Scaffolding Questions:
 What is required/needed for a chemical reaction to occur?
 What are some indications that a chemical reaction has
occurred?
 Can you identify some of chemicals/reactants/products in
these pictures?
 Are you able to draw some parallels between the chemical
reactions occurring in a laboratory and the real life
applications?
Placemat Activity
Misconceptions
1. Students have difficulty with nomenclature, specifically with
naming chemical compounds and using the cross-over rule.
Nomenclature Review:
Write out the name for the following compounds:
Al3+ O2+
1.
2.
3.
4.
5.
NaCl ______________________________
Na2O ______________________________
Ca3N2 ______________________________
CaBr2 ______________________________
NO2 _______________________________
Write out the formula for the following compounds. (Show the cross-over method):
1.
2.
3.
4.
5.
Calcium Chloride_______________________________
Aluminum Bromide ____________________________
Lead Nitrate ___________________________________
Sodium Hydroxide______________________________
Calcium Carbonate______________________________
Al2O3
2. The reactants and products in chemical reactions can
always be distinguished from one another.
3. Students have difficulty differentiating between a chemical
change and a change of state, which is when a physical
change occurs.
4. In a chemical reaction the mass is conserved, but not
the number or species of atoms.
5. Chemical reactions must be driven by external
intervention for example heat.
Prior Mixing:
Post Mixing:
6. Elements can form other elements.
Jigsaw
Instructions
 In your expert group, Build a molecular model of an
example of a chemical reaction that has been assigned
 In your home group, Make a drawing of your molecular
model or act out all of the chemical reaction processes
Blog Activity
 The Overview
As this unit begins I would like to tell you about the blog assignment for the Chemical
Reactions Unit. Since blogging allows for a student-centered course and a deeper
interest in the materials I have made a blog an integral part of the course.
Assignment Description
Your assignment is to create and participate in our class blog. You will be required to
write one entry related to chemical reactions. You will be responsible for tracking your
entry throughout the unit. By tracking I mean that you will be required to pay attention
to your post and address any questions and discussions related to your post.
Your post should address how class materials, subjects and lessons are relevant to
industry, everyday life and/or technology. You are encouraged to be creative and research
using multiple media sources. You post should include an audio, visual or video
component.
In addition to posting your own entries, you are required to actively read other blogs
and other students’ entries. Your active engagement will come in the form
commenting on at least 3 other blogs.
