Mussel Your Way Through Photosynthesis
Students, using zebra mussels (Dreissena polymorpha), elodea and an indicator dye, observe and record the role of light in photosynthesis. They consider plant production of carbon dioxide and the use of live materials in biological...
Curated OER
Organs to Go...
Students explain the principles of experimental design and reinforce the steps of the scientific method. Each group of students create a "slush" type mixture to store a chicken liver.

University of Colorado: Ph Et Interactive Simulations: Masses & Springs
Hang various mass weights on spring scales while you adjust the spring stiffness and damping in this online activity. Slow down the action, take it to another planet, or watch the amount of potential, thermal, and kinetic energy.
Texas Instruments
Texas Instruments: Beverage Tests
In this activity, students determine the pH of liquid samples. They get familiar with the pH scale, create graphs comparing pH levels, and compare data displayed as a scatter plot, a boxplot, a histogram, and a bar graph.
