Rocket Adventures

Overview

Students explore how rockets move by observing, predicting, and testing pushes and pulls. Through a balloon rocket investigation, they connect the force of escaping air with movement and begin using simple science language to describe what they notice.

Learning intentions

• WALT identify a rocket as an object that can move through the air.
• WALT explore how a push or pull can change the movement of an object.
• WALT make a prediction, observe carefully, and share what we notice.
• WALT use words such as push, pull, move, fast, slow, up, and down.

Success criteria

• I can show or describe a push and a pull.
• I can make a prediction about how a balloon rocket will move.
• I can observe and talk about what happened.
• I can draw or explain one way a rocket moves.

Curriculum links

• Physical Science — Motion and Forces: predicting and testing how pushes and pulls affect the movement of objects, including rockets.
• Physical Science — Motion and Forces: noticing how the size or direction of a force changes movement.
• Science capabilities: engaging with science, gathering and interpreting evidence, and communicating findings.
• Key Competencies: thinking; using language, symbols, and texts; participating and contributing.

Lesson structure (40 minutes)

1. 0–5 min · Rocket hook. Display a picture of a rocket launching and open with the rocket launch introduction. Ask, “What do you think makes a rocket move?” Students use their bodies to pretend to blast off, then share ideas with a partner. Accept all initial explanations and introduce rocket, force, push, and move.

2. 5–10 min · Pushes and pulls. Demonstrate gently pushing a toy car and pulling it with a piece of string. Revisit the push-and-pull examples and ask students to show with their hands whether each example is a push or a pull. Explain that a force is a push or pull that can make something move, stop, or change direction. Students practise saying, “A push/pull made the object move.”

3. 10–15 min · Predict the balloon rocket. Show the balloon, straw, string, and tape without releasing it. Ask, “What might happen when the air comes out?” Students turn and talk, then draw a quick prediction on the balloon rocket prediction sheet. Invite two or three children to explain their drawings. Emphasise that scientists make predictions that can be tested; predictions do not have to be correct.

4. 15–28 min · Balloon rocket investigation. Before the activity, remind students to keep balloons away from faces, never put balloons in mouths, and wait for an adult to help with tying or releasing. In groups of four, students take roles: equipment helper, balloon holder, observer, and speaker. The teacher or an adult threads a straw onto a long string, tapes an inflated balloon to the straw, and holds the balloon closed. Students predict which direction it will travel. Release the balloon and repeat once or twice, changing only the amount of air if practical. Students observe, take turns, and record or draw what happened on the balloon rocket observation section. Pause between trials to ask, “Which way did the air go? Which way did the balloon go?”

5. 28–34 min · Share the evidence. Gather students with their worksheets. Reopen the investigation discussion slides and invite groups to demonstrate the direction of the balloon’s movement using an arm arrow. Co-construct a simple explanation: “Air rushed out one way, and the balloon moved the other way.” Avoid expecting formal Newton’s law terminology, while highlighting that the escaping air provides a push.

6. 34–40 min · Plenary and check. Display the final rocket recap. Students complete the sentence, “A rocket moves when…” with a partner, then draw a rocket and add an arrow showing its movement on the worksheet. Choose several students to share. Finish with a whole-class action sequence: crouch, count down, point in the direction of the rocket, and say, “Push makes it move!”

Resources

• the rocket investigation slide deck
• the balloon rocket prediction and observation sheet
• Balloons, one or two per group
• Drinking straws, one per group
• Long lengths of smooth string or fishing line
• Sticky tape
• Chairs or tables for securing the string
• Optional toy car and string for demonstrating push and pull
• Safety scissors and adult support for preparation

Assessment

• Listen during the hook and push-and-pull activity for students who can identify or demonstrate a force.
• During the investigation, check whether students make a prediction, observe the direction of movement, and use evidence words such as “I saw” or “It moved”.
• Review the final drawing and sentence on the worksheet. Confer with students who show movement but cannot yet connect it to a push from escaping air.

Differentiation

• Support oral language with actions, picture cues, and sentence starters: “I predict…”, “I saw…”, and “The balloon moved…”.
• Pair children strategically and provide adult assistance with inflating, tying, taping, and releasing balloons. Students who are sensitive to loud noises may observe from further away or use a quieter demonstration.
• Offer drawing, pointing, acting, or oral explanation as alternatives to writing. Scribe children’s ideas where needed.
• Extend confident learners by asking them to compare a balloon with more air and less air, predict which will travel further, and explain what evidence supports their idea.
• For EAL learners, model each key word with a gesture and repeat the same sentence pattern throughout the lesson.
