8.E.4B.2 Construct explanations for how gravity affects the motion of objects in the solar system and tides on Earth.

Open Ended

How does gravity affect the motion of the planets?

Multiple Choice

Spring tides are caused by __.

• The sun, moon and Earth's alignment during a new moon

• The sun, Earth, and moon's alignments during a full moon

• the combined gravitational pull of the moon and the sun on Earth's waters

• All of the above

8.E.4B.3 Develop and use models to explain how seasons, caused by the tilt of Earth’s axis as it orbits the Sun, affects the length of the day and the amount of heating on Earth’s surface.

Multiple Choice

Where are the sun's rays most direct?

• The North pole

• The Equator

• The South pole

Multiple Choice

True or false: If it is winter in the northern hemisphere, it is also winter in the southern hemisphere.

• True

• False

8.E.4B.4 Develop and use models to explain how motions within the Sun-Earth-Moon system cause Earth phenomena (including day and year, moon phases, solar and lunar eclipses, and tides).

• 1 day

• 1 month

• 1 year

• 1 season

Multiple Choice

A new moon occurs when?

• When the sun is between the Earth and the moon.

• When the Earth is between the sun and the moon.

• When the moon is between the Earth and the sun.

• When the sun, Earth, and moon are at right angles with each other.

8.E.4B.5 Obtain and communicate information to describe how data from technologies (including telescopes, spectroscopes, satellites, space probes) provide information about objects in the solar system and the universe.

Multiple Choice

Where is the best place to get pictures of stars.

• Downtown Atlanta.

• out in the country in a hay field.

• on a mountain top.

• from outer space

Multiple Choice

Which of the following would be used to collect soil samples on Mars?

• a space shuttle

• a spectroscope

• a space probe

• a satellite

Multiple Choice

What is the best use for a spectroscope?

• measuring and calculating distance

• analyzing chemical composition

• measuring speed

• measuring size

a spectroscope or spectrometer — breaks the light from a single material into its component colors the way a prism splits white light into a rainbow. It records this spectrum, which allows scientists to analyze the light and discover properties of the material interacting with it.
