4 Minds-on Chemical Reactions Video: ChemicalReactions_Video.wmv 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?
6 Misconceptions1. 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:NaCl ______________________________Na2O ______________________________Ca3N2 ______________________________CaBr2 ______________________________NO2 _______________________________Write out the formula for the following compounds. (Show the cross-over method):Calcium Chloride_______________________________Aluminum Bromide ____________________________Lead Nitrate ___________________________________Sodium Hydroxide______________________________Calcium Carbonate______________________________Al3+ O2+Al2O3
7 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.
8 4. In a chemical reaction the mass is conserved, but not the number or species of atoms.
9 5. Chemical reactions must be driven by external intervention for example heat. Prior Mixing: Post Mixing:

13 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.
