Hey science enthusiasts! Imagine you're in a classroom with Brady, Lucas, and Kori. Which is the BEST question you could ask to gather evidence supporting the heliocentric model of our solar system?

• Do stars go around the sun?

• Why does the sun rise and set each day?

• Does the moon change its shape each month?

• Why does Venus go through phases like our moon?

Hey Vander, Evan, and Misha! Did you know that over time, scientists have changed their model of our solar system? It has transitioned from

• a Sun-centered to a Moon-centered model.

• a Sun-centered to an Earth-centered model.

• an Earth-centered to a Sun-centered model.

• a Moon-centered to an Earth-centered model.

Hey students! Imagine you're in a cosmic debate club with Yoli, Caleb, and Eli. For what reason did the heliocentric model of the universe replace the geocentric model of the universe?

• The geocentric model no longer predicted the positions of the constellations.

• The heliocentric model proved that the Earth rotates.

• The heliocentric model provides a simpler explanation of the motions of the planets.

• The geocentric model did not predict the phases of the moon.

Elif, Julius, and Lily are on a space adventure! Based on the data in the table, which planet has the ability to support life?

• A. Planet A because it is the closest to the sun and its surface temperature allows water to be a gas.

• B. Planet B because its distance from the sun allows a temperature for water to change states.

• C. Planet C because it is far enough away from the sun to allow water to exist as a liquid.

• D. Planet D because it is the farthest away of all the planets where water will only exist as solid.
