1. Types of Reactions

2. Synthesis Two or more simple reactants combine to form one product Dating Analogy: synthesis is like a happy couple getting together. A + B  AB In your small group, talk about how you could represent this type of reaction using shapes, then draw your idea in your notes Add your observations of the actual synthesis reaction from the video clip. Build a model of this reaction using legos. Draw your model in your notes.

3. Decomposition One reactant breaks down into two or more simpler products Dating Analogy: Decomposition is like the break up AB  A + B Discuss with your small group, then draw this reaction using shapes. Add your observations of the actual decomposition reaction from the video clip. Build a model of this reaction using legos. Draw your model in your notes.

4. Single Replacement (or Single Displacement) A single element replaces another in a compound to form a new compound and a different single element in the products Dating Analogy: Single Replacement is when a happy couple goes to a school dance but one of them ends up with someone who came to the dance alone. AB + C  AC + B Discuss with your small group, then draw this reaction using shapes. Add your observations of the actual single replacement reaction from the video clip. Build a model of this reaction using legos. Draw your model in your notes.

5. Double Replacement (or Double Displacement) Two elements in two different compounds switch places to form two new compounds Dating Analogy: Double replacement is a blind double date where the boys and the girls both decide they like their friend’s date better so they switch AB + CD  AD + CB Discuss with your small group, then draw this reaction using shapes. Add your observations of the actual double replacement reaction from the video clip. Build a model of this reaction using legos. Draw your model in your notes.
