Walking into class, there were no papers to pick up. I was so sure there was going to be a pop quiz for it is very odd to not have any worksheets. No, Mr. Manning assured us, there was no test. We were going to work on a paper we picked yesterday (okay, now everything makes sense).

On the board: Make-up work Test/RG reminder Lav pass reminder predictions simulations discussion

Make-up work (anything before the Wooly Mammoth lab) is due by the end of the day. When you goto the Lav, don't forget to take the whole clipboard, it serves as the pass. On monday there is a test, but it won't take all period. For the rest of that period we will will be doing Demos. By then it is important to have your reading guide done as usual.

For the rest of the period we worked on page 16--Make predictions, test predictions. Important--measure where it hits the ground, don't worry about any rolling. And 90 degrees=straight up into the air.

Our predictions: 1. 45 degrees 2. parabola 3. no 4. 90 degrees 5. 45 degrees 6. same time 7. a. shorter and wider parabola b. take longer Put EVIDENCE to observations We then got out some computers and got into groups of 2 to find out if our predictions were correct. You can try this at home, if you missed it during class. Just goto this website-- http://www.sciencejoywagon.com/explrsci/media/range.htm (but remember to be in FIREFOX not Safari). You will be playing with an artificial golf course to learn more about projectiles. Have fun!!
