Curriculum Standards


Cite specific textual evidence to support analysis of science and technical texts, attending to important distinctions the author makes and to any gaps or inconsistencies in the account.


Integrate and evaluate multiple sources of information presented in diverse formats and media (e.g., quantitative data, video, multimedia) in order to address a question or solve a problem.


  • Copies of the lesson quiz
  • Computer with projector
  • Student computers
  • Poster board
  • Art supplies (colored pencils, markers, glue and scissors)


  • Begin your lesson by asking what your students think about when they hear the word 'microbe'. Write some of their answers on the board. Students will usually give negative thoughts, so ask them if they have any positive thoughts about microbes as well.
  • Let them know they may be surprised at how much they actually like what microbes do in addition to not liking the illnesses they cause. Tell them that you are going to learn more about microbes as you watch and discuss the What Are Microbes? - Definition, Types & Uses video lesson.
  • Start the video and pause it periodically to have discussions with your students.
  • Pause at 1:00, ask these questions:
    • What is a microbe?
    • Are there good and bad microbes?
  • Pause at 2:30, ask these questions:
    • Where are some of the places where we can find microbes?
    • Are there microbes in our bodies?
    • What are the five main groups of microbes?
  • Pause at 5:22, ask and discuss:
    • Which species of bacteria help our intestines to digest food?
    • What is a helpful use for fungi?
    • What are some diseases caused by protozoans?
  • Play the remainder of the lesson, answering any remaining questions.


  • Give your students the lesson quiz.
  • Go over the quiz answers together as a class.

I would definitely recommend to my colleagues. It’s like a teacher waved a magic wand and did the work for me. I feel like it’s a lifeline.
