PASCO EcoZone system bestaande uit 3 glasheldere onderling verbonden kamers op grondplaat. (let op nr. ME-6668 is alleen de kamer dus zonder sensoren. e.d.) Introducing PASCO's new EcoZone System! The interaction of organisms within their physical surroundings is one of the most important concepts within Environmental Science. Traditionally, efforts to study ecosystems have been limited to observational, qualitative studies. Now PASCO allows you to make these studies quantitative. Do not spend valuable time on set up and clean up! Cutting two liter soda bottles, removing labels, poking holes, connecting chambers, all of this is done for you! Eliminate the wasted time in setting up ecosystems and utilize it to study the ecosystem instead. Clean up is easy, and the chambers are durable enough to use again and again. The unique design of the PASCO EcoZone System allows you to use your environmental science probes to actively measure a model ecosystem. What makes this system truly unique? -Your measurements have minimal impact on the system because it remains closed! -Custom built to easily interface with PASCO line of sensors and interfaces. -Decouple the EcoChambers for individual studies of single ecosystems. 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 openings within the chambers allow air to circulate between the chambers, and the included cord efficiently wicks water between the chambers. Additionally, ions are transported through the cord, so materials move from the terrestrial chamber too!
