Ask HN: Any good science/hypothesis type projects with Arduino?

Trying to come up with cool Arduino projects for my 12-yr old that answer some scientific question vs just build something. Thanks.

I doubt you could plan to answer any outstanding (as yet unanswered) scientific question.
Perhaps looking at Newton, Faraday, Volta, etc era questions and answer them using novel means. Those guys in history didn't have the benefit of Arduinos and the enormous collection of sensors, etc.
Some examples:
```
    \* Measure speed of sound using either speaker, microphone or ultrasonic devices.

    \* Measure gravitational acceleration by dropping a weight from different heights.

    \* Investigate the relationship between current, coil-turns and magnetic force.

    \* Measure temperature, humidity, barometric pressure to track / predict weather.

    \* Use ArduCam to take time-lapse photos of seedlings, etc?
```

  Oh cool! Thanks so much. (Btw, I didn't mean to suggest that the project should address an unanswered question. Ok to repeat known experiment if it's fun/insightful).
  The gravitational acceleration one is cool. I remember doing this in high school back in the 90s. Let me suggest that to him. Thanks again.
