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.
A good guideline of when to stop feeding hummingbirds is to leave your Hummingbird feeder up for about 2 weeks after your Hummingbirds have left for the season. This will provide nectar for any Humming birds that might have gotten a late start on their southward migration due to illness, injury or other reasons.
