This Grade 3 science worksheet challenges students with gravity and free-fall scenarios. Four multiple choice items compare marbles, baseballs, feathers, and rubber balls to test whether mass changes fall rate when air is ignored. Five fill-in blanks review gravity, Earth, air resistance, and same rate. Examples use Grade 3 classroom settings like dropping a ball from a window. The worksheet aligns with NGSS 3-PS2 and helps students explain why all objects fall at the same rate.
Style:
Forces and Motion
Part A: Multiple Choice
Circle the best answer for each question.
1. A Grade 3 student drops a marble and a baseball from the same height with no air effect. Which hits the ground first?
A) The marble hits first
B) The baseball hits first
C) They hit the ground at the same time
D) Neither one falls
2. Why does a feather fall more slowly than a rock in real life?
A) Gravity is weaker on feathers
B) Air resistance pushes up on the feather more
C) Feathers are not pulled by gravity
D) Rocks have special magnets
3. A ball is dropped from a Grade 3 classroom window. What makes it fall?
A) A magnet in the ground
B) The force of gravity from Earth
C) The wind only
D) Friction with the window
4. Two Grade 3 students drop different-sized rubber balls at the same time. What happens?
A) The heavier ball lands much sooner
B) The lighter ball lands much sooner
C) They land at about the same time
D) Both balls float in the air
Part B: Fill in the Blank
Write the correct answer on each line.
1. The force that pulls objects toward Earth is called gravity.
2. Ignoring air, two objects dropped from the same height fall at the same rate.
3. A feather falls slowly because of air resistance pushing up on it.
4. Gravity always pulls objects toward the center of Earth.
5. Without gravity, a Grade 3 student's jump would never bring them back down.
