Water Ecology Lab
Students determine the characteristics of a stream ecosystem and its organisms. In this water ecology lesson students complete several labs that shows them presence of life, water appearance, and water flow.
Curated OER
Where in the World is Carbon Dixoide?
Students conduct experiments designed to detect the presence of CO2 by using a BTB that changes color (blue to yellow) in the presence of CO2. First, students experiment with the CO2 from combining vinegar and baking soda. In part two,...
