Balloon Rocket STEM Challenge

Balloon Rocket STEM Challenge (9‑Point Engineering Graph)

A hands‑on STEM challenge where learners build and test two different balloon rockets to explore force and motion. Students compare how far each rocket travels using the 9‑Point Engineering Graph, sketch their designs, and record how they built each version. This activity is low‑prep, highly engaging, and ideal for primary classrooms, homeschool settings, STEM centres, or makerspace stations.

WHAT’S INCLUDED:
• 3‑page STEM Challenge set: Cover Page, Instructions Page, Activity Page
• Full 9‑Point Engineering Graph for comparing two balloon rocket designs
• Clear, consistent directions designed for real classrooms
• Kid‑friendly layout that supports independent exploration
• Printable PDF (A4/Letter compatible)

TEACHER BENEFITS:
• Low‑prep activity using simple, affordable materials
• Consistent layout across all 9‑point engineering challenges
• Supports independent exploration and student‑led problem‑solving
• Flexible for whole‑class lessons, small‑group rotations, or STEM centres
• Ideal for quick engineering challenges or early finishers

LEARNING CONCEPTS:
• Engineering design process
• Planning, sketching, and comparing two designs
• Forces and motion (thrust, direction, friction)
• Testing and recording performance
• Early data collection and observation skills

HOW IT WORKS:
Students build two different balloon rockets, test how far each one travels along a string, and record their results using the 9‑Point Engineering Graph. They sketch each design, note how they built their rockets, and compare how the flight distance changed between the two trials. The challenge naturally scales: younger learners build simple rockets, while older learners experiment with balloon size, angle, and friction to improve performance.

PRINTING & PREP:
• Print pages single‑sided
• Provide simple materials such as balloons, straws, tape, and string
• Set up a clear space for launching and measuring distance
• Encourage students to sketch, label, and compare their two designs
• Adult supervision required for launching activities

AGE RANGE:
Suitable for ages 5–11 (Primary). Younger learners can participate with support.

PERFECT FOR:
• Classroom STEM centres
• Early finishers
• Makerspace stations
• Homeschool STEM time
• After‑school clubs
• Family STEM nights
