All seed must be diagramed on lab sheets. After students have begun to work in groups to understand the dispersal of each seed students will have a chance to observe both a lima been embryo attached to a seed and one by itself under a microscope for closer examination. Students will be given an understanding on how seeds are able to disperse form the original plant that has produced it. They will be able to identify how depending on a seeds size, weight, and outer make up can effect how a seed moves around. As a follow up to this lesson students can be taken on a nature walk on school property to collect different seeds and discuss how they are dispersed.
Students enjoy playing detective and figuring out how seed disperse.
We can measure how well the students understand this lesson by their ability to figure out how seed disperse in nature. Students gain the ability to judge which seed are blown by the wind, eaten by animals and dispersed in animal dropping, and which are carried by animals from one place to another. I enjoy teaching this lesson it has a fast paced introduction and hands on work that hold the students interests. It is easy for me to see that there is a true understanding of this lesson by the majority of the students. For those who are having trouble understanding Mrs. Sloan and the Seton Hall interns are able to give personal attention to.
