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:
