Grauer 7th Grade Life Science Class: Creating Biomes

From Nick Scacco, Science Teacher: 7th Grade Life Science students have learned about how photosynthesis and respiration work together to balance the amount of CO2 and O2 in the atmosphere. The class built miniature biospheres in class, using large jars with lids as the biosphere containers. The students were given the option to build either an aquatic system that would be filled with water or a terrestrial system that would be filled with soil. If they chose a terrestrial system, they could add desert or tropical plants. They also included small invertebrate decomposers in the system, as well as decorative elements. We added water and sealed the biome jars, and we will continue to check on them during the rest of the school year.
