WebBefore we explore how and why maple seeds spin, it will be nice to take a minute and think about what a maple seed is. A maple seed is a type of seed known as a samara, or helicopter seed – a seed that flies with wings. And, it comes from the maple tree. It is not the only type of flying tree seed, but is the one I will focus on here. Webexperiments on altered maple seeds in addition to their natural forms. One is to cut the wing in ﬁve steps, and the other is to cut the nut in three steps, progressively. In each experiment, we selected ten seeds, and we ﬁlmed the seed motion after each cut three times. Table 1 shows images of the seeds, their masses, and areas after each cut. WebFlying seeds of sycamore maple tree Acer pseudoplatanus Flying seeds on a sycamore maple tree (Acer pseudoplatanus).
