PASCO’s EcoZone System is designed to help students model and understand the complex interactions within, and among, different ecosystems. The three clear acrylic EcoChambers are specially designed to accommodate PASCO sensors, making qualitative and quantitative measurements as easy as observing.
With three interconnected chambers, students can model the interaction between three different ecosystems. Choose the traditional terrestrial, aquatic, and decomposition arrangement or create unique biomes to model and measure. Decouple the system for isolated investigations. How does the availability of light affect the ecosystem? Students can create two identical ecosystems and monitor one in light conditions and one in dark.

The traditional mechanical approach to yeast respiration studies used mixed gas volume measurement as a proxy for anaerobic respiration in yeast. This approach lacks determination of which gases were produced and in what volume there were produced. In contrast, PASCO’s oxygen gas, carbon dioxide gas, and ethanol gas sensors provide a quick, convenient, cost-effective way to directly measure oxygen gas, carbon dioxide gas, and ethanol gas produced during yeast respiration.
