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.

Each member of the group is expected to answer any question Total: ___________ /50 (will be divided by two) /10 /2 /2 /2 /2 /2 /15
