BIG “OH, I GET IT.”
Change one thing.
Notice what happens.
Make a prediction.
Put it to the test.
Find the pattern.
Explain it in your words.
THREE WAYS IN
Start with a question.
Three featured experiments to start with.
Open a simulation and explore. Suggested ages 11–16.
Why does a cylinder
become a rectangle?
Unroll the side. Change the radius. Discover where 2πrh comes from.
One bulb out.
What happens next?
Build a prediction, then compare series and parallel circuits.
Where does the
energy go?
Release a ball. Follow potential and kinetic energy, then add friction.
EARLY CLASSROOM PREVIEW
A STARTING POINT FOR YOUR NEXT LESSON
Less explaining.
More discovering.
A visual experiment is the beginning of the conversation. Each activity gives you a question, a simple investigation, and a way to check understanding.

- 01
Predict before you press play.
A focused opening question gives every student a way in.
- 02
Change it. Watch it. Compare.
Students test one variable at a time and record what they notice.
- 03
Explain the “why”.
A short exit question turns a visual moment into an idea they can use.
ONE QUESTION. A NEW DISCOVERY.
Learning notes. Ideas you can test.
Explanations, worked examples and investigations linked to real experiments.
