They're alive!!! Hopefully they'll stay that way...

Here are some samples of the ecosystems created today. The students did a great job and the ecosystems look great!

Ecosystem in a Bottle!

Tomorrow is the big day that we will put our ecosystems together. Students have been measuring biomass and calculating how many producers, consumers, and decomposers they want to put in their ecosystems. After the ecosystems are set up, we will measure ammonia and nitrogen levels in the water, as well as dissolved oxygen. We will graph this over time to see how our ecosystems are doing. I am really excited for these (photos will be coming shortly). Parents, feel free to come in to the school to look at them.
