Fibers, Dyes, and the Environment
Nanofibers can be made through electrospinning or force spinning in order to reduce the negative impact on the environment. Pupils study the role of fibers and dye on the environment through a series of five hands-on activities. Then,...
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...

Documenting Science Through an Active Inquiry Process
Students follow procedures regarding scientific data collection. In this scientific inquiry lesson, students investigate inquiry questions through research and data collection. Students use technology tools to create products that...

Do Human Practices Affect Water Quality?
Students determine if human practices have any noticeable effects on the quality of stream life as measured by the presence of certain macroinvertebrates. They collect, preserve and identify macroinvertibrate samples and quantify the data.
Curated OER
Off Base
Young scholars explain the Chatelier's Principle. In this pH lesson, students identify factors that resist changes in pH of the ocean and why the ocean is becoming more acidic.

Investigate Pine Creek!
Students are invited to become detectives in this Web-Integrated Science Environment (WISE) as they explore a local creek, its environment and ongoing status. Students participate in field trips, acquisition of data through water testing...
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,...
Science 4 Inquiry
The Ups and Downs of Populations
As the reality of population decline across many species becomes real, pupils learn about the variables related to changes in populations. They complete a simulation of population changes and graph the results, then discuss limiting...
Curated OER
Car Wash
Students determine the most appropriate site for a car wash, based on each site's soil characteristics (chemical, physical) and topographic features. They perform an experiment to determine the changes to three different soil types when...
Curated OER
Analyzing the Relationship between Snowpack and River Flow
Learners use the Internet to research current and past snowpack levels and river gauging station readings. They determine the relationship between snowpack and river flow. They predict future river flow.
Curated OER
Water Regulation
Students use their basic knowledge of physiology to analyze graphical data of paramecia under diverse conditions. From the data analysis, Students develop explanations of the animal's response to the concentration of different solutions...
Curated OER
Designing an Underwater Habitat for Humans
Students consider the limitations of deep water oceanography and design an underwater habitat to support scientists while they complete long term studies under the ocean. For this engineering lesson, students are introduced to the...
Curated OER
Off Base
Students study La Chatelier's principle and identify how carbon dioxide may affect pH. In this coral lesson students complete a worksheet on pH and observe a lab.
Curated OER
Wastewater
Students discuss what happens to their wastewater. They read about the wastewater treatment process. Students are asked what types of things get flushed down toilets or goes down drains in sinks and showers. They are taught what happens...
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.

Methane Hydrates – What's the Big Deal?
Have you ever tried to light ice on fire? With methane hydrate, you can do exactly that. The ice forms with methane inside so it looks like ice, but is able to burn. The lesson uses group research and a hands-on activity to help scholars...

Lab 2: Nanocatalysts Clean Your Car Emissions
Surface area certainly surfaces as a variable for chemical reaction rates. Scholars perform an experiment to discover how the size of catalysts affect the rate of a chemical reaction. They record their results in tables and graphs to...
Curated OER
Walking Magic
Young scholars investigate surface tension using water striders. In this inquiry lesson, students develop a researchable question about the topic. They explain the environmental consequences of lowering water surface tension.
Curated OER
The Captain And Lake Wilmar
Tenth graders examine the ecosystem of Lake Wilmar through three coordinated performance tasks. They first investigate the effects of pH on freshwater animals by comparing the zooplankton counts from three different areas. They then...

How Effective is Perspiration at Cooling?
High schoolers collect data on the cooling of water in two different test tubes, one that is wrapped in wet newspaper and one in dry newspaper. They then relate this cooling effect to the body's perspiration.
Curated OER
Hydrated Salt
Students plan, design, and carry out an experiment to determine an empirical formula for a hydrated salt X that tell students when all the water has been removed from hydrate crystals.
Curated OER
Introduction to Toxicology
Students explore the science of toxicology and the relationship between a toxic reaction (response) and amount of substance (dose). They observe two demonstrations illustrating the concept of dose-response.
