The Force of Gravity

Active learning helps fifth graders grasp gravity because the concept of a center-seeking force is abstract and tied to their daily experience. When students manipulate objects and observe patterns, they build mental models that connect the invisible force of gravity to concrete outcomes like falling speeds and weight differences.

• 20 min · Pairs

Think-Pair-Share: Which Way is Down?

Show students a globe with small figures attached at multiple locations: the US, Australia, Brazil, and Norway. Partners draw arrows showing the direction gravity pulls each figure and discuss what they notice about all four arrows. The class shares and identifies that every arrow points toward the center of the globe , not 'down' as a floor reference.

What keeps the oceans from falling off the Earth?

Facilitation Tip

During the Think-Pair-Share, have students point to Earth’s center on a classroom globe when describing where gravity pulls.

What to look for

Ask students to draw a picture showing an object falling towards Earth. Have them label the direction of the gravitational pull and write one sentence explaining why the object falls.

Inquiry Circle: Gravity Drop Tests

Groups simultaneously drop identical objects from the same height: a tennis ball, a crumpled paper ball, and a flat sheet of paper. They record results and work to separate the effect of air resistance from gravity, building a data-based argument about whether gravity pulls harder on heavier objects.

How does gravity affect the movement of planets in our solar system?

Facilitation Tip

For the Gravity Drop Tests, provide identical balls of different weights and ask students to predict outcomes before dropping them to highlight gravity’s consistent force.

What to look for

Pose the question: 'Imagine you are on the Moon, which has less gravity than Earth. Would you weigh more, less, or the same? Explain your answer using the terms mass and gravity.'

Structured Discussion: If Earth Were More Massive

Give students the prompt: Earth's mass doubles overnight. What happens to your weight? To the moon's orbit? To the atmosphere? Small groups build a cause-and-effect chain using what they know about gravitational force and orbital motion, then share their reasoning with the class for peer questioning.

What would happen to an object's weight if Earth's mass doubled?

Facilitation Tip

In the Structured Discussion, use a visual of Earth’s mass doubling to anchor reasoning about weight changes.

What to look for

Facilitate a class discussion using the key question: 'What would happen to an object's weight if Earth's mass doubled? How might this change affect things on Earth?' Encourage students to support their ideas with reasoning about mass and gravity.

A few notes on teaching this unit

Teach gravity by grounding abstract ideas in observable evidence. Avoid over-relying on demonstrations alone; instead, pair them with student predictions and explanations to confront misconceptions directly. Research shows that students hold onto ideas like 'heavier objects fall faster' until they see counter-evidence and discuss it with peers.

Successful learning looks like students describing gravity as a force that always pulls toward Earth’s center, not just toward the ground. They should explain why objects fall at the same rate regardless of mass and predict how changes in Earth’s mass would affect weight.

Watch Out for These Misconceptions

• During Think-Pair-Share: 'Gravity pulls things down, and down is toward the floor.'

  Use the classroom globe and mini-figures placed on different continents to have students draw arrows showing gravity pulling each figure toward Earth’s center. Ask them to compare their arrows to the classroom floor’s orientation.

• During Gravity Drop Tests: 'Heavier objects fall faster because gravity pulls harder on them.'

  Provide two balls of equal size but different weights. Have students predict which will hit the ground first, then drop them simultaneously. Use their observations to redirect their thinking to gravity’s equal acceleration.
