Today's Objectives: Daily Question, TPJ Examples/Schedule, Galileo, Demos, 1st Law, JSM, and HW

When first walking into class, there was a worksheet on the front desk and the worksheet was called Newton's 1st Law. After picking up the worksheet, we then answered the daily question.

Daily Question: How would Aristotle explain a falling apple? Answer: Natural Motion

Mr. Manning then passed around the TPJ schedule that showed the dates you will be doing the daily log. After that, he then started teaching us about Galileo. Galileo thought Aristotle could be wrong so he decided to experiment. There were many demos shown in class. The first one that Mr. Manning showed us was Galileo's inclined plane experiment. When the ball was released to the opposite side of the ramp, it was the same measurement as the other ramp. But when the the one ramp was flat, the ball continued moving and fell onto the floor. This was because of inertia. Inertia is when objects resist changes in motion. The other demos included a vase, hoop, and marker. Mr. Manning put the vase on the bottom, the hoop in the middle, and the marker on top of the hoop. He then quickly grabbed the hoop from under the marker and the marker then fell into the vase. Then next demo Mr. Manning did for us included a knife and a banana. He held the banana in the air, and after releasing it, he was then able to cut the banana in half. The final demo that Mr. Manning showed us involved a balloon and a hockey puck. After blowing up the balloon and putting it on top of the hockey puck, he started to push it from side to side. It puck went at a constant speed the entire time. We then split into groups of three to try another experiment. We grabbed the weights from the closet and put them on top of a piece of paper. We then pulled the paper downwards and the weight did not move.

After demonstrating the experiments, it was then time for Mr. Manning to go over the 1st law worksheet. After explaining the definition which is on the front of the worksheet, Mr. Manning then told us that we were going to watch a movie. It was a movie with Professor Julius Sumner Miller on the subject of inertia. The movie showed some of the same experiments we saw in class but it also showed new ones. We were to then fill out the questions on the back of the 1st law worksheet. If we did not finish it in class, it was assigned for homework.
