Types Of Chemical Reaction Lesson Plan for 10th Grade Students

Topic: Types of Chemical Reaction

Objectives & Outcomes

• Students will be able to identify and describe the characteristics of different types of chemical reactions (e.g. combination, oxidation-reduction, replacement, double displacement).

Materials

• Flashcards with examples of different types of chemical reactions
• Handouts with descriptions of the different types of chemical reactions
• Whiteboard and markers

Warm-up

• Review the concept of chemical reactions and how they occur, using examples from previous lessons.
• Ask students to brainstorm a list of different types of objects that could take part in a chemical reaction (e.g. chemicals, objects, organisms).
• Review the list with the students and discuss the types of chemical reactions that could be caused by each object.

Direct Instruction

• Distinguishing between different types of chemical reactions and their characteristics is an important skill for chemists to have.
• Introduce the three main types of chemical reactions (non-chemical, chemical, and thermal) and discuss the characteristics of each.
• Use examples and demonstrations to help illustrate the differences between the types of chemical reactions.
• Ask students to consider the different types of objects that could take part in each type of chemical reaction and brainstorm a list.

Guided Practice

• Have students work in pairs to complete a matching activity, where they match a list of objects to the correct type of chemical reaction they could take part in. -For example, a pencil could be used in a non-chemical reaction (due to its non-biological nature) but not in a thermal reaction (due to its inability to combust on its own).
• As a class, go over the answers and discuss any questions or misunderstandings.

Independent Practice

• Perform a small-scale experiment to test the effect of different types of chemical reactions on a piece of paper. For example, one piece of paper could be placed in a beaker of water, while another is placed in a beaker of alcohol.
• Observe the reactions, and record any changes in the appearance of the paper.
• Use the results of the experiment to create a graph or table that shows the differences between the types of chemical reactions.

Closure

• Review the key points of the lesson, including the different types of chemical reactions and how they can be distinguished.
• Ask students to share their favorite part of the lesson, and why they found it interesting.

Assessment

• Collect and grade their posters as a form of assessment.
• Administer a quiz to assess their understanding of the different types of chemical reactions and how they can be distinguished.
