Simple Machines and Mechanisms STEM Challenges

Simple Machines and Mechanisms STEM Challenges

A hands‑on STEM bundle for early primary learners. This set includes six engineering activities exploring simple machines and motion using easy‑to‑find materials. All activities use the 9‑Point Engineering Graph for comparing two designs. Each challenge follows a clean, kid‑friendly layout designed for real classrooms.

ACTIVITIES INCLUDED:
• Pulley Lift
• Lever Launcher
• Popsicle Stick Catapult
• Balloon Rocket
• Parachute Drop
• Paper Spinner

WHAT’S INCLUDED:
• Six 3‑page STEM Challenge sets (Cover, Instructions, Activity Page)
• 9‑Point Engineering Graphs for all activities
• Clear, consistent directions
• Printable PDFs (A4/Letter compatible)

MATERIALS NEEDED (BY ACTIVITY):
Pulley Lift: Cup, string, scissors, tape, small objects
Lever Launcher: Craft stick, blocks, pom‑pom
Catapult: Popsicle sticks, rubber bands, spoon, pom‑pom
Balloon Rocket: Balloon, straw, tape, string, scissors
Parachute Drop: Plastic bag, string, tape, scissors, small weight
Paper Spinner: Paper, scissors, ruler, tape, straw, paper clip

TEACHER BENEFITS:
• Low‑prep activities using simple materials
• Consistent layout across all six challenges
• Supports independent exploration
• Works for whole‑class, small groups, or STEM centres

LEARNING CONCEPTS:
• Engineering design process
• Forces and motion (push, pull, lift, drag, gravity)
• Simple machines: levers, pulleys, mechanisms
• Testing and comparing two designs

HOW IT WORKS:
Students plan, build, test, and compare two designs using the 9‑Point Engineering Graph. Younger learners build simple models, while older learners create more refined mechanisms.

PRINTING & PREP:
• Print pages single‑sided
• Provide simple classroom materials
• Set up a clear testing space
• Adult supervision required for height, motion, or small‑object activities

AGE RANGE:
Ages 5–11 (Primary)

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