Gravity Forces
Grade 5 - Science - Challenge Me
Which force explains this situation: water flows down a stream channel?
- gravity pulls water from higher ground to lower ground
- Earth's gravity pulls the ball downward
- gravity pulls the marble downhill
- Earth pulls the pencil toward its center
Which evidence supports a gravity explanation for this situation: rain drops fall from a cloud?
- water moves downhill along the channel
- drops move downward when they become heavy enough
- the ball accelerates toward the floor
- the rope rises briefly, then falls back down
Why is this explanation weak: "clouds pull drops upward forever"?
- 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 jump rope returns to the ground after being tossed"?
- gravity pushes everything away from Earth
- Earth's gravity pulls objects downward toward Earth
- gravity works only during storms
- objects fall only when pushed by air
What question belongs in a gravity investigation about "a ball rolls off a desk and falls to the floor"?
- Which solution dissolves salt?
- How does Earth's pull affect unsupported objects?
- Which organism is a producer?
- Which source has the best heading?
Which force explains this situation: a dropped pencil lands near a student's foot?
- Earth pulls the pencil toward its center
- gravity pulls the marble downhill
- Earth's gravity pulls the ball downward
- gravity pulls the rope back toward Earth
Which evidence supports a gravity explanation for this situation: a jump rope returns to the ground after being tossed?
- drops move downward when they become heavy enough
- the marble moves faster as the ramp slopes downward
- the rope rises briefly, then falls back down
- the ball accelerates toward the floor
Why is this explanation weak: "the desk pushes the ball upward after it leaves"?
- it correctly names Earth's pull
- it explains a downward force
- it does not match the gravity model or the observed motion
- it uses evidence from falling motion
Which claim matches the gravity evidence in "a marble speeds up while rolling down a ramp"?
- Earth's gravity pulls objects downward toward Earth
- gravity pushes everything away from Earth
- gravity works only during storms
- objects fall only when pushed by air
What question belongs in a gravity investigation about "a jump rope returns to the ground after being tossed"?
- Which source has the best heading?
- Which solution dissolves salt?
- Which organism is a producer?
