In this Lab the students were required to do several tests and measurements and then convert these units into other units. There were five tests in all. The first test was measuring the average of three broad jumps in centimeters then find out how many jumps it would take to travel one mile. The second test involved measuring a candy bar (for my group we used a snickers bar) then finding out how many snickers bars end to end it would take to wrap around the equator of the earth. For the third measurement we had to find out how many tootsie rolls were equivalent to a five pound tootsie roll. For the next test we had to find how long it took in hours to get to the center of a tootsie pop. For the final test we had to calculate our speed in mph then find out how many days it would take to get from Indianapolis to Chicago if you only walked five hours a day. The materials we used were a gram scale, tootsie roll, tootsie pop, snickers bar, and a meter stick.

Materials
1. gram scale
2. tootsie roll
3. tootsie pop
4. snickers bar
5. Meter stick.
Procedure
1. Broad jump
2. Measure it
3. Repeat two more times
4. Average it
5. Convert to inches
6. Find difference between that and a mile
7. Measure candy bar
8. Divide by the circumference of Earth
9. Measure Tootsie Roll find the amount in pounds subtract difference 10. Eat a tootsie pop
11. Find walking Speed
12. Calculate speed in mph
13. Find time to get from Indianapolis to Chicago

Conclusion
In the dimensional analysis lab several tests were performed and there results were converted into other units. There were five tests performed in all. Each test was different. In one test we measured jump length in centimeters then converted it in order to find out the amount of time to jump one mile. These were all good practice for something we made need in the future

I. INTRODUCTION
Speed, distance, time, and acceleration are all very complex formulas that are interdependent. These formulas are measured in motion data and used to determine the final instantaneous speed, distance, time, and acceleration. Distance and time are two formulas that are used to determine speed and time. For example, distance equals speed multiplied with time given, time equals distance divided by...

1) Once the simulation opens, click on ‘Show Both’ for Velocity and Acceleration at the top of the page. Now click and drag the red ball around the screen. Make 3 observations about the blue and green arrows (also called vectors) as you drag the ball around.
The vectors appear to have both direct and inverse relationships with each other. When I move the ball one direction, both of the vectors...

...Lab Conclusion
When comparing the average speed results from part two of the lab and the definition of acceleration, you find similarities between the two. First, average speed is distance divided by time, and we use it to describe the motion of an object moving at changing speeds. We can see this from our lab results from the average speed of the marble traveling down the ramp, because it picks up speed. When the marble is released at the top of...

...10. Tubes 2, 6, and 7 showed the effect of pH on amylase activity. The results of this experiment indicate that the activity maximum of amylase is at pH 7.0, whereas pH 2.0 and pH 9.0 demonstrated very little activity. In this experiment, pH 7.0 showed the highest level of amylase activity. Tube 3 showed that amylase did not contain maltose contamination. Tubes 3, 4, and 5 showed that water had no starch or maltose contamination. Tube 3 directly showed that water did not have maltose or...

Heart Rate Response to Baroreceptor Feedback Lab
Fundamental Question: Does the body respond to its environment?
Testable Question: When the body is in the squat position to normal while the time limit stays the same and how far you squat is the same, will the heart rate recover after returning to standing position in 10 seconds?
Hypothesis: If the body moves back to normal position from squatting...
