Paper Plane Investigators

Overview

Students explore how forces affect flight by designing, testing and improving paper planes. Working in small teams, they change one feature at a time, measure flight distance, record results and use evidence to explain the roles of lift, thrust, drag and gravity.

Learning intentions

• We are learning to identify the main forces acting on a flying paper plane.
• We are learning to make a fair test by changing one design feature at a time.
• We are learning to record measurements and use evidence to improve a design.
• We are learning to communicate scientific ideas using flight vocabulary.

Success criteria

• I can name and show the direction of lift, thrust, drag and gravity.
• I can change one part of a paper plane and keep other parts the same.
• I can measure and record flight distances in a table.
• I can use my results to describe which design worked best and why.

Curriculum links

• Key competencies — thinking, managing self, participating and contributing, and relating to others.

Lesson structure (60 minutes)

1. 0–7 min · Hook and wonder. Open with the opening flight challenge slide showing two contrasting paper planes and ask, “Why might one fly farther than the other?” Students silently predict, then share ideas with a partner. Establish a safe testing area and explain that planes are launched away from people, never at faces.

2. 7–15 min · Build shared knowledge. Use the forces and flight slides to demonstrate a gentle paper-plane launch and introduce four forces: thrust is the push forwards; drag is air resistance pushing backwards; gravity pulls down; and lift is the upward force that helps a plane stay in the air. Students use their hands to show each direction and add arrows to a quick teacher model. Clarify that a hand provides thrust, while the plane’s shape helps it create lift.

3. 15–23 min · Design and predict. Place students in five teams of four. Give each student one sheet of paper and demonstrate a simple plane fold, using the folding and fair-test instruction slides. Students make a basic plane, name their team and agree on one design change to investigate: wing shape, a fold, or a small added paper weight. Before testing, teams predict whether the change will increase or decrease distance and explain why.

4. 23–40 min · Test and record. Distribute the paper-plane investigation sheet. In a clearly marked lane, each team completes three trials of the basic design and three trials of the changed design. One student launches from the same line, one measures from the line to where the plane first lands, one records the distance in centimetres, and one observes whether the plane turns, stalls or dives. Students swap roles after each trial. Pause halfway to ask teams to check: “Have we changed only one feature? Are we measuring in the same way?”

5. 40–50 min · Improve through evidence. Teams compare their results and circle the design with the greater typical distance. They make one careful improvement based on their evidence, such as adjusting a wing fold or balancing the added weight, then complete one final test. Students add the final result and a short explanation to the results and improvement section.

6. 50–57 min · Team findings. Use the findings-sharing slides to prompt brief team reports. Each team shares its design change, one result, and a conclusion using at least three words from this list: lift, thrust, drag, gravity, distance, fair test, evidence. List common patterns and surprising results on the board; highlight that a single test is less reliable than repeated trials.

7. 57–60 min · Plenary and check. Return to the final reflection slide. Students complete the final sentence on the exit reflection: “Our change affected flight because…” and draw arrows for two forces on their plane. Invite two or three students to share before collecting sheets.

Resources

• Plain A4 paper, three sheets per student
• Pencils, rulers or tape measures
• Five clearly marked flight lanes
• Masking tape for launch lines and landing areas
• Five small paper scraps or paper clips for optional added weight
• Board and marker
• the paper-plane flight investigation slide deck
• the paper-plane investigation sheet
• Safety goggles if required by school procedures

Assessment

• Listen during the hook and force demonstration for correct ideas about pushes, pulls and force directions; correct the misconception that heavier planes always fly farther.
• During testing, check that teams change one variable, use the same launch line and record measurements accurately.
• Collect the worksheet as an exit assessment. Look for labelled force arrows, a completed comparison table and a conclusion supported by at least one result.

Differentiation

• Provide a pre-folded example, picture instructions and a word bank with arrows for lift, thrust, drag and gravity. Use the visual instruction step cards for students who benefit from step-by-step visual prompts.
• Give sentence starters: “We changed…”, “Our evidence shows…”, and “The plane travelled farther because…”. Pair EAL learners with supportive peers and model each term with gestures.
• Allow students with fine-motor or coordination needs to work with a partner, use a partially folded plane, measure with a partner, or contribute as recorder or observer.
• Extend confident learners by asking them to calculate the difference between the two designs, compare consistency across three trials, or explain why a plane may travel far but stay in the air for less time.
