Essential Questions >
  • How do scientist classify life… even life that is as small and simple as microbes?
    • Where can we find microbes (bacteria & fungi)?
    • What is exponential growth?
    • How to microbes influence the food we eat?
    • What are the Kingdoms of Life?
You will KNOW that….
Key vocabulary terms such as:
  • Microbe, Moneran, Protist, Fungi, Plant, Animal, Kingdoms, Taxonomist, Bacteria, Prokaryotes, Eukaryotes, Microbes, Sterile, Inoculate, Dichotomous Key, Virus, exponential growth, decomposer, cocci, spirilli, bacilli, genus, species
It’s important to understand that…
  1. Microbes are microscopic bacteria, fungi, & viruses that can be both helpful and harmful.
  2. Bacteria and fungi have the characteristics of life but viruses do not.
  3. Bacteria are prokaryotes and do not have a nucleus or complex organelles.
  4. Microbes are on all surfaces, in water, and in the air.
  5. There are five/six kingdoms that all life is classified into
  6. How to use a dichotomous key and evolution chart.
You will be able to….# Demonstrate their ability to test for the presence of microbes utilizing sterile agar and bread as growing mediums.
  1. Describe how microbes are used to transform foods and recycle nutrients.
  2. Create a dichotomous key to classify organisms.


EQ: Where can we find microbes?

  • You will inoculate sterile petri dishes and bread to test for the presence of microbes in our classroom. (Lab book pages 67-69)
  • You will view the NOVA video "The Unknown World" [link below] and complete lab book pages 72 & 73 (Lab book pages 67-69)

The Unknown World
  • You will study the link below to see where microbes might live in your house.

Microbe survey of the New York City Subway System

  • You can view the very cool "Microbe Zoo" (Below) to see amazing places where microbes exist.
  • Microbe Zoo


EQ: What is exponential growth?

  • You will discover the concept of exponential growth via lab book activity (pages 70 & 71) and link below.

EXPONENTIAL Growth Activity

You can use the link above to plot the data (x,y) coordinates to plot the graph on page 71 of your lab book if you did not get to do the activity in class.

Understanding Exponential Growth


EQ: How do microbes influence the food we eat?

  • You will discover microbes help make our food via lab book activity (pages 74 - 78) and link below.
  • If you are not in class the day we do this, try to do this at home with an adult's help.
