What is Hubble’s Law?

• Sound from space proves the big bang

• The further away an object is, the faster it is moving

• Light elements make up the entire universe

• Starlight is moving toward us...blue shift.

Where were the heavier elements formed?

• Inside Stars

• supernovas

• Inside the sun

• Big Bang

How is a star formed?

• A nebula comes together by accretion and starts to burn

• Rocks start to burn because of pressure

• Accretion makes space dust fall apart

• nebulas come together and explode

New stars have been observed in the remains of exploded stars. What are the new stars made of?

• light particles from Earth

• ice crystals

• The old stars

• Only the heavy elements

Why did people change their mind from a geocentric solar system model to a heliocentric solar system model?

• Observation of the galaxy

• The Greeks studied stars more in depth

• Old leaders of the church passed away

• Improved technology helped us understand the universe much better

When we launched the Hubble Space Telescope, it changed our ideas about the size and magnitude of the Universe. What phrase best describes what happened in this example?

• All scientific discoveries happen on accident

• New technology leads to new discoveries

• All scientific ideas will one day be proven false

• We discover more things when we know where to look

What is accretion?

• When a star begins fusion and creates new elements.

• When energy from a star makes it start burning.

• When dust and gas in space begin to stick together due to gravity.

• When planets are attracted to each other and collide.
