Pasco Optical Dissolved Oxygen Sensor

Use this dissolved oxygen sensor for water quality, photosynthesis, respiration and other experiments in aqueous solutions.

The Basics

These resources may be for a newer model of the sensors we offer. The function should be the same if not similar to what we offer.

Standards Connections

These resources can be used to support standards-based teaching and learning.  They are not intended to meet the full scope of any given standard.  Only some standards are highlighted; many more standards may be connected!  We encourage you to explore and to let us know if you have any questions!

MS-LS1-7. Develop a model to describe how food is rearranged through chemical reactions forming new molecules that support growth and/or release energy as this matter moves through an organism. 
HS-LS1-7. Use a model to illustrate that cellular respiration is a chemical process whereby the bonds of food molecules and oxygen molecules are broken and the bonds in new compounds are formed, resulting in a net transfer of energy.
HS-LS2-3. Construct and revise an explanation based on evidence for the cycling of matter and flow of energy in aerobic and anaerobic conditions.
HS-LS2-4. Use mathematical representations to support claims for the cycling of matter and flow of energy among organisms in an ecosystem. 
HS-LS2-5. Develop a model to illustrate the role of photosynthesis and cellular respiration in the cycling of carbon among the biosphere, atmosphere, hydrosphere, and geosphere.
