...like a pendulum bob in the air, back and forth, back and forth. Is is the mass of the bob? Is it the length of the string? We are left to wonder...
But for now, no homework, except to write up your lab very simply, one sentence descriptions:
Purpose: To build a one-second pendulum
Question: What makes the period of the pendulum move faster or slower?
Hypothesis:
Data Table:
Conclusion: Does the data support or disprove your hypothesis?
Now what is your new hypothesis?
This was a great experiment for showing the value of controls- those things that stay the same, and the single variable which you change. Even though we have not finished...
And I'll See You On Wednesday afternoon, at the Exploratorium!!! ...where we will spend some quality time...with More Pendulums!!! You may bring your pocket-size cameras; it is a great way to take pictures AND notes! Also, I will give tickets for Store! Maybe a treasure hunt!
Wow!
YAY!
