Learning Goals for Rotation
  • Learning GoalsBy the end of this rotation I will be able to:
  • Have an understanding of animal organs and how they work together to form systems
  • identify dis-ease that can develop in organ systems
  • be able to relate stem cells to potent cures for dis-ease and the research that allows for this
  • discuss key ideas surrounding moral, ethical and social issues surrounding stem cell research
  • perform a dissection to identify key organs and their systems


Activity One: Stem Cell

There are several steps to this centre.  The final piece to this centre is a Podcast – record it in the comment section below…


Please watch the following Vimeo channel – https://vimeo.com/channels/sciencerocks/videos.

  1. Watch the RNAi clip and take jot notes.  Next answer the following questions.
  • What role did the petunia play in the discovery of RNAi?
  • How does RNAi work?
  • Why did cells evolve this mechanism?

2..  Watch the Stem Cells (April 2005) clip and take jot notes.

  • Design 3 questions that could be asked of anyone that sees this clip.

3. Watch the Stem Cells (Update 2006) clip and take jot notes.

  • What information has changed in respect to stem cells since the first clip?


**In addition to the jot notes and questions, please record a podcast of your ORGANIZED thoughts about the following items … (it might help to write a point form note about this topic before your begin your podcast!)

The most interesting thing I learned about stem cells today was…. because… (give at least 2 reasons why it was interesting)

Embryonic stem cell harvesting can be an ethical issue for people.  What are your thoughts about using embryonic stem cells in research and treatments?  Does the switching of a gene within the egg to produce only a blastula and not a viable fetus negate these ethical issues?  Your opinion is welcome… make sure you support it!

**These podcasts will be recorded using the recorder in the comment section.


Activity Two: Stem Cell Interactive (SmartBoard)


Go through the interactive and answer the following questions…
**This interactive does not like Chrome so use Edge or IE.

Take jot notes where you need to but focus on these ideas…

  • Describe the unique characteristics of stem cells.
  • Where do stem cells come from? Discuss some of the challenges in obtaining them?
  • What are the therapeutic uses of stem cells identified in the interactive activity?  Outline them briefly – how are stem cells proposed as a treatment?

Group Discussion

As a group, discuss the therapeutic uses.  Which therapy can you see as the top most viable wide-spread therapy?  Why

Personal Reflection

In a paragraph reflect on the group discussion.  Did you opinion differ from the others?  Why?  How did you reach a consensus?  How did the ‘top therapy’ win you over?  Give the reasons.

Submit your jot notes and paragraph

Activity Three: Heart Rate and Blood Pressure


You… a blood pressure cuff and a timer. (I suggest staggering your times by 30sec to 1 minute)


1. Rest for 5 minutes – sit and do nothing!
2. Take your BP and HR.
3. Run for 5 minutes
4. Take your BP and HR.
5. Rest for 5 minutes, take vitals.
6. Continue to rest, take vitals in 5 minutes
7. Continue to rest, take vitals in 5 minutes… (15 minutes of rest.)


1. Graph your results. Put BP on the y-axis left side and HR on the right side, and time (experience).
2. How does your recovery time compare with the recovery time of others in your group?
3. Explain the reason for the pulse and blood pressure changes.
4. How does recovery time indicate level of fitness? Explain.
5. Research to find the normal rates for a person your age. How does your pulse rate compare? What are some of the reasons for the differences?
6. Describe any difficulties you had with running this lab. Is there anything that you would do differently?
Submit your answer to the questions.  No formal lab required.
Activity Four: Animal Systems

Obtain a textbook and read and note 64-71.  Your notes should include details of each organ system – put the table in your notes that is provided.  Draw figures 2.23 and 2.25 (put them into your notes where appropriate).

Work through the interactive – Tissues and Human Organs.  Note anything that supplements your notes from the textbook.  Some additional ideas can be guided by answering the following questions

  1. Complete the following table. Point form is acceptable.
Type of animal tissue Function of tissue Organs that have this tissue
Epithelial tissues
Connective tissue
Muscle tissues
Nervous tissues
  1. Name the three types of muscle tissue you have in your body, give one location of each type, and state if it is voluntary or involuntary.
  2. Why does the stomach have muscle tissue and nervous tissue? Explain.
  3. What are the differences between the veins and arteries?
  4. What have you learned about tissues and organs from doing this experiment?

Begin to colour the Organ Systems ‘Colouring Book’!!  This will supplement your notes without you spending the time to ‘draw’ all figures!

Submit your notes and the questions. (I am not assessing your colouring…)

Activity Five: Dissection... coming soon.
