18:07:14 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 --> Some of the things that I had forgotten. The formulas and how to go about them. How everything is done step by step and how you have to go through it that way to better inderstand it. confidence assessment: 3

18:07:47 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 changing at a slower and slower rate. confidence assessment: 2

18:08:21 ** 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. **
......!!!!!!!!...................................
RESPONSE --> As you water the water you can see that it is decreasing until it finishes. self critique assessment: 2

18:09:31 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 --> The graph is a curved graph. It is decreaing. It decreases and slows down. No. No. It is a curved shape. confidence assessment: 2

18:13:10 ** 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. **
......!!!!!!!!...................................
RESPONSE --> As the water starts to flow to will decrease at a decreasing rate. As the graph goes on it will get less steep as time goes on. This indicates that it is decreasing at a slower speed. self critique assessment: 2

18:15:25 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 --> The formula that was used I had forgotten but after I worked with it I understod it better and how to use. After working with it, it was easier to do and I realized how to work the problems in order to get the answers. confidence assessment: 3

......!!!!!!!!...................................
RESPONSE --> As the water flows the time keeps decreasing until all the water is gone. The water flows at a decreasing rate. Everything decreases and it makes to water go out of the hole. self critique assessment: 3

RESPONSE --> The graph decreases. The graph gets steeper and steeper as time goes along. This makes the rate decrease at a slower speed. self critique assessment: 2
