OUTCOME: Students will be able to identify the factors that affect the rate of reaction: surface area, volume, concentration, temperature, and the addition of a catalyst.

SCI10-CR4 Investigate the rates of chemical reactions, including factors that affect the rate.
b. Predict how factors such as temperature of the reactant(s), concentration of the reactant(s), surface area of the reactant(s), and the presence or absence of catalysts or inhibitors might affect the rate of a chemical reaction. (S, A)

Here’s what I used for my lesson:
1. Lesson Plan

2. Follow along notes

3. Video– How to speed up a Chemical Reaction (and get a date!)

5. PowerPoint

6. Professional Development: (1), (2)

7. Sample work– this was exactly what I wanted.

OUTCOME: Students will be able to follow a procedure in experimenting the Law of Conservation of Mass.

SCI10-CR3 Represent chemical reactions and conservation of mass symbolically using models, word and skeleton equations, and balanced chemical equations.

a-> Design and safely carry out an experiment to confirm the Law of Conservation of Mass, identifying and controlling major variables

Science 10-Types of Chemical reactions

OUTCOME: Students will be able to identify different reactions as either synthesis, decomposition, single-replacement, double- replacement, and combustion.

SCI 10- CR3 Represent chemical reactions and conservation of mass symbolically using models, word and skeleton equations, and balanced chemical equations.

  1. Categorize chemical reactions as synthesis, decomposition, combustion, single replacement, and double replacement, including acid base neutralization. (S, K, A)

6.How I partnered them off

I really enjoyed teaching this lesson and felt it reached multiple types of learners. The students seemed to really respond to the definition game and the partner work helped students who were struggling to grasp the concept a little extra help.
