Engineering and Design.
🎯 Your mission
Play with the model. Break it. Understand it.
⚡ The twist
The first design always fails. That's the point.
Mind = Blown
🚀 The Saturn V rocket burned 20 tons of fuel per second at liftoff.
Make a hypothesis first
Guess: what's the weakest part of this build?
What You'll Learn
Sound waves have properties including amplitude (loudness), frequency (pitch), and wavelength. Higher frequency means higher pitch. Greater amplitude means louder sound.
Key Words
- prototype
- design
Steps
Study the diagram and label the parts you recognize.
Build a working anemometer using paper cups and straws. Calibrate it by counting rotations in a known wind speed.
Observe what happens and describe it in detail.
Record your observations in your science journal with measurements and descriptions.
