Use live fish to learn about respiration, dissolved oxygen, and fish. Students will investigate to answer the question:
Does the amount of dissolved oxygen affect the respiration rate in fish?
This investigation meets the *Next Generation Science Standards 3rd-5th Grade Science and Engineering Practices. Students will follow the scientific method to answer the question. Using the pre-reading and their prior knowledge students will write an educated hypothesis. Students will be very excited to use live fish in collecting data on the respiration rate. After the investigation students will calculate the mean, summarize their data, and analyze the results. Follow up reading and questions are included.
Students will love being able to use live fish. Teachers will enjoy watching students investigate and using the teacher and student pages. This is a wonderful way to learn about the effect of oxygen depletion on fish.

*Correlation to the *Next Generation Science Standards
*Background Information and Teacher Tips
*6 Page Investigation Journal
*Follow up Reading and Questions
Goldfish (other fish work too), 1/2 pint mason jar or similar, fish net, 1 minute timer, and water. A pan and stove are needed to prep the water ahead of time.
Using the fish is very easy. I bought my fish on sale for $0.17. After the experiment you can have some classroom pets or give them away.
This lesson is great for classrooms, homeschoolers, scout activities, camps, science fairs, and using for Earth Day.
