Mikaela, a skydiver, jumps out of airplanes with a parachute so that she can land safely on the ground. She has jumped out of airplanes many times from different heights in the sky. The arrows show which direction Mikaela falls each time she jumps. What does this tell you about gravity?

• Gravity changes direction with height.

• Gravity never changes direction.

• Gravity increases with height.

• Gravity decreases with height.

Mikaela is doing an experiment on an airplane. She drops a tennis ball, a feather, a paper clip, and a magnet to see what happens. The arrows show the direction each object falls. What does this tell you about gravity?

• Gravity only pulls on heavy objects.

• Gravity only pulls on light objects.

• Gravity only pulls on magnetic objects.

• Gravity pulls on all objects.

Mikaela has jumped out of airplanes all over the world. What does the direction she falls tell you about gravity?

• Gravity has no pattern. The direction it pulls objects is always different.

• Gravity has a pattern. The direction it pulls objects is always “down” when down means toward the center of the Earth.

• Gravity only pulls objects “down” toward the surface of the Earth in certain locations.

• Gravity always pulls objects “down” toward the surface of the Earth, no matter the location.

Andres is a new skydiver. What can he claim is evidence of gravity?

• Jumping out of an airplane and floating.

• Jumping out of an airplane and falling to the ground.

• Jumping out of an airplane and staying in the air.

• Jumping out of an airplane and moving sideways.

If skydiving isn't enough to proof that gravity pulls objects towards the Earth, what other evidence could make this argument stronger?

• Jumping from different heights and observing the fall.

• Jumping from the same height multiple times.

• Observing other objects falling to the ground.

• All of the above.
