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.
The reasons for this misperception are several: they are active in the daylight hours (most moths are not); they hover in front of flowers to feed; the probe the flowers for their nectar (although using a proboscis, not a beak); and they favor some of the same nectar-rich blossoms that are liked by hummingbirds.
