Define, Describe and explain The Red shift in your own words.

Multiple Choice

Students are using balloons to describe the expanding universe model. The students blow up several balloons and put them on the floor. Each balloon represents a different galaxy. How should the students move or change the balloons to demonstrate how the universe is expanding?

• All of the balloons should be moved to the center of the floor.

• Each balloon should be inflated more so that they are all increasing in size.

• Each balloon should be deflated so that there is more distance between the surface of each balloon.

• All of the balloons should be moved away from each other so there is more distance between them.

Redshift:
Every object in the universe is moving away from every other object in the universe.

The universe is Expanding.

After watching the next video, be prepared to answer this question.

What evidence do scientist use to support the Big Bang Theory?

Stars or Galaxies moving away from us is known as a Red Shift.

Stars or Galaxies moving towards us is known as a Blue Shift.

Explain using the Doppler Effect how these names have been given in each case.

In the textbook, Read pages 410-411.

Multiple Choice

Evidence gathered by studying the composition and movement of distant galaxies indicates that the universe expanded rapidly from a single small point. The universe has continued to expand for over 13 billion years.

Which statement is in agreement with the current understanding of the expanding universe?

• All matter and energy were contained inside the small point.

• Matter and energy came from dark areas of the universe and were attracted to the small point.

• Matter and energy fell into the small point the same way a black hole attracts matter and energy.

• Matter was condensed into a single point until energy was attracted to the matter from dark areas of the universe.

Multiple Choice

When an object is moving away from us, the waves are stretched out, resulting in a longer wavelength and lower frequency.

• Blue Shift

• Red Shift

• Wavelength

• Frequency
