Grade 11 Chemistry ( SCH3U)
Guiding Questions A1. Demonstrate scientific investigation skills in the four areas of skills (IP, PR, AI, C) C1. Analyse chemical reactions used in a variety of applications and assess their impact on society and the environment C2. Investigate different types of chemical reactions C3. Demonstrate an understanding of the different types of chemical reactions 1. Chemicals react in predictable ways 2. Chemical reactions and their applications have significant implications for society and the environment Overarching Question Big Ideas How can we predict how chemicals react and what implications do the applications of chemical reactions have on society and the environment? Overall Expectations 1. What are the different types of chemical reactions and what do they look like? 2. How are chemical reactions used in a variety of applications and what are their impacts on society and the environment?

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?
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: 1.NaCl ______________________________ 2.Na 2 O ______________________________ 3.Ca 3 N 2 ______________________________ 4.CaBr 2 ______________________________ 5.NO 2 _______________________________ Write out the formula for the following compounds. (Show the cross-over method): 1.Calcium Chloride_______________________________ 2.Aluminum Bromide ____________________________ 3.Lead Nitrate ___________________________________ 4.Sodium Hydroxide______________________________ 5.Calcium Carbonate______________________________ Al 3+ O 2+ Al 2 O 3
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.
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.
