2-6

On Friday we had another great time in Mr. Manning's third period class!
 * __TPJ for Febuary 6, 2009 __**

We started the period by reading page 14 (the lab we got on Thursday). After we read it, everyone made predictions. What did everyone else predict? A) 8 people B) 2 people C) 10 people

After we read and made predictions, Mr. Manning told us some things to know for the lab:
 * Use the small tube for the small height
 * Use the longer tube for medium height
 * Then use both together for the high height. Make sure the seem where they connect is as closed as possible so the driver doesn't hit it when you drop it down.

Then we watched a short video on the way to use a calibor, which is the instrument we used for measuring the height of the nail after each hit. Ask Mr. Manning about this and he'll show you how to do it.

Finally, we began the lab!

The lab procedure:

1. First, measure the scale of the driver. 2. Tap nail in the wood very slightly just so it cand stand up on the block of wood. 3. Measure the height of the nail using the calibor. 4. Measure the height of the tube using a meter stick, lable this number as "Height of driver" on the lab 5. Set up cylinder on top of the nail on teh block of wood so that the hole in the driver strikes the nail


 * repeat steps 3 through 5 for each height, make sure you do two trials for each height

Step #2:



Setup to drop the drill:



And that concludes what we did on Friday!
