Week 14 Rates of Reactions: Jan 14 - 18

Goals:
1. Know and be able to apply the vocabulary: variable, independent variable, dependent variable, controlled variable.
2. Understand what happens to the molecules of a substance as its temperature increases.
3. Be able to compare the speeds (rates) of a reaction through using graphs.
4. Know how temperature affects the speed (rate) of a reaction, and be able to explain this effect with the particle model.

Activities
Mon :Introduce experiment. Work on Graphing practice worksheet. Hypothesize about what affects the rates of chemical reactions. Hypothesize about the affects of temperature on particle behavior.
Tues: Reaction Rate Experiment (Hot trial) Link to handout, Homework: Finish Graph of Results
Thursday : Reaction rate experiment (Cold trial) Graph, discuss experiment results and finish worksheets.
Friday: Review and quiz. Start Hypothesis Forming Worksheet. Finish as Homework.

Notebook Contents:
