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. It was predicted that the intensity of light exposure that was given to the Pacific Ocean’s Seaweed, will increase the rate of

In the photosynthesis, carbon dioxide and water yield to glucose and oxygen. Because carbon dioxide and water come from cellular respiration, and it’s made from one molecule of glucose and oxygen. These processes can’t be seen through regular human perfect vision so it is extremely difficult for many to differentiate them that is why experiments are made like the bubbles experiment. These systems are vey important to many animals which are in need of the oxygen that the plants produce. “

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