Download Biology 12 Excretion Project Task: To make a screencast or other

Biology 12 Excretion Project
Task: To make a screencast or other video to demonstrate your mastery of the learning outcomes for
the Excretion Unit.
Details: You will work in groups of 2-3. Your screencast/video will consist of your voice(s) explaining the
Excretion System, with the use of visuals. For example, you may use a mouse or stylus to highlight the
structure of a nephron as you explain its function. You are welcome to make a normal video using a
camera but I would encourage you to experiment with some new technology. Screencasting is an easy
way to illustrate a concept and you may use it in future projects!
Suggested software/apps for screencasting: “Jing” for PC, “Explain Everything” or “Educreations” for
iPad, iMovie for Mac. You are welcome to use my computer, but please make an appointment as soon
as possible. See my website for examples using Jing and Explain Everything.
Due Date: ________________________. Your screencast/video must be sent by link, such as a YouTube
link. If you are making a normal video (not a screencast) you might want to try the “Mail Vu” app.
If you have a creative idea or an alternative to my suggested software/apps, please let me know!
Criteria:
Each learning outcome MUST be included. Save time by labelling some of the parts before recording.

o loop of Henle
describe the production of urine with reference to the following terms:
o pressure filtration
o selective reabsorption
o reabsorption of water following an osmotic gradient
o tubular excretion
o metabolic waste (e.g., nitrogenous waste, urea, ammonia)
describe how the kidneys maintain blood pH
compare urea and glucose content of blood in the renal artery with that of the
renal vein
identify the source glands for antidiuretic hormone (ADH) and aldosterone
describe how the hypothalamus, posterior pituitary, ADH, and the nephron
achieve homeostasis of water levels in the blood
describe how the adrenal cortex, aldosterone, and the nephron achieve
homeostasis of water and sodium levels in the blood
Oral Interview Questions:
After viewing your video, I will pull each group out of class to ask several questions
about your video and the Excretory System. Each member of the group is expected to
answer any question
