Assignment: SCIE207 Phase 1 Lab Report

Using the Scientific Method Lab

Establish a better understanding of photosynthesis and cellular respiration, and apply the scientific method to solve (or understand) a problem. Photosynthesis and respiration are reactions that complement each other in the environment. They are essentially the same reactions, but they occur in reverse. During photosynthesis, carbon dioxide and water yield glucose and oxygen. Through the respiration process, glucose and oxygen yield carbon dioxide and water. They work well together because living organisms supply plants with carbon dioxide, which undergoes photosynthesis and produces glucose, and these plants and bacteria give out oxygen, which all living organisms need for respiration.

Assignment: SCIE207 Phase 1 Lab Report

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

• Purpose
  • State the purpose of the lab.
• Introduction
  • 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
  • Ahypothesisis 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
  • Summarize the procedures that you used in the lab. The methods section should also state clearly how data (numbers) were collected during the lab; this will be reported in the results or outcome section.
• Results or Outcome
  • In this section, provide any results or data that were generated while doing the lab procedure.
• Discussion and Analysis
  • In this section, state clearly whether you obtained the expected results and if the outcome was as expected.
  • Note: You can use the lab data to help you discuss the results and what you learned.

Provide references in APA format. This includes a reference list and in-text citations for references used in the introduction section.

Give your paper a title and number, and identify each section as specified above. Although the hypothesis will be a 1-sentence answer, the other sections will need to be paragraphs to adequately explain your experiment.
