Ever wonder how aquatic ecosystems really thrive? 🌊 The secret to their energy flow lies in something you might overlook every day — photosynthesis and respiration! This is similar to the Primary Productivity lab you'll see in your APES class!
In this AP® Environmental Science experiment, UWorld’s Dr. Simon takes you underwater (well, sort of!) to measure Net Primary Productivity (NPP) using aquatic plants, light vs. dark bottles, and a dissolved oxygen meter. By tracking how oxygen levels change, we’ll uncover how much energy plants store for consumers in the ecosystem.
What you’ll learn:
0:00 - Introduction to GPP and NPP
0:45 - What is NPP?
1:36 - Photosynthesis and Respiration Explained
3:25 - The Experiment: Materials and Setup
4:22 - Measuring the Baseline
4:55 - Setting up the Flasks
6:35 - Incubating the Experiment
7:50 - Checking on the Results
10:15 - Measuring Dissolved Oxygen
11:32 - Calculating GPP and NPP
13:45 - Final NPP Calculation
14:33 - Conclusion
Aquatic plants aren’t just scenery — they’re energy powerhouses driving entire ecosystems. Join us as we dive into the science that powers life beneath the surface!
