Food Webs Media
Introduced in Functional Groups section of this guide:
Patterns in Nature
In this media assignment you are going to find and capture evidence of a pattern in nature. It could be a pattern or non-living system. Examples of patterns (yours may be similar or different):
-
branching patterns in roots, branches, frost, veins
-
spiraling patterns in flowers, cones, water down a drain
-
sphere shape (reducing surface area) in a sleeping animal, a cactus
Note: this media piece would be a good fit for the Science Concepts portion of the final portfolio. If you find multiple examples of patterns, you could arrange them in a “gallery” in the portfolio.
Upload to Canvas:
-
Your media pieces showing a natural pattern.
-
an explanation of what the pattern is and either how it was created or why it may be important (whichever explanation fits your pattern better).
As always, if you engage in any field work, be aware and travel with others whenever possible.
Media Directions
To be completed after taking the quiz on Canvas.
Upload your patterns in nature media piece to Canvas. Your work can be submitted as a PDF, a word document, a photo of the notes, or even a video. Multiple assignment formats are supported.
Portfolio
Portfolio Directions
This is a good point in the course to add your media pieces and favorite quiz responses to your final portfolio. That way it will be coming together well before the due date (Wednesday of week 11 “finals week). This pattern media piece is a good fit with the Science Concepts outcome.
