Measure the value to the nearest hundredth of a centimeter and record the value in Table 1. Use the chart to help you answer the questions. The feather will be the slowest to hit the ground, because its shape is spread out more than the steel balls air travels easier through it. M: Oh, ok, so what does this slope mean then looking at the C vs. My email is in the details asked when I posted this comment Thanks.
How can something as simple as measuring circles turn into this ridiculously long post? After collecting the data, we calculated it to meters from centimeters. It simply represents the situation in a mathematical form. Prediction: I measured the diameter of a glass cup. You will be helping Galileo perform the experiment to determine if objects with different mass fall at the same, or different, rates in the air and in a vacuum. What is the dependent variable? You must provide two ways that they are alike and two ways that they are different. This takes about 30 minutes. You may make a list, write in paragraph form, or make a chart.
. Record the value in Table 1. I took time the next day to do a summary of how models were used in this lab. S: No, just a bit more. Carefully measure the diameter of the circular surface of each object. We then compared all groups graphs to each other.
However in a vacuum since there is no air in a vacumm, there is no air resistance. The usual things were brought up: radius, diameter, circumference, area, and maybe something else. Group: Alana, Joey, and Aidan 1. Our data was fairly close to the other groups. For the smaller objects, we used the area as if they were square i. C graph S: Inverse of pi M: What does that mean? Record the results from step one of the experiment dropping the objects in the air : First trial: Droping the steel ball and the feather The steel ball hit the ground before the feather.
Third trial: Droping the cannonball and the feather The Cannon ball hit the ground before the feather. Just like the circumference, we did not include the y-intercept because it was insignificant and did not pass the 5% rule. Since this method of measurement tends to increase error, measure to the nearest tenth of a centimeter. The headings that have been used in most previous activities are as follows: Title, Purpose, Introduction, Materials, Procedure, Data, and Questions. The forces acting on objects dropped in the air are: shape and air resistance. I will use the Circle Lab to model proper techniques for sharing information.
Compare and contrast these forces. This box also shows the slope value. Hint: Your answers from question 1 should help you make the proper selection. Then they realized that the graphs that were done the same all had slopes that were very close to each other. From there it is time to graph. Scroll down till you see the man standing on the tower.
Area was calculated by multiplying 0. Based on all of this discussion we are now able to write and mathematical model for circles. Strong and Weak Nuclear Forces are alike because They both are short range Forces. Our mathematical for circumference vs. We recorded our data in meters.
Since I introduced this lab as and exercise in measuring I next ask the students what could we measure about the circle. This difference could be caused by improper measurements, or simply because other groups had wider or narrower ranges of data and the different units of measurements. More on Unit 0 later. Did the experiment support your hypothesis? One thing I did not mention was whether to measure in inches or centimeters. Having them create a simple linear graph from actual data is always a good thing.
