chemical bonding 5E Lesson Plan

At the end of this chemical bonding lesson plan, students will be able to describe how elements form bonds, investigate how valence electrons relate to chemical bonds, and differentiate between ionic and covalent bonding.  Each lesson is designed using the 5E method of instruction to ensure maximum comprehension by the students.

The following post will walk you through each of the steps and activities of the chemical bonding lesson plan.

ENGAGEMENT

Objective Introduction

At the beginning of the lesson, the class will do a Think-Pair-Share to discuss the objective.

Class Activity

  1. Write these words on the board:
    • Ionic Bonds
    • Covalent Bonds
  2. Show the animated video – The Chemical Bonds Song. The link is provided.
  3. Explain to students they will be taking notes during the video.

Student Activity

  1. Have students break up into small groups.
  2. In each group, have students discuss and compare their notes with each member of the group.
  3. Have students try to explain Ionic Bonding.
  4. Have students try to explain Covalent Bonding.
  5. Play the song again to allow students an opportunity to add to their explanations of both bond types.

The teacher will help to clear any misconceptions about chemical bonding. A major misconception is students may think they can acquire dichotomous classification of bonds readily, but fail to understand that bonding is primarily an electrical phenomenon. This is an area where helping students to appreciate that our descriptions and diagrams are just models will make learning easier.

Estimated Class Time for the Engagement: 20-30 minutes

EXPLORATION

This student-centered station lab is set up so students can begin to explore chemical bonding. Four of the stations are considered input stations where students are learning new information about chemical bonding, and four of the stations are output stations where students will be demonstrating their mastery of the input stations.  Each of the stations is differentiated to challenge students using a different learning style.  You can read more about how I set up the station labs here.

EXPLORE IT!

Students will be working in pairs to identify the types of chemical bonds. Students will follow the directions on the task cards and use manipulatives to show how valence electrons in atoms combine to form chemical bonds. Students will be demonstrating the bonds of H2O and NaCl. Throughout the process, task cards will continue to assist students to understand the differences between ionic and covalent bonds.

WATCH IT!

At this station, students will be watching a nine-minute video explaining the differences between covalent and ionic bonding. Students will then answer questions related to the video and record their answers on their lab station sheet. For example, what are the differences between covalent and ionic bonds? Describe the octet rule. What type of bonds would be in CO2?

RESEARCH IT!

The research station will allow students to explore an interactive webpage that has students take a scientific approach to understanding chemical bonds. Students will be instructed to complete a few tasks and record answers on their lab sheets.Chemical Bonding 5E Lesson

READ IT!

This station will provide students with a one page reading about why are bonds important. In the reading, students will discover many forms of chemical bonds, what happens when chemical bonds break, and examples of energy production. There are 4 follow-up questions that the students will answer to show reading comprehension of the subject.

ASSESS IT!

The assess it station is where students will go to prove mastery over the concepts they learned in the lab.  The questions are set up in a standardized format with multiple choice answers.  Some questions include: What type of bonds are shown in the pictures? Which two elements are most likely to bond with each other? Fill in the blank: ____ bonds share valence electrons with other atoms.Chemical Bonding 5E Lesson

WRITE IT!

Students who can answer open-ended questions about the lab truly understand the concepts that are being taught.  At this station, the students will be answering three task cards to describe the valence electrons in nitrogen and how it could bond to other atoms. Students will also answer in their own words how are ionic bonds are different from covalent bonds, and why atoms are attracted to each other in an ionic bond.

ILLUSTRATE IT!

Your visual students will love this station. Students will draw two diagrams to show how atoms bond with each other to create chemical molecules. Students will identify the diagrams as either a covalent bond or ionic bond.Chemical Bonding 5E Lesson

ORGANIZE IT!

The organize it station allows your students to manipulate cards in the correct column by whether the information is describing that of covalent bonds or ionic bonds.

Estimated Class Time for the Exploration: 1-2, 45 minute class periods

EXPLANATION

The explanation activities will become much more engaging for the class once they have completed the exploration station lab.  During the explanation piece, the teacher will be clearing up any misconceptions about chemical bonding with an interactive PowerPoint, anchor charts, and interactive notebook activities. The chemical bonding lesson includes a PowerPoint with activities scattered throughout to keep the students engaged.Chemical Bonding 5E LessonChemical Bonding 5E Lesson

The students will also be interacting with their journals using INB templates for chemical bonding.  Each INB activity is designed to help students compartmentalize information for a greater understanding of the concept.  The chemical bonding INB template allows students to focus their notes on identifying the differences between covalent and ionic bonds.Chemical Bonding 5E LessonEstimated Class Time for the Exploration: 2-3, 45 minute class periods

ELABORATION

The elaboration section of the 5E method of instruction is intended to give students choice on how they can prove mastery of the concept.  When students are given choice the ‘buy-in’ is much greater than when the teacher tells them the project they will have to create.  The elaboration project will allow students to create a presentation to teach about chemical bonding.Chemical Bonding 5E LessonEstimated Class Time for the Elaboration: 2-3, 45 minute class periods (can also be used as an at-home project)

EVALUATION

The final piece of the 5E model is to evaluate student comprehension.  Included in every 5E lesson is a homework assignment, assessment, and modified assessment.  Research has shown that homework needs to be meaningful and applicable to real-world activities in order to be effective.  When possible, I like to give open-ended assessments to truly gauge the student’s comprehension.

Estimated Class Time for the Elaboration: 1, 45 minute class period
