Curated OER
The Effects of Temperature Variations on the Heartbeat Rate of Daphnia
Young scholars use DigiScope technology to investigate Daphinia, popularly known as water fleas. They design, conduct, and report on an experiment to determine the effects of varying water temperatures on the heartbeat rate of Daphnia.
Curated OER
Teaching about the Effect of Photosynthesis and
Students demonstrate the effects of photosynthesis and respiration. They decide which variables to analyze in a microcosm study. They produce a written paper, oral presentation, poster, or multi-media presentation
Curated OER
Earth Materials Module
This slide show progresses through a comprehensive review of the grounding principles of earth science. Get down and dirty with the details of fossil fuels! Help your geologists to have a rock solid understanding of the rock cycle. The...

Six Pack Loop Rings Photodegradable?
Students review experiments testing the photo degradability of the six-pack plastic ring and complete further experiments on the process.
Curated OER
Diffusion through Membranes
Students identify diffusion and its processes through experimentation and calculations. They also use a CBL and conductivity probe to measure the conductivity of various solutions and study the effect of concentration gradients on the...

Are Polymers Photodegradable?
Students study the term photodegradability and how it applies to the 6-pack loop ring. For this materials lesson students test photodegradability of the 6-pack plastic ring.
National Geographic
National Geographic: Human Impacts on Marine Species
Students learn about three examples of human impacts on marine life: migration patterns and shipping, algal blooms and water chemistry, and marine debris. Some of these impacts are due to human activity in the ocean, and some impacts on...
NASA
Nasa: The Basics of Ocean Chemistry: Carbon, Circulation, and Critters
An explanation of ocean chemistry, supported by illustrations, for example, of the global carbon cycle in the 1980s and the annual carbon dioxide flux. The concentration of nutrients in the ocean is discussed for its impact on marine...
Texas Instruments
Texas Instruments: P H
Students use a pH sensor to measure the pH level of water in a stream or lake. They examine how air pollutants like sulphur dioxide, nitrogen oxides, and carbon dioxide cause acid rain, which affects the pH of water bodies and aquatic...
