YOUR FIRST FOUR-SESSION UNIT
Why does a paper helicopter fall slowly?
Starting with a spinning paper helicopter, children learn to ask testable questions, change one condition at a time, and use observations to explain evidence.
- Ages
- 7–9
- Format
- 4 sessions · Project-based
- Outcome
- Experiment project
ASK · TEST · EXPLAINNOT JUST THE ANSWER
What will children take with them?
Design a fair test
Know when to change only one condition.
Explain with evidence
Compare observations and communicate a clear judgment.
ONE QUESTION · FOUR STEPS
One question, four deeper steps
Every session leaves visible progress and opens a new question for the next attempt.
Make paper fly
Build a first paper helicopter and observe how it spins and falls.
Change one thing
Vary wing length, weight, or height to design a fair test.
Let evidence speak
Record time and behavior, then compare each design.
Share my explanation
Improve the model and explain why it falls more slowly.
MAKE
SOMETHING
REAL.

THE FINAL PROJECT
A tested and improved paper helicopter
Children take home their helicopter, a simple experiment record, and an evidence-based explanation.
Materials we’ll use
Paper, paper clips, safety scissors, ruler, timer, observation cards
