Today's science session covered ecology and taxonomy. Ecology lessons included defining ecosystems as consisting of biotic (living) and abiotic (non-living) components. Taxonomy lessons reviewed the hierarchical order of classification from kingdom to species, and discussed the five main kingdoms including the animal kingdom and its representative phyla such as porifera, echinodermata, cnidaria, and others. The session concluded with a review of the chordate class and its vertebrate subgroups.
