The guided inquiry activity enables students to identify the five basic types of reactions - synthesis or composition, decomposition, combustion, single replacement and double replacement. Students will also begin to predict the products for each of these types of reactions. The activity was developed in cooperation with Michelle Holdbrooks of Thompson High School.
This lesson plan was created as a result of the Girls Engaged in Math and Science University, GEMS-U Project.
Primary Learning Objective(s):
The students will
(a) use picture cards to define the five types of reactions and write generic reactions for each type
(b) match the type of reaction to actual chemical reactions
(c) match the products to the correct reactants
Additional Learning Objective(s):
31 to 60 Minutes
Materials and Resources:
card stock, gallon size plastic baggies, 2" x 4" labels
The teacher will need to print the picture cards illustrating the types of reactions, the template for the example reactions, the reaction type cards, and the products cards on card stock. It is recommended that the teacher use different color card stock for each type of card to be printed. The picture cards should be printed on white card stock. The printable materials can be laminated to ensure durability. Place all the materials in the same plastic baggie and label. This material can also be used with an interactive white board.
Technology Resources Needed:
computer and LCD projector
Extension/Remediation: individual computers or group computers
After the students have developed the definitions for the types of reactions using the picture cards and reaction type cards, the teacher can display the PowerPoint presentation about reaction types on a loop while the students continue the activity.
The teacher will need to know the five types of reactions - synthesis or composition, decomposition, combustion, single replacement, and double replacement. The teacher will also need to know how to predict the products for each type of reaction. Students will need to know the basic parts of chemical reactions - reactants, products, and yield.
The major concepts are determining the types of reactions and predicting products for each type of reaction.
The teacher can use the rubric
to evaluate the progress of the students through the various levels of the activity.
The assessment worksheet
is an additional check of the student's understanding and can be used to evaluate individual understanding of the concept.
Students can practice types of reactions at the following websites:
The reaction type study cards can be printed for the students who need additional assistance with reaction types and predicting products.
Students can also review the material using the following websites:

for students with identified learning and/or behavior problems such as: reading
or math performance below grade level; test or classroom assignments/quizzes at
a failing level; failure to complete assignments independently; difficulty with
short-term memory, abstract concepts, staying on task, or following directions;
poor peer interaction or temper tantrums, and other learning or behavior problems.
