process include gene editing and selective breeding. It is the process that occurs when humans intervene with evolution.
What is artificial selection.
The particles in a wave simply move up and down, instead waves are transferring this through them.
What is energy.
This is the number of laws that Newton discovered that describe force and motion. Together they are called Newton's Laws of Motion.
There are many different kinds of these objects that form from clouds of gas and dust. Types include elliptical, spiral, irregular, and barred spiral.
What are Galaxies
This geologic formation has formed over billions of years and is a great place to travel and explore Earth's geologic history through the layers you can see there.
These organisms were famous for being studied right after the industrial revolution. They helped prove the theory of natural selection as researchers watched the dark colored versions begin to survive better than the light colored versions.
This includes gamma rays, radio waves, visible light, ultraviolet light, infrared light, and microwaves.
What is the electromagnetic spectrum.
When forces are unbalanced, we can expect that an object will begin doing this.
What is motion (moving).
Based on advanced physics and mathematic calculations, we can tell our universe is about this many years old.
13.8 billion years.
This geologic law states, "the lower you go, the older it gets."
What is the law of superposition
When two organisms have anatomic and embryonic similarities, they likely shared one of these at some point in their evolutionary history.
What is a common ancestor.
Mechanical waves require this to travel. Examples could include air or water.
What is a medium.
