Which would properly model how the universe expands?

• Place paper clips on the ground to represent galaxies, then keep adding more and more paper clips.

• Use balloons laid on on the floor to represent galaxies, then increase the space between the balloons to show how space is expanding.

• Use a string with beads on it to represent the galaxies, then continue to add more beads.

• Fill up a cup with water to represent space, then place glitter in the water to represent galaxies, and allow the glitter to sink to the bottom to show them coming together.

In which scenario would a planet have the HIGHEST acceleration?

• When it is closest to the Sun.

• When the gravitational force of the Sun is low.

• When it crashes into another planet.

• When the moon's gravity is pulling on its oceans creating tides.

Which of the following correctly describes spring and neap tides?

• Spring tides only occur during a full moon, neap tides only occur during a new moon.

• Spring tides occur when the Earth, moon, and sun are in a straight line, while neap tides occur when the moon and sun form a ninety degree angle with the Earth.

• Spring tides have less of a difference in its high and low tides compared to neap tides.

• Spring tides cause high tides and neap tides cause low tides.
