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.
Plants: Hummingbirds feed frequently on nectar-rich flowers, and planting flowers specifically to attract these flying jewels is an easy way to make any yard a perfect hummingbird habitat. While the color red is very attractive to hummingbirds, the most important factor is that the flowers must produce plenty of nectar. Bleeding hearts, impatiens, petunias, salvias, bee balm, columbine, cannas, viburnums, honeysuckles and many other flower, tree and shrub species will attract a variety of hummingbirds.
