Now on to the next subject. Homework is to make a pendulum, any size you want, and observe, observe, observe. Write down your observations and the questions that come to mind as you ponder. I expect you to
spend 45 minutes and write about 2 pages of notes(legibly) .
A pendulum is simply a weight hanging from a string attached to a fixed point, like the edge of a table, and which is free to swing back and forth.
Write down:
What do you see, and what mystifies you...
What questions, what hypotheses, what possible experiments, what variables and what control...
What use is there, you will probably ask...
What deep truths to be unlocked???
No research in books or net, just hands and eyes, body and brain. You may also use measuring tools, like a tape measure or meter stick, and remember time can be measured too. An ipod or itouch or smarty-pants phone, even a watch with a second hand or stopwatch will work. Experiment=Experience.
Please bring those ipad/itouch/smartphone or stopwatches on Monday to class.
Extra Fun : If you have a little brother and sister, take them to the park, and swing. Especially if they are named Bob. Think about it.

Now reread the directions to make sure you have done all I asked.
