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.
Do your homework and find out when to expect the spring return of hummingbirds in your area. Hang nectar feeders about 5-10 days before this date to ensure hummingbirds see them, take a drink, and are tempted to stay all season long. Remove feeders a couple weeks after you see your last visitors in the fall.
