Which historical figure provided evidence that Copernicus' astronomical model of our solar system was correct by using a telescope?

• Newton

• Plato

• Galileo

• Ptolemy

A pool stick hits the purple pool ball with a force of 2N causing it to collide with only one of the white cue balls. Which of the following statements is true?

• 100% of the energy will remain with the purple pool ball.

• The white cue ball that was not struck will receive 1N of force.

• An energy transfer will occur between the purple pool ball and the white ball that was hit.

• The white cue ball that was struck by the purple pool ball will receive 3N of new force.

Why is the Sun the brightest star humans can see without using a telescope?

• because it is the largest star

• because it is the closest star

• because it is made up of hot gases

• because it produces light energy

Who arrives at the bottom first and why?

• Victoria arrives first because she has the least amount of mass, making friction affect her less.

• Victoria arrives first because she has the least amount of mass, making gravity affect her more.

• Juan arrives first because he has the greatest amount of mass, making friction affect him less.

• Juan arrives first because he has the greatest amount of mass, making gravity affect him more.

Jesse, who has more mass than Victoria but less than Thomas, joins the friends for a second trip down the slide. What is the order the friends will reach the bottom?

• Juan, Thomas, Jesse, Victoria

• Jesse, Victoria, Thomas, Juan

• Victoria, Jesse, Thomas, Juan

• Victoria, Juan, Jesse, Thomas

What is the highest tide height recorded on the chart for 12/22?

• 10.36 feet

• 11.55 feet

• 6.6 feet

• 5.5 feet

The chart is reporting the large changes in the tides of Milbridge, Maine. Scientists now know that these changes in water depths (tides) observed on the coastline are due in part to the [CHOICE 1].

• A) Moon's orbit around the Earth

• B) Sun's influence on surface temperatures

• C) Moon's rotation on its axis

• D) Earth's axial tilt

Which of the following statements, in terms of the ice block, is correct? A. Decreased air temperature will cause the molecules to slow down, changing the ice from a solid to plasma. B. Increased solar energy will cause the molecules to move faster, changing the ice from a solid to a liquid. C. Greater gravitational force will cause the molecules to increase so much that the ice block will change from a solid to a gas. D. Lower air pressure will cause the molecules to become more compacted, which begins the melting process.

They organized the organisms they observed into the below table: Organism: Grass, Energy Source: Sun; Organism: Mouse, Energy Source: Grass, Grasshoppers, Dragonflies; Organism: Dragonfly, Energy Source: Ants; Organism: Snake, Energy Source: Mice, Frogs; Organism: Owl, Energy Source: Snakes, Frogs, Mice. Which of the following food chains show the correct energy flow? A. Owl -> Snake -> Mouse -> Grass B. Mouse -> Dragonfly -> Owl C. Grass -> Mouse -> Snake -> Owl D. Grass -> Snake -> Owl

• A. Owl -> Snake -> Mouse -> Grass

• B. Mouse -> Dragonfly -> Owl

• C. Grass -> Mouse -> Snake -> Owl

• D. Grass -> Snake -> Owl

Which of the following would be the best example of a solution? A. A pet shop adding rocks and grass to the bottom of a fish tank. B. A hiker creating a trail mix made of nuts, dried berries, and M&Ms. C. A boy tossing a salad’s ingredients before adding the dressing. D. A person mixing blue and yellow paint to make green paint.
