Objective:  Factors that Affect the Rate of a Chemical Reaction

Big Idea Application:
During chemical processes matter can change forms.

The overarching essential questions being considered:
What happens during a chemical reaction?

Objective:  Conservation of Matter

Big Idea Application:
During ordinary physical or chemical processes matter can neither be created nor destroyed.  It can only change forms.

The overarching essential questions being considered:
What happens during a chemical reaction?

Objective: Observe Evidence of Chemical Reactions

Performance Tasks:

Closed Chemistry- Design and build a closed structure in which a chemical reaction can occur.  You will present your demonstration to the class providing evidence for conservation of mass.  The presentation should include a poster of the balanced chemical equation for your reaction.

Introduction

Summary
Here you will find a toolbox full of inquiry investigations on photosynthesis and respiration. Rather than the detailed lesson plans provided elsewhere at My Science Box, each experiment only contains a short background, materials, procedure, and going further section. It is up to you to decide which of the many experiments you wish to try with your students and how to sequence them. You will find everything from descriptions for how to extract chlorophyll, discover that plants “breathe”, recreate the experiments of Priestly and Ingenhousz, detect carbon dioxide production, and measure the rate of yeast respiration. None of these experiments require expensive equipment such as metabolism chambers or oxygen meters although those are great tools if you can afford them.
