Chemical Bonding Lesson Plan

Instructor: Adrianne Baron

Adrianne has taught high school and college biology and has a master's degree in cancer biology.

Chemical bonds are everywhere in our environment. Your students will learn the basics about chemical bonds as they watch a video, create and view books of chemical bonds, and take a quiz.

Learning Objectives

At the completion of this lesson, students will be able to:

  • Define chemical bonding
  • Identify and demonstrate the different types of chemical bonds


1.5 hours

Curriculum Standards


Cite specific textual evidence to support analysis of science and technical texts, attending to the precise details of explanations or descriptions.


Determine the meaning of symbols, key terms, and other domain-specific words and phrases as they are used in a specific scientific or technical context relevant to grades 9-10 texts and topics.


Translate quantitative or technical information expressed in words in a text into visual form (e.g., a table or chart) and translate information expressed visually or mathematically (e.g., in an equation) into words.


  • Computer with projector
  • Copies of the lesson quiz
  • Printer paper
  • Colored pencils


  • Begin this lesson by explaining to your students that everything in our world is held together by chemical bonds since everything is composed of chemicals. Tell them they are going to learn about how their bodies and everything in their world is held together by chemical bonds as they watch the Overview of Chemical Bonds video.
  • Play the video for your students and pause it for periodic discussions
  • Pause the video at 1:06, then ask and discuss:
    • What are chemicals?
    • What is a chemical bond?
    • What are the two most common types of chemical bonds?
  • Continue playing the video and pause at 2:19 to ask and discuss:
    • What is an ionic bond?
    • Which of the three atom particles moves during chemical bonding?
    • What types of chemicals tends to form ionic bonds?
    • Why are they more prone to form ionic bonds?
  • Continue playing the video and pause it again at 3:06. Ask and discuss:
    • What is a covalent bond?
    • What is the status of the outer shell of electrons that promotes covalent bonding?
    • What types of chemicals are most likely to form covalent bonds?
  • Continue the video, pausing it again at 3:45 to ask and discuss:
    • What is a polar covalent bond?
    • How does a polar covalent bond alter the charges on the atoms in the bond?
    • What is a metallic bond?
    • How are electrons arranged in metals?
  • Play the rest of the video for your students and answer any questions they have.
