Gravity Forces
Grade 5 - Science - On Level
Which force explains this situation: water flows down a stream channel?
- gravity pulls water from higher ground to lower ground
- gravity pulls the marble downhill
- gravity pulls the rope back toward Earth
- gravity pulls water drops toward Earth
Which evidence supports a gravity explanation for this situation: a dropped pencil lands near a student's foot?
- the rope rises briefly, then falls back down
- the ball accelerates toward the floor
- the pencil falls even without being pushed down
- drops move downward when they become heavy enough
Why is this explanation weak: "the marble moves because it has no force acting on it"?
- it correctly names Earth's pull
- it does not match the gravity model or the observed motion
- it explains a downward force
- it uses evidence from falling motion
Which claim matches the gravity evidence in "a ball rolls off a desk and falls to the floor"?
- objects fall only when pushed by air
- gravity works only during storms
- Earth's gravity pulls objects downward toward Earth
- gravity pushes everything away from Earth
What question belongs in a gravity investigation about "rain drops fall from a cloud"?
- Which solution dissolves salt?
- Which source has the best heading?
- How does Earth's pull affect unsupported objects?
- Which organism is a producer?

Which evidence supports a gravity explanation for this situation: a ball rolls off a desk and falls to the floor?
- the ball accelerates toward the floor
- the pencil falls even without being pushed down
- the marble moves faster as the ramp slopes downward
- drops move downward when they become heavy enough
Why is this explanation weak: "clouds pull drops upward forever"?
- it does not match the gravity model or the observed motion
- it correctly names Earth's pull
- it uses evidence from falling motion
- it explains a downward force
