1.)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.

2.)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?

A.) All matter and energy were contained inside the small point.

B.) Matter and energy came from areas of the universe and were attracted to the small point.

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

D.) Matter was considered into a single point until energy was attracted to the matter from dark areas of the universe.

3.) Why do scientists believe the universe is still expanding?

A.) The further away from an object is, the temperature and pressure eventually become, causing nuclear fusion.

B.) Distant object shift in frequency toward red on the electromagnetic spectrum, which tells us objects are moving away from us.

C.) Spiral galaxies spin, so they appear to be a rotating disk of stars and dust.

D.) Distant objects shift in frequency toward blue on the electromagnetic spectrum, which tells us objects are closer to us .​
