Tides in the Hudson
Students view an illustration of the Hudson River watershed and identify the bodies of water shown. They discuss what happens when fresh and salt water mix. Students view a teacher demonstration of the stratification of fresh and salt...
Curated OER
Dissolved Oxygen and Respiration
Students are presented with the question, "Do plants that grow underwater use oxygen?" They create an experiment to test the presence of dissolved oxygen in the water using provided materials. Student experiments include a control jar as...
Curated OER
Temperature
Several slides compare different temperature scales. Thermal expansion, heat transfer, and Maxwell speed distribution are also explored. The last two slides seem unrelated to the topic of heat, but are easily left out of this otherwise...

Don't Be a Square
If Parseltongue is a genetic trait, what is the probability a wizard will inherit the ability to speak Parseltongue? Scholars investigate magical and biological genetics with Punnett squares.
Curated OER
Acid Rain Experiments
Students define the term acid rain, and the causes of acid rain. They locate regions where acid rain is most affected, and what can students deduce from maps of geology and soils in New York State. Students answer the questions why are...
