Reflection: Developing a Conceptual Understanding Photosynthesis and Cellular Respiration - Section 4: Elaborate


The goal for this lesson was to help students to learn more details about two equations that they learned about in Biology class.

This movie explains my overall goal for the lesson.

Through analysis of students' answers to the final question on the worksheet, "Explain the similarities and differences of Photosynthesis and Cellular Respiration" I feel that students took away that the processes are basically opposites of each other as well as the fact that energy plays a major part of the equations. 

Here are some examples of students responses.  Note how they all talk about similarities and differences but are done at different levels.

In example 2 the student compares the process by simply referring to energy.  In  example 3 the student also talks about the reactants and products along with energy.  In example 4 the student elaborates quite a bit on the similarities and differences and uses a chart to compare the two.  Finally in example 5 the student uses high-level language to compare the processes.

Photosynthesis and Cellular Respiration

Unit 5: Unit 6: Energy
Lesson 5 of 9

Objective: Student will be able to model and differentiate the processes of photosynthesis and cellular respiration through watching computer simulations and answering questions.

Big Idea: Photosynthesis transforms light energy into stored chemical energy while respiration uses the bonds of stored energy to make new bonds through the transfer of energy.
