The Chemistry of Hair Care
Students do hands-on activities and read information online in order to answer the central question of this lesson: How does understanding the chemistry of hair care, including the role of pH, help in the development of better hair-care...
Curated OER
Investigating the Soil
Students explore the Earth's crust by researching pH levels and acidity. In this environmental safety lesson, students identify the pros and cons of acidity within soil and how it affects plants. Students collaborate in a pH level...
Curated OER
Can Chromatography Separate A Pigment?
High schoolers separate a mixture of pigments with ion exchange chromatography and predict whether the ion-exchange matrix is positively or negatively charged based on the type of pigment bonded to the matrix.

The Effects of Environment on Plant Growth: Selecting Seeds for Survival on a New Planet
Fifth graders conduct experiments to compare seed germination and plant growth rates. They construct a hydroponic plant unit and a lighthouse. They care for the plants for a month and collect data for graphs. They write a report.
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
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
Change Since 1609
Students recognize how the climate of the Hudson Valley has changed since the last glaciation. They explain these changes using a reconstruction of the land use changes in the Hudson Valley composed of confetti, Ziploc bags and other...
Curated OER
Paleoclimate of the Hudson Valley
Students recognize how the climate of the Hudson Valley has changed since the last glaciation and be able to explain these changes. They reconstruct the paleoclimate of the Hudson Valley.

A Tour Down the Hudson River
Students discuss how the Hudson River is an ecosystem made up of both biotic and abiotic factors. They view the PowerPoint the Journal Down the Hudson River. Students become aware of where the Hudson River begins and ends, the plant and...
Curated OER
Dissolved Oxygen and Temperature
Students are shown how temperature affects dissolved oxygen and they create a graph showing this relationship. They think about the adaptations of animals to live in different water temperatures. Students test four different water...
Curated OER
Dissolved Oxygen Introduction
High schoolers are shown how dissolved oxygen enters the water. They are taught the difference between a water sample that has been exposed to the air and one that has not. Students brainstorm what organisms need to survive. They use...
Curated OER
Is Our Water Healthy?
Students test water for a least one chemical characteristic. They hypothesize how a storm event might change the chemical characteristics of a stream. Students collect water samples and use the chemical test to test the water.
