20:46:38 Query Introduction to General Themes; Examples (no summary needed) What were some of the things in this introduction that you found interesting or surprising?
......!!!!!!!!...................................
RESPONSE --> I found it interesting how many questions that mathmatics can really answer and in everyday life how it could be used confidence assessment: 2

20:48:43 Query Introductory Flow Experiment (no summary needed) Is the depth changing at a regular rate, at a faster and faster rate, or at a slower and slower rate? Support your conclusion.
......!!!!!!!!...................................
RESPONSE --> The depth is occurring at a slower and slower rate because as more time passes the pressure in the bottle becomes less and less therefore the bottle would drain slower and the data also showed to support my conclusion confidence assessment: 3

20:49:08 ** If you time the water at equal time intervals you should find that the depth changes by less and less with each new interval. If you timed the depth at equal intervals of depth you should find that each interval takes longer than the one before it. } Either way you would conclude that water flows from the hole at a decreasing rate. The reason is that as the water depth decreases the pressure forcing the water out of the hole decreases. **

20:51:37 What does the graph of depth vs. clock time look like? Is it increasing or decreasing? Does the rate of increase or decrease speed up or slow down? Does your graph intercept the y axis? Does it intercept the x axis? How would you describe its overall shape?
......!!!!!!!!...................................
RESPONSE --> as time increases depth decreases at a slower rate. The graph is decreasing. My graph didnt cross either however it would have crossed both eventually, It has a negative slope and is linear confidence assessment: 3

20:52:16 ** The graph will start on the positive y axis and will decrease at a decreasing rate. The shape of the graph is the left-hand side of a parabola that opens upward. The right-hand half of the parabola does not correspond to the flow. The lef-hand half of the parabola, which corresponds to the flow, gets less and less steep with increasing clock time, matching the fact that that the rate of decrease is slowing. At the instant the containers empties, the water will be at the level of the hole. If depth is measured relative to the hole, then at the instant depth will reach zero. The corresponding graph point will lie on the t axis and will correspond to the vertex of the parabola. **
