- Students will investigate and discover relationships among dissolved oxygen levels, pH, and temperature.
- Students will manipulate the levels of temperature and pH to determine the effects on dissolved oxygen, population and species richness in a freshwater system.
- dissolved oxygen
About the Lesson
In this lesson, students will:
- Understand how the temperature of the water affects the dissolved oxygen levels.
