Body Response Group Lab

For this lab, you will be planning, carrying out, and writing up a simple body response lab with your table group.  These are the requirements:

  1. Pick a vital sign you want to measure (heart rate, blood pressure, tidal volume, or respiration rate), the tool(s) you will measure it with and the activities you will have your subjects do.  You are required to measure your subjects at rest, after mild exercise, and after more vigorous exercise.
  2. Carefully and consistently take data with as many subjects as you can.  I recommend starting with yourselves so you can iron out any challenges, and then measure at least one more group.  
  3. Lab Write Up:  As a group, you need to write a lab with the following components:  1)  Focused question   2)  Variables (especially discussing controls!)  3)  Procedure/Methodology   4)  Neat organized data table with uncertainty, units, etc    5)  Data Processing:  Could be as simple as calculating percent changes and showing a sample calculation, but you could do more than that too    6)  Conclusion:  Refer back to question, use specific data to back yourself up, explain using science, discuss the impact of uncertainty on the data.
  4. Due Thursday/Friday before break.  You can finish it in class after you take the test.

Populations Lab

Some students have asked for the Populations L  ab requirements spelled out more clearly.  So here it is!


  1. Focused Question:  Clearly states what is being tested in the investigation.  It is possible in this lab that you might have a secondary question,  and that is ok with me this time!
  2. Background Information: 1-2 paragraphs of background of the investigation.  This can include your personal experience, research (cite the sources!), and educated guesses.  Generally a good background goes from more general information to the most specific and addresses your actual question.
  3. Variables:  Here you list the dependent variable, independent variables, and the controlled variables.  You need to discuss how you controlled (or monitored) the controlled variables, barriers to controlling them, etc.  If you are doing a strict correlational study, then technically there is not a dependent and independent variable and you can say that.  However, if you are doing a t-test, then you can state that whatever varies between the 2 populations is the independent variable and what you are comparing is the dependent.
  4. Procedure/Methodology:  This can be in a list format or paragraph, but either way, it needs to be detailed enough that another investigator could accurately reproduce your procedure.  Make sure that you include details about how you measured things, how many trials, etc.
  5. Data Table:  Should be neat and organized.  Needs to have clear labels (a title can help!), units, uncertainty, and needs to have quantitative as well as qualitative data.  The qualitative data (observations) are often written under the quantitative table or can be included in the table.
  6. Data Processing:  This can include calculations, graphs, or other visuals.  Calculations should show the complete work for at least one sample of each type of calculation done.  Graphs should be well-titled, have uncertainty bars (where appropriate), have good labels, units, annotation, etc.
  7. Conclusion:  Refer back to your question and answer it using data to back yourself up!  When doing a t-test, it is important that you reference the averages of each group as well as the t-value result.  Use science to try to explain your results.  Discuss the impact of uncertainty on your results.  
  8. Evaluation:  Discuss strengths and weaknesses of your investigation.  I would encourage you to list 3 strengths.  For the 3 weaknesses, you can list them in a table as we have done before.  Describe the weaknesses, you can list cause of the uncertainty/limitation and suggest possible realistic improvements for each of them.  Also, list further investigations that you could do next and why you would do them.

Lesson Plan for 11/4 and 11/5/2019


  1. No Early Work!  We will start a new sheet and add up the old set on Wed/Thurs.
  2. Dichotomous Key of Fish Assignments.  Mr. Plies will give you some tips and go over how to do the first fish.  You can do this assignment in pairs and then turn in 1 fish sheet with both of your names on it.  You can give the Fish Key sheet back to Mr. Plies when you are done so we can reuse them.
  3. Now you can design your own dichotomous key to separate at least 10 items from the theme of your choice.  Some ideas include movies, fruits, sports, etc.  There are many ways to do it, but you should include at least 10 images and write your key based on observable characteristics.
  4. When done, work on your pre-write for your Populations Lab.  We will start taking data on Wednesday.  First draft is due next week, so make sure you have plans to take your data.  
  5. 4th Period:  You can also work on completing the Animal Phyla Lab.

C2 Work

You'll notice that C2 has many concepts in common with 4.2, but it goes into more depth.  As you read through the section, answer/do the following in your notebook.


  1. How can an owl pellet be used to determine information about the owl's community?
  2. Use the information in the sidebar on p. 615 to construct a food web.
  3. Do the DBQ on p. 616.
  4. Explain how food conversion ratios can be used to eat more sustainably.  Use numbers to back yourself up.
  5. Examine the Whittaker climograph on p. 617 and describe what it shows.
  6. Examine the net primary productivity listings on p. 618 and propose why some are very high and some are very low.  Use specific examples.
  7. Do Question #2 in the Activity listed on p. 618 (draw 2 energy pyramids, compare, and explain).
  8. Examine the Gersmehl nutrient cycle diagrams on p. 619 and do the Activity questions related to it on p 620.
  9. Do the George Vancouver DBQ on p 621!
  10. Read about respiration rates and biomass accumulation and do the question on p. 622.
  11. Do the secondary succession question on p. 623.
  12. Describe how humans can interfere with nutrient cycling.

Mesocosm Assignment

One of the 7 required practicals for IB Biology is to study a mesocosm in the classroom.  

The write-up will be due in 2-3 weeks (will be finalized after I see how the mesocosms are doing) through turnitin.com and should include:

  1. Detailed observations from at least 6 separate days.  Include water clarity, condition and growth of plants, types of animals, behavior of animals, condition of muck and other debris, etc. Make it clear which mesocosm goes with each observation and which day.  You can include details about the classroom conditions (temperature, light, etc) if you think they are relevant.
  2. Use vocabulary from the ecology unit to try to explain what you think is happening in the mesocosms.  For example, information about cycles, energy, and types of nutrition would be appropriate.  You don't have to know exactly what is going on or know the names of the organisms, but do your best to give reasonable explanations.  If you use outside information in your explanations, state where or how you got the information.
  3. Predict what you think will happen in the mesocosms, giving a reason for your predictions.

Overview of DNA Fingerprinting Lab: to be done on Monday, Wednesday, and Friday of next week

Day 1: (Monday, April 22).  Label 4 microfuge tubes.  Add 5 microliters of one of the DNA samples (crime scene, suspect 1, suspect 2, suspect 3).  Add 5 microliters of restriction enzyme (EcoR1) into each of the tubes.  Restriction Enzyme must be kept on ice!  Put your tubes in your styrofoam "floatie" and put in the water bath for an hour!  After an hour, remove your labeled tubes and put them in the designated rack, which will be refrigerated until Wednesday.

Day 2 (Wed, April 24):  Take your samples from Monday and warm them up in your hands.  Add 2 microliters of dye to each of the 4 samples and spin in the centrifuge.  Carefully load 10 microliters of each of the 4 samples into a gel.  Make sure that you make a key so that you know which sample is where.  After both groups have loaded their samples into the gel, one group needs to load the "ladder" in one of the leftover lanes in the middle.  The gels will be hooked up to the power source and turned on.  You can watch bubbles form and then watch the blue dye migrate across the gel.  You should label the baggy that your gel was in with your groups' names and then put it near your gel.  This will ensure that I will put your gel in your labeled baggy after the gels are done running (because they will be done after you leave).

Day 3 (Fri, April 26).  You will get the baggy with your gel.  Go into the microscope room with your gel and put it in the "illuminator".  Turn the lights off, turn the illuminator on, and view your gel!  Have a few different people take photos of the gel.  When you leave the room, determine which photo works best and share it with your group numbers.  You can also send it to me!

Write up details to follow.

Boston Children's Hospital Virtual Stem Cell Laboratory

This activity can be done in pairs.  Go to the Boston Children's Hospital Virtual Stem Cell site and do the following.  Answer on a separate sheet of paper and turn in during class on Friday 4/12 or Tuesday 4/16.
  1. Go to the Boston Children's Hospital Virtual Stem Cell Laboratory (linked on my website)
  2. Read the Introduction and about Embryonic Stem Cells
  3. Start the simulation by choosing a coaxing agent (one of the 5 colors).  If that coaxing agent works in the ES cells, you will see movement along a pathway.  If not, try a different coaxing agent until you get some movement.
  4. Write down the coaxing agent that you chose and what new cell type you went to.  Read about that cell type.
  5. Continue with the coaxing agents until you reach the end of a pathway.  Write down the ending stem cell and what it can be used to treat.
  6. Start over with a whole new pathway (or just back up one step to get to another), writing down the coaxing agents and products as you did above.
  7. Repeat this process for 5 different complete pathways.
  8. Summarize what you learned about embryonic development and how these early cells can be used to treat different disorders.
  9. If time:  Discuss the ethical pros and cons of using embryonic stem cells for treating patients and write down 2 pros and 2 cons.

Genetics Test Update

Due to the Snow Day on Wed 2/27, the Genetics Test has been moved to Fri 3/1.  Prepare yourself by learning about 2 single gene genetic disorders, review how to set up a dihybrid Punnett Grid and complete it, review how to do a chi-squared test, calculating expected values, plugging into the equation, and interpreting the results.  Much of this information is in 10.2 and can also be found in the Genetics Notes on-line.  We will start Sections 2.6 and 2.7 right away after the test because we will have to cover the next unit before Spring Break!

Information about the Genetics Test and Assignments for Monday 2/25

On Monday 2/25, we will be reviewing for the Genetics Test (including Kahoot!), checking off some assignments, and going over the genetics problems.  This is what I will check off:
  1.  DBQ's from pp. 452-454.  On pp. 452-453, pretty much ignore the directions and do 2 things with the 2 sets of data that you get.  1)  Calculate the recombinant frequencies using the smaller numbers for recombinants and 2) Calculate the expected results if these genes were not linked.  For the DBQ on p 454, you can do it as instructed.  The contingency table is basically a chart showing the observed and expected numbers for all 4 phenotypes.
  2. For the Card Lab:  1)  Your observed results for all 3 phenotypes  2)  Your expected results for the 3 phenotypes, showing work   3)  the Chi-squared calculation, showing work    4)  the critical value (see chart on p. 454)  and 5)  Your interpretation of the result
This is what will be on the Genetics Test on Wednesday 2/27.  There is a bit more on the Review Sheet in the documents section of this blog:

For the Test, Know how to:

  1. Draw Punnett Grids to predict genotypes and phenotypes of monohybrid and dihybrid crosses
  2. Apply Laws of Probability to predict genotypes and phenotypes of crosses
  3. Analyze a Pedigree to determine genotypes of a family and to determine whether a family trait is dominant, recessive, autosomal, or X-linked
  4. Do problems involving the ABO blood groups in humans
  5. Make predictions involving sex-linked traits
  6. Calculate chi-squared results and determine whether hypothesis should be accepted (you will be given equation and chart for determining significance)
  7. Identify which of the offspring are recombinants in a dihybrid cross involving linked genes and calculate recombinant frequencies
  8. Explain the genetic causes, symptoms, and potential treatments and interesting facts for 2 single-gene disorders.  Some examples include sickle cell anemia, Huntington’s disorder, cystic fibrosis, maple syrup urine disease, galactosemia, phenylketonuria (PKU), and many more!
