Big Bang Research Activity

What happens if you reverse the galaxy motion and go back in time?

• Everything must have been condensed into one extremely dense point
• Everything would still be where it is today
• Some things would remain, some would have moved back
• Nobody has a clue

What happens to the electrons of an atom when they get energized?

• They move to lower energy levels
• They move permanently to higher energy levels 
• They move temporarily to higher energy levels
• They fly off the atom completely

What happens when the electrons fall back to lower energy levels?

• They release protons and neutrons
• They lose energy in the form of light
• They gain energy bounce back
• They lose energy and go completely dark

When analyzing star light or elements in a lab, what are the different color patterns produced by the prism called?

• emission spectra

• the rainbow

• absorption spectra

• spectral rainbow

What happens to the waves in front of the moving object?

• Nothing happens to the waves
• The waves spread out (or elongate)
• They crash into each other
• The waves bunch up (or compress)

What happens to the waves behind the moving object?

• Nothing happens to the waves
• The waves spread out (or elongate)
• They completley disappear
• The waves bunch up (or compress)

What does CMBR stand for?

• Cosmic Microns Background Radiation
• Comic Members Building Roads
• Cosmic Microwave Background Resistance
• Cosmic Microwave Background Radiation

Where in the electromagnetic spectrum can CMBR radiation be found?

• In the microwaves section
• In the radio waves section
• In the Infrared section
• In the Gamma Rays section

What happened to the electromagnetic radiation emitted from the Big Bang?

• It is visible in optic telescopes

• It has moved to the gamma ray part of the spectrum

• It has stretched out to the microwave part of the spectrum

• It is too old and no longer exists

How do scientists know what stars are made of?

• The Doppler Effect

• Emission Lines

• Radio Waves

• The Electromagnetic Spectrum
