Recommended

Interdependence of Plants and Animals

Experiment #14 from Biology with Vernier

In this experiment, you will

  • Use a Dissolved Oxygen Probe to measure the dissolved oxygen in water.
  • Use a pH Sensor to measure the pH of water.
  • Use pH measurements to make inferences about the amount of CO2 dissolved in water.
  • Determine whether snails consume or produce oxygen and CO2 in water.
  • Determine whether plants consume or produce oxygen and CO2 in the light.
  • Determine whether plants consume or produce oxygen and CO2 in the dark.

Inquiry

Decomposition Column Investigations

Experiment #18 from Investigating Environmental Science through Inquiry

In the Preliminary Activity, you will gain experience using a pH Sensor and learn pH measuring technique as you determine the pH of a water sample.

After completing the Preliminary Activity, you will first use reference sources to find out more about the decomposition and related concepts before you choose and investigate a researchable question.
