Gravity: Pulling Things Down

Active, hands-on exploration works for this topic because gravity is a force students feel but cannot see. Through repeated dropping and observing, children build the vocabulary and mental model they need to name what is happening every time an object falls.

• Common Core State Standards
• NGSS: K-PS2-1: Plan and conduct an investigation to compare the effects of different strengths or different directions of pushes and pulls on the motion of an object.
• NGSS: K-PS2-2: Analyze data to determine if a design solution works as intended to change the speed or direction of an object with a push or a pull.

Activity 01

• Inquiry Circle
• 25 min · Small Groups

Inquiry Circle: Drop Test Lab

Small groups receive five objects: a crumpled paper ball, a flat piece of paper, a block, a feather, and a cotton ball. They drop each from the same height and observe whether they reach the floor at the same time or at different times, then sort them into fast fallers and slow fallers.

Predict what happens when you drop different objects from the same height.

Facilitation Tip

During the Drop Test Lab, have each pair use the same four objects in the same order so the class can compare results side by side.

What to look for

Give each student a small card. Ask them to draw one object falling and label the direction it is going. Then, ask them to write one word that names the force pulling it down.

Activity 02

• Think-Pair-Share
• 15 min · Pairs

Think-Pair-Share: What If Gravity Stopped?

Ask students to imagine what would happen in their classroom if gravity turned off for one minute. After pairs share ideas about floating pencils and drifting lunch boxes, bring it back to what is actually keeping all those things on the floor right now and what that force is called.

Explain why a ball always falls to the ground when you let it go.

Facilitation Tip

In the Think-Pair-Share, limit the ‘think’ time to 15 seconds so students stay engaged and the share feels purposeful rather than random.

What to look for

Hold up two different objects (e.g., a block and a soft toy). Ask students: 'What do you predict will happen when I let go of both at the same time from this height?' After dropping them, ask: 'What did you observe? Why do you think they both went down?'

Activity 03

• Gallery Walk
• 15 min · Pairs

Gallery Walk: Gravity in Action

Post six large photos showing gravity at work: a waterfall, a fallen leaf, a bouncing ball's arc, rain falling, a person sitting in a chair, and a spilled cup. Students walk with a partner and place a sticky note marked G on each photo where gravity is pulling something downward.

Compare how gravity affects a feather and a rock.

Facilitation Tip

On the Gallery Walk, provide clipboards so students can record observations without losing their place as they move.

What to look for

During a classroom activity where students drop objects, walk around and ask individual students: 'Show me an object that is being pulled down by gravity. Tell me why it is moving down.'

A few notes on teaching this unit

Teachers approach this topic by anchoring every explanation in the child’s lived experience—letting go of toys, pencils, or crumpled paper—and naming what they just felt. Avoid abstract explanations about mass or distance; instead, use consistent language like ‘down’ and ‘pull’ to build a stable concept. Research shows that repeated, short trials with immediate discussion solidify understanding better than single demonstrations.

By the end of these activities, students will confidently state that gravity pulls objects down, point to the ground as the consistent direction, and use the word gravity to explain why dropped items fall. They will also recognize that the pull happens everywhere, indoors and out, and works on all objects regardless of weight or material.

Watch Out for These Misconceptions

• During the Drop Test Lab, watch for statements that gravity only pulls heavy things down.

  Prompt students to crumple one piece of paper tightly and leave another flat, then drop both together. Ask: ‘Which one felt gravity more? Why did the flat one take longer to land?’ This highlights that air slows some objects, but gravity pulls all of them down.

• During the Gallery Walk, watch for comments that gravity only works outside.

  Ask students to point to objects in the room as they walk and say aloud: ‘Gravity pulls this pencil down right here.’ Reinforce that gravity works inside the classroom, outside, and everywhere on Earth.
