Land Cover Change Detection Protocol
The purpose of the resource is to investigate changes in the major land cover types of Study Sites by examining Landsat satellite images acquired years apart.
The purpose of this resource is to become familiar with the hydrology of your locale. Students will study and visit the Hydrology Study Site, conduct a visual survey to discover information about local land cover, water quality, and document their findings. They will use this initial investigation to raise questions about local land cover and/or water chemistry issues that may require further investigation.
WeatherHawk Weather Station Protocol
This resource provides instructions on how to log atmosphere data using a WeatherHawk weather station. A weather station is setup to measure and record atmospheric measurements at 15-minute intervals and can be transferred to the GLOBE program via email. Students can view data for their school that are continuous and show variations within a day. The data collected includes wind speed and direction and pressure thereby supporting a more complete study of meteorology using GLOBE. Students pursue
Water Transparency Protocol
The purpose of this resource is to determine the transparency of water. Students measure water transparency at their undisturbed study site using a transparency tube or Secchi disk.

Exponential Numbers - Grade 11
In Grade 10 we studied exponential numbers and learnt that there were six laws that made working with exponential numbers easier. There is one law that we did not study in Grade 10. This will be described here.
Extreme Global Makeover
Modernization is an important issue in the New York State Global History and Geography curriculum. Students are expected to understand how modernization may impact such areas as society, politics, the economy, and the environment. In the Global History and Geography curriculum, a study of historical examples of modernization includes examples of attempts to transform society, such as the Meiji Restoration or Kemal Ataturk. In this lesson, two PBS WIDE ANGLE documentaries -- "To Have and Have Not
Student-authored multimedia tutorials that cover a variety of study skills topics (e.g., time management, essay writing, note-taking, textbook reading)
Understanding a bedload-dominated stream through spreadsheet modeling
The purpose of this lab exercise is to teach students to "think like a stream" by integrating modeling with field data to understand the nature of adjustments in bedload-dominated fluvial systems through the study of a piedmont alluvial stream and its deposits. This is a computer-based lab activity ...
Water Quality Acquisition
In this activity, students visit two sites to practice their field water sample collection and water quality assessment skills. They use a vertical well-water sampler and downhole water quality probes to measure groundwater conductivity, pH, and temperature at different depths in a landfill. Collected water conductivity data is contoured to map the distribution of a contaminant plume. Students then study acid mine drainage by using water quality meters to compare pH and conductivity values up an
Sustainable Development for Engineers
By independent study of the book Sustainable Development for Engineers (K.F. Mulder, 2006) students acquire basic knowledge about sustainable development
"[T]ests have shown . . . that our three average men are equal."
By the mid-twentieth century, the movement of African Americans from farms to cities, along with their participation in World War II industries and union organizing, spawned the origins of the modern civil rights movement. Although conflict between white and black workers continued, many African Americans ...
Mating preference in the commercially imported bumblebee species Bombus terrestris in Britain (Hymen
Commercial trade of bumblebees in Europe results in different subspecies of Bombus terrestris being shipped into regions where they are not native. Although previous studies have shown that these subspecies will interbreed, none have assessed mating preference of the different populations. This study examines the mating preferences between two geographically isolated populations of B. terrestris which have unnaturally been brought together through the commercial trade in bumblebees. Under contr
This Flash based applet simulates data from a case study of treatments for tumor growth in mice. This simulation allows the user to place mice into a control and treatment groups.
Sea Urchin Development
This article describes set-up and maintenance of marine aquaria for maintaining sea urchins and procedures for the study of developmental biology of sea urchins from fertilization to pluteus larva.
The Power of Genetics: Using Classical and Molecular Genetics to Study "Real" Developmental Phenomen
The goal of this laboratory exercise is to provide a laboratory experience for undergraduates, in which they apply fundamental genetic principles to the study of a complex developmental process, specifically, root cell shape determination in the simple plant Arabidopsis thaliana. In this exercise, students identify putative root cell shape mutants, analyze an F2 segregating population, and finally use molecular techniques to determine where a specific mutation in located within the genome. This
Using Bromelain in Pineapple Juice to Investigate Enzyme Function
This investigation introduces students to the structure and function of the proteolytic enzyme, bromelain, which is present in large quantities in the fruit, leaves, and stems of pineapple. In this lab exercise, students study the rate at which bromelain catalyzes the hydrolysis of gelatin (substrate) at different temperatures and pHs. Strips of developed black and white photographic film are placed in freshly squeezed pineapple juice under different experimental conditions. The time it takes fo
Using Handheld Wireless Computers to Increase Interactivity and Collaborative Learning in Large Clas
We conducted a pilot study to determine the effectiveness of wireless, handheld computers in fostering active and collaborative learning in lecture-based teaching. We compared the capabilities of the largest type of handheld, the Jornada 820, to that of the smallest, a Handspring Visor "personal digital assistant." This article describes our use of the handhelds in a variety of classroom exercises, emphasizing wireless internet access. We explain our successes, problems, and proposed solutions.
Were Dinosaurs Cold- or Warm-Blooded?: An Exercise in Scientific Inference
Both metabolic rates and brain masses are approximately 10 times as great in modern terrestrial warm-blooded animals (birds and mammals) as in cold-blooded terrestrial animals (reptiles) of the same body mass. This is one of several lines of evidence scientists have used to infer the mode of thermal regulation of dinosaurs and other extinct amniotes. In this exercise each student is assigned one of a number of dinosaurs. Students estimate brain mass from a drawing of a cranial endocast and body
