Study for EM test

Even classes test Tuesday & Odd classes test Wednesday.

All notebooks considered approved if the notes are in your own handwriting & no loose papers in notebook.

I have advised making the final draft of the Density of Mineral lab as a homeowrk assignment versus completing it (question #4) during the test, see earlier post.

Density of Mineral accepted values and FD info for EM test question

Students have conducted data collection for the lab in class and they have been told they may complete the final draft at home (recommended) or they may do the FD in class during the EM Test (four questions timed at 60 minutes total).

Lab Final Draft requirements (EM test question # 4)

Data Table:  make a ruled data table to record your measurements and observations.


Analysis:

1. Show your calculations for the density of each mineral sample
2. Make a bar graph that compares your calculated density for each mineral sample to the accepted density of the mineral samples provided by your teacher.  Graph the mineral samples from least dense to most dense.
3. Make a diagram that shows the crust, mantle, outer core and inner core of the Earth and label where the minerals identifed in your lab would be found based on Density alone.

Conclusion:  The following are prompts to help you write a conclusion.  Write you conclusion using complete sentences and the rubric.

Frame work: Were you able to identify the unknown minerals by calculating their density?  If not, how did you identify the samples?  Evidence: Compare the accuracy of your density calculations to the accepted densities, USE NUMERIC EVIDENCE.  Logic:  How does your measured mineral densities compare to the class average and the actual densities?  Error:  How did error influence your calculated densities? Mention more then one source of error and its impact on data Next Step:  What could be done to improve/further investigate this experiment and why might this lab be useful to society at large?

Accepted DensityValues (mineral name, density and other properties)

Sulfur 1.96g/cm³    opaque, yellow color smells of rotten eggs

Calcite 2.7g/cm3 colorless, monoclinic crystal clear translucent – yellow-whitish opaque Calcium Carbonate

Granite 2.5-2.89 g/cm³  composite rock with smaller crystals black, grey, white and possible green or pink;  mostly silicate dioxides

Hematite  5.26g/cm³   black – reddish color, may have rust mostly iron oxides

Pyrite   5.1g/cm³ metallic yellow maybe shiny can have cubic crystals iron sulfide compounds

Galena 7.5 g/cm³  shiny metallic silver cubic crystals may have yellow sulfur or black material attached a lead sulfide

Milky quartz ~2.6 g/cm³  clear –white-rosy color, looks like rock sugar

Magnetite   5.2 g/cm³  Black/sparkles-metallic/shiny magnetic (will influence a compass needle)   iron oxides

Garnet 3.4-3.7 g/cm³  red-brown-tawny-white, glassy with conchoidal fracture

Olivine  3.3 g/cm³     green with cubic crystals a silicate

Average density by interior layer

Continental Crust:    2.7 to 3.0

Oceanic Crust:        3.0 to 3.3

Mantle (silicates):   3.3 to 5.7 (increasing with depth?)

Outer Core (liquid):  9.9 to 12.2

Inner Core (solid):  12.6 to 13.0

EMP log 6, EMP poster and individual log entries

EVEN classes EMP poster, EMP individual work log and illustration WCP(s) due at start of class 2/2/11 as a hard deadline.  Earth Moon test next Tuesday 2/8/2011, consider all notebooks approved for this test if you do not have photocopies of notes and all loose papers are pasted into the notebook.

ODD classes EMP poster, EMP individual work log and illustration WCP(s) due at start of class 2/3/11 as a hard deadline.  Earth Moon test next Tuesday 2/9/2011, consider all notebooks approved for this test if you do not have photocopies of notes and all loose papers are pasted into the notebook.

Final EMP log entry (#6):
1)  What did each member of your group do towards completion of the poster today?  2)  Did (or Does) your group need to meet outside of class?  Explain.

EMP log 5, EMP Poster work and EM test date

EVEN day classes; logs will be due with the poster on Wednesday 2/2/2011
ODD day classes; logs will be due with the poster on Thursday 2/3/2011

Log entry #5
-What quadrants still need work?
-How will your group address computer generated tables/charts/graphs/titles?
-How will your group complete the WCP?  one/group = A -OR- one/person = B
-If your group is behind at meeting daily work goals (you will only have ~30 minutes next class); when and where will your group meet to complete the poster.
-What did each member of your group do towards completion of the poster today?

If your group was not meeting daily production goals you will need to meet outside of class to complete the poster.  This is a cooperative group project so you should make every effort to meet as a group to work on the poster outside of class.   My after school office hours on Tueday 2/1/2011 would be an ideal meeting place for groups.

The Earth Moon System test will be early during the second week of February.  Students do not need to have notebooks approved for this test; I will explain more as the test date approaches.

Earth resources 2 & EMP log 4

EVEN Classes DUE 1/27/11
ODD classese DUE 1/28/11

Based on earlier hw readings:  1) What are fossil fuels? and give three examples.  2)  What are alternative energy resources?  describe three.

EMP log 4: 
If you have met daily goals your poster should be ~ half way illustrated for all quadrants on the Earth and Moon.  1)  How do you feel about your group's research towards goals in poster production?  What did each member of your group do towards completion of the poster today?

EMP POSTER DUE DATE

After 1/24/2011 Students have been given 150 of the 300 minutes of in class poster production time.  If students have met daily work goals they should have scale drawings of the earth & moon quartered, scaled interior layers sketched for the matter & interior quadrants and some EQ content sketched into the surface & interaction quadrants.

The poster and illustration WCP will be due in class as a hard deadline on:
EVEN classes 2/2/2011
ODD classes 2/3/2011

Earth resources 1 and EMP log 3

Even day classes due on 1/25/2011

read pages 655-658 & desciribe the difference between renewable and non-renewable resources; give three examples of each.

EMP log 3
1)  How do you feel about your group's plans to illustrate all EQs for all quadrants
2)  What did each member of your group do towards completion of the poster?
