ES Dimensional Analysis problems set 1 and 2

Do the first 5 problems on the D.A. worksheet.  be sure to show all work including units and conversion factors 9 fractions with the units and equivilant values.)  Do second set by 11/4 - 5/12013

Use the conversion factors on your woeksheet.
 




1)  10 Km =  ? miles
2)  the Moon is 250,000 miles from earth  How Many Km is this?
  i.e. 250,000 miles = ? Km
3) 10,000 gal.= ? Cubic meters
4)  Average student is in class 330 min/day.  A.  How many hours /day ?  B.  How many seconds?
5) 1 yr. = ? Sec.

6)  1.3 * 10E15 gals. = ? Liters

7)  355mLper can.  A. ? drops  is this?       B.  How many Cubic meters?

8)  Chicago use 1.2 * 10E9 gallons/day, how many gal./second is this?

9)  60 Miles per hour = ? feet/sec

       10)  1.3 * 10E15 gals in Lake Michigan.  Chicago use 1.2 * 10E9 gallons/day,  if Lake Michigan was never refilled, how many days wouldthe water last?

ES: Volume of a Drop Final


 

Instructions:  DO NOT WRITE ON THIS HAND OUT!  You and your tablemates will be practicing the steps of the scientific method, conducting an experiment and writing-up a lab. 

·       On a separate sheet of paper write the names of the members of your table that actively help with all parts of the mini-lab; this will be your lab write-up.

·       Write out the question I gave you below, include the label Question:

·       Write our Hypothesis: and then your educated guess to answer the question.  Remember to discuss with your tablemates about how to make an educated guess then record the hypothesis on your lab write-up.

·       Continue writing the label for each step (Q, H, T, M, P, D, A, & C) and following my hints for each step.

 

Question:  How much space (volume) does a drop of water take up?

Hypothesis:  What is your educated guess to answer the question? Compare 1 drop to 1 mL of water.

Materials:  Every item used for data collection

Procedures: Step by step directions of your experiment that include diagrams that help illustrate your procedures

Data table:  Have room to include ten trials, Yes, do the experiment ten times, make sure everyone in your group has an opportunity to collect data by doing the experiment.

Analysis:    Show an example of how calculated the volume of a drop, in mL. Also show an example of how calculated the average volume of a drop, in mL, for the trials you did. Create a data table and Bar graph showing the average drop # for all other groups in the class.

Conclusion:         Restate your hypothesis. Did you answer the question?
                    How do your results compare to the other tables?  Explain.
How might error have occurred in your experiment?  What affect might it have had?  How can you redo your experiment to attain more accurate
results?
           

Bonus Points:  if you finish both mini-labs early, you may earn bonus points for applying your data from this lab to the drops on a penny lab to find the ave. volume of the bubble of water that formed on the penny.  Explain what you did and show the calculation.
