Assignment task:
In your responses:
Evaluate the proposed hypotheses presented by other students, identifying possible strengths or weaknesses in the overall method
Suggest an alternative testable hypothesis for the phenomenon they've presented
Explain why your hypothesis adds to the overall scientific methods in this case.
When responding to the work of others, vary your exposure to other taxa (i.e. other groups of algae) by choosing students who are focused on species from different taxonomic groups, so that one of your responses is to someone who's done a different group (i.e. if you did your assignment on a red alga, you should look for someone who did theirs on a green or brown algae, etc.), and the other is to a group more similar to yours. If you don't see any such options, or those students have already received feedback from two others, then find the next best option, even if it's similar to your work. You will not be penalized for your interaction choices - but it is important to get varied feedback and expose yourself to other groups. Need Assignment Help?
My species: sugar kelp
Peer's post:
Observation:
While snorkeling near a reef, I noticed that seagrass beds near areas with high boat traffic looked patchier and less healthy than those in quieter areas.
Hypothesis:
High levels of boat traffic reduce seagrass growth due to increased sediment disturbance and light blockage.
Method to Test Hypothesis:
I would compare two seagrass bed areas: one near heavy boat traffic and one in a protected, low-traffic area. Over three months, I'd measure seagrass density, blade length, and water clarity weekly. I would also collect sediment samples to see how much is suspended in the water at both locations. A control setup could include small underwater enclosures to reduce other environmental factors.
Potential for Future Research:
If the hypothesis is supported, further studies could test how different types of boats (e.g., speedboats vs. kayaks) or different water depths affect sediment disturbance. Research could also explore how to protect or restore seagrass beds in busy boating areas using barriers or regulations.
