After the first bell rang, everyone was stragling into first period physics class, with Mr. Manning in room 019. Tired and already bored and wanting to just be home, the manheim township students were delighted to see that Elizabeth Conway, high school senior, had brought in doughnuts and juice boxes for everyone to enjoy. Elizabeth says, "I felt like everyone else was bringing stuff in for the class, so i felt i should too." So as the class was enjoying their vanilla iceing doughnuts and orange juice boxes, they were writing down the answer to question two on the home work ( page 12 ) they had done the previous night. So everyone of the students, while still eating their dounuts, were concentrating on the question they were to write down and hand in for points. The home work question has to do with average velocity and average speed. the question goes as follows:

2. Romeo threw a rock up to land on Juliet's balcony. The rock flew (almost) straight up 10 m high and fell onto the balcony which was at the height of 7 m. The whole flight took about 2.20 s. a. What was the rocks average speed and average velocity in this situation? b. Would the rock's speed have been constant during the whole flight at the value you you calculated in part (a)? Explain. So as all the students were finishing up, Mr. Manning was gettin ready for a small activity he was going to share with the class. This activity involved a student walking at a constant speed for five seconds, from the 2 m mark to the .5 m mark. So Mr. Manning asked for a voulenteer and Cory Miller, high school senior, so willingly voulenteered. So he went to the front of the room at the 2 m mark and walked at a constant speed to the .5 m mark. It is a little difficult to keep a constant speed so it took Cory a couple trials to get it right. While he walked, a sensor sensed his motion and graghed his speed for the students on the computer.

After this activity, the students split into pairs and worked on the lab tops. Mr. Manning gave them instructions of how to get to a link to this video another student hade made. The video was with the kid throwing a basketball up and down a few times. So the student were then given a set of directions in order to get the path of the ball graphed. After this was accomplished, the students were to record the Time (s) and the Velocity (m/s) of each point on the graph. At this point however, the bell rang and all of the students saved what they were doing and thanked Elizabeth one last time for the doughnut she had brought in for them. All the students left and and were a little closer to their day off the next day.
