At one time wetlands were known only for being the mosquito-breeding grounds they can be. Thus, management practices included eliminating the wetland altogether. It is now known that wetlands have at least three useful functions for human inhabitants: pollutant filter, flood mitigator, and site of exceptional biodiversity compared to adjacent dry land areas. How can […]

Most kids are familiar with the migration patterns of monarch butterflies and Canada geese, but do they know that many more animals are seasonal movers too? The National Science Education Standards point out that middle school students are capable of broadening their understanding of how many different species interact, compete, and coexist in the same […]

In their study of the life sciences, middle school students are making the transition from thinking strictly about individual organisms to developing an understanding of patterns of life found in ecosystems. The National Science Education Standards call for middle school students to analyze the internal structures, chemical processes, and common ancestry of all species, including […]

April showers bring May flowers—and their pollinators. Many angiosperms, i.e., flowering plants, depend upon animals for species survival. If pollination fails, no new seeds (or fruits) are produced, genetic diversity declines, and the plant population could become threatened. Plants have various adaptations that increase the likelihood of successful pollination. Some require insect pollinators, some bird, […]

Middle school students often have a rather generic concept of plants, failing to recognize the incredible diversity of plants. Unless students are widely traveled, it is unlikely their concept of plant diversity will expand without some intervention. Here are a few resources that can help you impart ideas of species diversity, biological classification, and adaptations, […]

Planning your spring units? Most kids (and their teachers) love to get into the “field” to do science. Many schools have access to streams and to outreach programs in which state departments of natural resources (DNR) work with schools to survey the biodiversity and abiotic conditions of local streams. The DNRs also have the necessary […]
