Quarter 2 Benchmark Review

Students investigated the Big Bang theory using a balloon. They added 5 dots to a barely inflated balloon to represent different galaxies in the universe. Then, they inflated the balloon and measured the distances between the dots. They discovered the dots were moving away from each other.

How does this support the big bang theory?

• As the balloon inflated, each galaxy became larger

• As the balloon inflated, each galaxy became smaller

• As the balloon inflated, each galaxy moved closer to each other

• As the balloon inflated, each galaxy moved farther away from each other

Students investigated the Big Bang theory using a balloon. They added 5 dots to a barely inflated balloon to represent different galaxies in the universe. Then, they inflated the balloon and measured the distances between the dots. They discovered the dots were moving away from each other.

What does the balloon represent in this model?

• the location of specific galaxies

• the universe expanding over time

• the universe at one moment in time

• the distance of specific galaxies from Earth

When doing an experiment, scientists determined that Galaxy F is 14.3 million lightyears away, and Galaxy G is 10.4 million light years away.

Which of these galaxies is considered faster?

• Galaxy F, because it is farther away

• Galaxy F, because it is closer

• Galaxy G, because it is farther away

• Galaxy G, because it is closer

What causes the Moon to revolve around the Earth?

• Earth's gravitational pull on the Sun

• The Sun's gravitational pull on the Earth

• Earth's gravitational pull on the Moon

• The Moon's gravitational pull on the Earth

The Sun is the largest object in the solar system. What would MOST LIKELY happen to the motion of the planets if there was no inertia to keep them in orbit around the sun?

• The planets would become stationary

• The planets would float away from the solar system

• The planets would be pulled into the Sun by the Sun's gravity

• The planets would pull the Sun toward them, splitting the Sun into smaller stars

In 1977, two space probes, Voyager 1 and 2, were launched into space about two and a half weeks apart. They traveled in a spiral direction around the outer planets on their way out of the solar system. Both probes were equipped with different pieces of technology.

What is the main purpose of space probes?

• to find other planets just like Earth

• to analyze the composition of Earth's atmosphere

• to name the new moons found around the four outer planets

• to gain a better understanding about far-away objects in space
