Blood Buffer Lesson Plan

The intent of this lesson plan is to demonstrate a physiological model of the blood buffer system using an Excel Worksheet to calculate Henderson-Hasselbalch Equations for Bicarbonate/Carbonic Acid Buffer pair in Blood and an Agentsheets game to see a visual representation of the chemical process within the body. This will incorporate LeChatelier’s principle in regards to the equilibrium of acids and bases in a buffer system and show how to calculate the Henderson-Hasselbalch equation to understand the ratio of acid to base equilibrium. The primary file is a lesson plan, accompanied by supplemental files. In the supplemental zipped files, you will find: Student worksheets Lesson plan Powerpoint presentation

From Garbage to Garden

This lesson plan is for a laboratory activity that begins with direct instruction, allows students to explore the simulation, and gives students time to work in groups to create hypotheses concerning the five factors of decomposition. Lesson materials include a direct instruction PowerPoint, worksheets, and the Agent Sheets simulation model. After the initial laboratory, students should have the skills to create a working, real life compost pile. Students should also be motivated to reduce their negative impact on the earth’s ecosystem
