Evidence for the Big Bang Theory
100

All evidence in science is based on these, which are specific, sensory, and scaled statements that come from one of our 5 senses.

What are observations?

100

Observations that use numbers are called this.

What is quantitative?

100

The this of light can tell us the energy and color of that light.

What is wavelength?

100

These two elements are the lightest on the periodic table and make up most of the universe.

Hydrogen and helium

200

This is a process used to understand our natural world and solve problems through observation and experimentation.

What is science?
200

This is another word for information.

What is data?

200

This is the study of wavelengths of light in order to gather information. 

What is spectroscopy?

200

Hydrogen and helium's abundances in the universe are evidence that the universe was really this at the beginning.

What is hot?

300

This is the description of an observation that helps us remember that the more detail an observation has, the better.

What is specific?

300

These allow us to compare against a standard unit, which means we can all understand the information in the same way.

What is measurement?

300

This includes all energies of light, from radio all the way to gamma.

What is the electromagnetic spectrum?

300

If a star's light is redshifting, it means that the star is doing this.

What is moving away from us?

400

Sir Isaac Newton's explanation of why all apples fall from the tree is an example of a this.

What is a theory?

400

List the name, tool, and base unit for the following measurement: how much space something takes up.

What is volume, beaker/flask/graduated cylinder/, liter

400

A fluorescent bulb gives off this, because it is a tube of energized gasses.

What is an emission spectrum? 

400

Redshifting is evidence that the universe is doing this.

What is expanding from a single point?

500

If I am setting up controlled situations in order to test a theory that I have, I am performing these.

What are experiments? 

500

If I am measuring on a scale, what is the name, definition, and base unit for the measurement I am taking?

What is mass, how much matter something contains, gram?

500

Each element gives off different light because of the unique number of these things within its atom.

What are protons, neutrons, and electrons

500

Hubble's constant allows us to tell this about the universe.

What is the age of the universe?
