The lesson ties into the concepts of survival and extinction of multicellular organisms from the previous lessons. R: Students rethink how organisms respond to the environment as they design an experiment on one of the pond water microorganisms from the previous lesson. E: Students express their understanding on the worksheet, in class discussion, and in groups as they work to design an experiment.
Itâs too late to attract a western hummer this winter, but perhaps youâd like to try next fall. According to Weidensaul, in addition to keeping hummingbird feeders up well into autumn, many successful hummingbird hosts have late-blooming fall plants.
September is typically the most satisfying month to feed hummingbirds. As the nights become regularly cold, rubythroats begin to migrate south. This occurs in Missouri in late September, and by October 10 the rubythroats are usually gone. That's a good time to bring in the feeders and clean them for winter storage.
