Title: Understanding the Scientific Method: Photosynthesis and Cellular Respiration

Instructions: Based on the virtual experiment, you will answer some questions and write a 1-page lab report using the scientific method.

When your lab report is complete, submit this document to your instructor in your assignment box.

Using what you learned on the lab animation, answer the following questions:

• Define a hypothesis that is suggested by the data that are collected in the lab.

• Complete a lab report using the scientific method.

• What effect does the intensity of light have on the rate of photosynthesis (measured as the number of oxygen bubbles)?

• Is it possible to examine the relationship between photosynthesis and cellular respiration under controlled experimental conditions? Explain your answer in detail.

Part 1: Using the lab animation, fill in the following data tables to help you generate your hypothesis, outcomes, and analysis:

Table 1: Rate of Photosynthesis Measured by the Number of Oxygen Bubbles

Light Bulb Trial 1 Trial 2 Trial 3 Average

0 watts 2 1 3 2

25 watts 7 4 4 5

50 watts 11 11 11 11

100 watts 12 13 12 12

Part 2: Write a 1-page lab report using the following sections of the scientific method:

• Purpose

o State the purpose of the lab.

• Introduction

o This is an investigation of what is currently known about the question that is being asked. Use background information from credible references to write a short summary about the concepts in the lab. List and cite references in APA style.

• Hypothesis or Predicted Outcome

o A hypothesis is an educated guess. Based on what you have learned and written about in the introduction, state what you expect to be the results of the lab procedures.

• Methods

o Summarize the procedures that you used in the lab. The methods section should also state clearly how data...
