Dear LOR user,

Thank you for being a big part of this community. To better support the initiatives around open educational resources in the state of Michigan, all resources on the Michigan Virtual Learning Object Repository (LOR) are being moved to #GoOpen Michigan (link is external) on September 30th, 2018. During the transition, our LOR will be moved to an archived state, not allowing new user registration or new content to be added. An email with more details was sent to registered users of the LOR in September. To make use of the great resources on the platform, we encourage you to create an account and add your own new resources to the #GoOpen Michigan platform (link is external).

Chemical Reactions Blended Unit

Description: 

In this unit on Chemical reactions students will be able to differentiate between the five different types of chemical reactions of synthesis, decomposition, single replacement, double replacement, and combustion reactions. Students will also be able to apply the Law of Conservation of Matter and Mass towards chemical reactions; specifically balancing chemical reactions. The end goal will be for students to be able to when giving the reactants of a chemical reactions be able to predict the products, write a balanced equation, determine the amount of product produced in the reaction, while also determining the limiting reactant.

Learning Targets: 
Construct and revise an explanation for the outcome of a simple chemical reaction based on the outermost electron states of atoms, trends in the periodic table, and knowledge of the patterns of chemical properties.
Develop a model to illustrate that the release or absorption of energy from a chemical reaction system depends upon the changes in total bond energy.
Apply scientific principles and evidence to provide an explanation about the effects of changing the temperature or concentration of the reacting particles on the rate at which a reaction occurs.
Refine the design of a chemical system by specifying a change in conditions that would produce increased amounts of products at equilibrium.
Use mathematical representations to support the claim that atoms, and therefore mass, are conserved during a chemical reaction.

Student prerequisite skills and knowledge

Students should understand chemical bonding, electroneutrality of ionic bonds, atomic structure, chemical trends found in the periodic table, Conservation of Matter and Mass

What concepts or procedures are being explained or demonstrated in this lesson object?

  • Students will be able to explain that reactions involve the rearrangement of atoms into new substances.

  • Students will be able to identify reactants and products and identify the number of atoms of each element

  • Students will be able to recognize the five different types of chemical reactions

  • Students will be able to compare and contrast the different chemical reactions

  • Students will be able to recognize a balanced equation

What was your experience, both successes and challenges, using this lesson object with your students?

Students must be comfortable in being able to read a chemical formula prior to studying chemical reactions. Many students had difficulty in reading a chemical reactions equation. Therefore, I spent a good portion of time revisiting reaction equations. I also reviewed with students electronegativity prior to introducing the activity series and single and double replacement reactions. In order engage students, they need to be able experience chemical reactions in a face-to f
