Biology 9/19 HW/RD

Here is the guide sheet for the Measurement lab.

Measurement Lab

Title:  Hint, be descriptive and to the point

Question:  How can OHS measuring devices be used by students to accurately measure the density of water?

Hypothesis:  Hint, your answer must include the independent and dependent variables you will test to support or refute your question.

Test:  Hint:  Density = Mass/Volume.

Materials:
(1) P-1000 micropipette, (3) Reaction tubes, box of blue tips, (1) 1000mL plastic waste beaker, (1) metric balance, supply of dH20 in (1) small glass beaker, paper towels, safety equipment-eyewear and aprons…….

Procedures:  Hints, Make sure your final procedures include labeled diagrams
  1. for the Rd just do your best to describe how to use each material in a logical order  
  2. for a diagram show how the P-1000 window will read for each different volume extraction and how you will use the balance.
  3. you will conduct at least of 3 trials of data collection for each member of your group
  4. you will need to empty rxn tubes of any trace of water and re use-them,

Data Table: 
(example:  Remember that you need room for at least 9 trials!!)


Measurer
Mass of empty tube
Mass of tube and H2O
Mass of H2O
Volume of H2O
Calculated H2O density







DON’T forget to record observations of data collection

Analysis: 

This section should include a graph of the data (mass on the y-axis & volume on the x-axis), the formula for density, show at least one example of the math you did when calculating density and answer the following questions. Hint you will want to convert measured μL – mL to answer the questions
  1. Check your accuracy for the measurement lab; calculate percent error for the average of your three trials?  

Percent error = (measured average density – 1g/ml)  . 100%
                1g/ml

  1. What is the accuracy for the average of all trials by your group?
  2. Which measuring device is most accurate?  Explain your answer
4. E.C.  graph volume  -vs- mass For water for all 9 trials. 
Conclusion:(This should be at least 3 paragraphs)

Don’t forget to explain what happened?  Restate your question and hypothesis and why you thought it was the best guess.  What do you know about the answer to the question?  How does the data support your answers? i.e.use numeric comparisons to support your answers!  How did human error influence your data?  How could you further/redo this experiment for more accurate results?  What is the social context for this lab?

ES HW 9/16/2011

1)  Final FOP Journal:  How well did you work today?  How about your group mates?  Any problems that occurred?  How well will your group  meet the Friday  2:45 pm deadline for the map?  Any concerns or comments?

2)  Write detailed directions from your house to the school.  Draw a map showing key features, like street names, , to accompany your directions.  (Discovcery Lab on pg 27)

3)  Read and take notes for section 2.1 in the Glencoe Earth Science book, pgs. 26-31, into  your notebook.

Biology Hw 4th period

1)  Complete micropipet worksheet- needs to be 100% correct to get into lab.

Biology Hw 2 period

1)  Complete micropipet worksheet- needs to be 100% correct to get into lab.

2)  Complete the write for big mouth lab into notebook!  include a graph of people vs. mouth volume in ml.  Finish analysis and conclusion as shown on standard lab rubric handout.

Purpose:  You are to figure out who has the biggest mouth in class.

Question :Who has the larger oral cavity?

Hypothesis:  (You give)

Test: We will fill the mouths of volunteers with water to get an approximate volume of their oral cavity.  We will do this multiple times and take an average so that we can compare class data.  We will also measure the height of all participants, in meters.

Materials/table
·       2 cups *Note NO LIQUID, CONTAMINATED WITH SALIVA, MAY GO INTO THE GRADUATED CYLINDERS!
·       100 ml Graduated cylinder
·       Pen or pencil
·       marker
