Lab 5 Cellular Respiration by Kris Layher Lab 5 Cellular Respiration Introduction Cellular respiration is the procedure of changing the chemical energy of organic molecules into a type that can be used by organisms.
Introduction and Connection to the NGSS and Common Core In this lesson, students design an experiment to provide evidence that plants go through the process of cellular respiration by measuring the acidity level in a jar of germinating pea plants.
Trapped inside a closed jar, as carbon dioxide is produced during cellular respiration, it dissolves in water producing an acidic environment that can be measured using bromthymol blue. Science and Engineering Practices: In this lesson, students design and conduct their own experiment to provide evidence that plants go through cellular respiration.
Thus, they plan an investigation collaboratively, and in the design, they identify independent and dependent variables and controls SP3.
Last, the students construct a written argument supported by evidence and scientific reasoning to support or refute their hypothesis SP7. The focus of this lesson is Energy and Matter. The NGSS asks that students consider the following: Energy may take different forms e.
The transfer of energy can be tracked as energy flows through a designed or natural system. As students recognize that bonds are broken and reformed during cellular respiration and that energy is released in the process, students can track the flow of energy and matter through the system of peas in the jar.
Connecting to the Essential Question: What are you supposed to learn today? Have students get out their Cells Unit Plan. Explain that their focus of this particular lesson is Skill 4: I can identify important materials and processes that are required for cells to function.
Have students read the skill and self-assess where they are at with their learning. Students rank themselves on a scale of 1 to 4 4 being mastery. As the unit moves forward, I have the students continually self-assess on each skill.

Check out the student's unit plan below to see how students update their mastery level with each lesson. What is required in an experiment to produce reliable data?
After groups brainstorm, call on each group to share one consideration they came up with and add it as a "light ray" coming off of the light bulb. After going around to each group.
This resource is a representation of what my students typically brainstorm. My students have already been exposed to the scientific method and experimental design criteria.
If there are any important criteria that the students forget, be sure to add it to the graphic organizer on the board. Leave this graphic organizer on the board or chart paper for the remainder of the lesson. What is needed to produce a valid experiment?
Do plants go through cellular respiration? I go through a quick review of the process of cellular respiration by discussing the following questions as a class: What is the purpose of cellular respiration?
Where in the cell does it occur? What are the reactants of the chemical reaction? What are the products of the chemical reaction? Describe what happens to the bonds of the reactants and products and how energy transfers during the process. Then, I explain that one of the products of respiration that the students identified is carbon dioxide.
I explain that when carbon dioxide dissolves in water, it turns into an acid. So, the more CO2 that is formed and contained in a system with water, the more acidic something will be.
I then explain that bromthymol blue is a pH indicator. My students have gone through a unit on chemical reactions including pH so this has a lot of meaning for them. If your students have not, it will warrant an explanation here.
When bromthymol blue is in the presence of a base, it is blue. When it is in the presence of a neutral substance, it is green. When it is in the presence of an acid, it is yellow.Cellular Morphology.
