Plan and Conduct an Inquiry
Purpose
Your task is to plan and conduct a lab activity into how ONE of the following factors affect the rate of a chemical reaction: change in temperature (ex. hot vs. cold water), increased surface area (i.e. particle size), change in concentration or increased pressure.
Possible questions for testing:
You are to design a lab report to test these factors using only the necessary materials below:
