Educate
Science Friday partners with educators and scientists to create free STEM activities, lessons, and resources for all learners.
What is Nanotechnology?
Nanotechnology is the study of what happens when things get very, very small – only a few atoms in size. The word “nanometer” means one billionth of a meter, perhaps five or six atoms long. At the nanoscale, materials can have very different physical or chemical properties, even though they are the same. In particular, super thin films of material, only a few nanometers thick, can cause interference within light reflecting off them, resulting in beautiful displays of colors.
Gassy Microbes
Some microbes produce different types of gases as a byproduct of their metabolic processes. The microbes in this Science Friday Video released an odorless and flammable gas called methane. The type of gas or gases released by a microbe depends on the species and their metabolic characteristics. In this activity, students will conduct an experiment to observe the metabolic process of yeast by using household ingredients. Students will vary conditions in the yeast’s surrounding environment and observe the amount of gas that the yeast releases
Mushroom Prints
In this lesson, students will be amateur mycologists–collecting and analyzing various mushrooms. Through observation and discussion, students will gain knowledge of the basic anatomy of mushrooms, their life cycle, and their method of reproduction through spores. Students will learn to create spore prints of mushrooms and label and preserve their spore prints, just like a mycologist. Students also will learn that by comparing spore prints, they can identify different mushroom species.
