No School - Observed Columbus Day

Tuesday, October 14, 2014

Describe how energy is stored or released during a chemical reaction
Identify the effect of Entropy (S), Temperature and Enthalpy (H)
Identify Gibbs Free Energy Equation and relate it to a first order algebraic equation
Identify endergonic and exergonic chemical reactions
Identify and describe enzymes as biological catalysts
Define substrates and enzymes

Opener - College Pride Day - BS, M.Ed., M.Ed.
Available Energy (Gibbs Free Energy) Introduction

Review the videos and learn the definitions for the following:
Entropy, Enthalpy, Endergonic, Exergonic, Gibbs Free Energy
Go back and seek to understand the graphs/diagrams shared in the videos

Design an investigation in which catalase breaks down hydrogen peroxide
Measure volumes and time using appropriate tools


Part 1: Overview of Experiment
Bozeman Biology Enzyme Catalysis Experiment

Catalase Experiment

Part 2: Demonstration of Catalase activity
Catalase Experiment

Identify possible variables that can be controlled or manipulated to carry out an independent investigation. Watch videos to get some ideas:
Video Experiments -
Experiment #1,
Experiment #2
Experiment #3
Experiment #4
Experiment #5

Part 3: Discuss Safety Concerns and Personal Protective Equipment Needs for carrying out your investigations.

Part 4: Communicate with your group and come to a consensus about which variable you will manipulate in the investigation for tomorrow.
1 - Write your procedure.
2 - Share your materials and procedures with your teacher.
3 - Begin assembling materials for your experiment.

Prepare for tomorrow's investigation

Plan, design and execute an investigative lab using catalase and hydrogen peroxide.
Measure volume, time and temperature using appropriate tools.

Set up lab area.
Carry out laboratory.
Collect data. Repeat to assure reliability of data.

Communicate results to peers.
Review the types of data available for Enzyme Activity

Part 1: MiniLecture: "The 3 Graphs" for enzymes
1- Energy Diagrams
2- Production of Product/Time
3a- Activity of Enzyme/pH
3b- Activity of Enzyme/temperature

Part 2: Communicate your outcomes to your peers in class
