Science Buddies: I'm Trying to Breathe Here! Dissolved Oxygen vs. Temperature
To survive, we need oxygen in the air we breathe. Oxygen is also essential for most aquatic organisms, but there is much less oxygen available in water than in air. Learn how to measure dissolved oxygen and then see how oxygen...

Texas Instruments: Dissolved Oxygen
Students use the Dissolved Oxygen Probe to measure the concentration of dissolved oxygen in water from streams and rivers. They correlate the availability of dissolved oxygen to temperature, pressure, and salinity.

Science Buddies: Harmful Algal Blooms in the Chesapeake Bay
Harmful algal blooms occur when algae, which form the base of the ocean food web, grow in massive numbers and produce toxic or harmful effects on people, fish, shellfish, marine mammals, and birds. In this project you will learn how to...
