CuraÁao
CuraÁao is a computer program that simulates the sterile insect release method (SIRM) of pest population suppression, first conceived by E. F. Knipling (1955).
The user can investigate the effects of several variables on the effectiveness of the method and discover what happens when some of the basic assumptions of the model are relaxed or violated in some way. The user should gain some understanding of the sorts of things that complicate the application of the technique in situations that are
Food Interaction Study
This dataset comes from a study of 8 healthy males randomly assigned to a two-period crossover design, in which they either fasted and then ate, or ate and then fasted. They were given one dose of a drug, blood samples were collected and data on plasma levels were collected. Questions from this study refer to the absorption of the drug. A text file version of the data is found in the relation link.
Counting on Art
In Counting on Art, students will explore the paintings of Horace Pippin and Wayne Thiebaud and the mobiles of Alexander Calder to discover and practice math and visual art concepts.In Pippin's Story, young children (grades K–3) focus on a painting by African American artist Horace Pippin. They will learn how to "read" the clues in a painting and write a story about the work. Students will also solve counting and time problems and create their own "secret number" painting.Calder's Balancing Ac

Grades 6-8.
Chemistry controlling post combustion hydrocarbon oxidation and homogeneous charge compression ignit
Environmental pollution and energy conservation have become of increasing concern over the past few decades. As one of the major sources of energy consumption and urban emissions, automobiles and light trucks (light duty vehicles) are under significant pressure to improve efficiency and reduce exhaust emission levels. While dwindling fuel reserves and greenhouse gas emissions are motivating factors behind long-term interest in increased efficiency, ambient air quality standards and associated pu
Factors influencing meaningful integration of technology into the high school curriculum: a case stu
Technology has significantly impacted American life. Children today grow up with a profusion of electronic wonders. Technology use in schools has lagged behind technological uses in society as a whole. As school districts strive to meet public expectations for technology use, school budgets devote significant dollars to technology related initiatives designed to improve student achievement. While money has been spent on technology, districts struggle to document improvement in student achievemen
Synthesis and characterization of the properties of Ti3SiC2/SiC and Ti3SiC2/TiC composites
In 1996, the ternary compound titanium silicon carbide (Ti3SiC2) was for the first timesynthesized as a single-phase, fully dense compound. Its characterization revealed aunique combination of properties. For its high fracture toughness, low hardness toelastic modulus ratio and excellent damage tolerance, it was dubbed a soft ceramic. Italso displayed good thermal shock and oxidation resistance. In this work, thereinforcement of this material with silicon carbide and titanium carbide particles w
Implications of resource management in La Parguera, Puerto Rico (The)
A recent rezoning of La Parguera, southwest Puerto Rico, as a tourist zone has resulted in an imbalance between development and appropriate resource management. Development associated with tourism is destroying the sub-tropical dry forest and adding pressure on the marine resources through increased boat traffic and marine structures. Declining water quality and benthic community health are two of the impacts seen in La Parguera associated with these land use changes. This study is three-fold. F
AP Environmental Science
Welcome to the NROC Advanced Placement (AP) Environmental Science course. This curriculum covers all of the material outlined by the College Board as necessary to prepare students to pass the AP Environmental Science exam. This course is designed to acquaint you with the physical, ecological, social, and political principles of environmental science. The scientific method is used to analyze and understand the inter-relationships between humans and the natural environment. The course shows how ec
Measurable You!
This lesson introduces an anthropometric measurement system developed to identify and track people in the penal system in late 19th and early 20th century. Students conduct a guided experiment and discussions while collecting anthropometric measurements, exploring the impact of experimental errors in a scientific system, and explaining their observations/findings in writing.
One Nation: Two Futures?
Since the mid-l970s, economic reforms have transformed China from one of the most egalitarian societies into one of the most unequal in the world. Wide disparities currently exist between the income levels of a relatively few rich and middle-class Chinese and their fellow citizens who number in the hundreds of millions. This "wealth gap" is particularly acute when one compares the incomes of urban and rural residents, between Chinese living in the interior of the country and those living in the
Treats in a Basket
Students develop intuitive understandings about the probability of landing on particular board spaces when a die is rolled. They analyze the probability of multiple rolls by making outcome tables, trees, etc.
Treats in a Basket is designed to encourage students to experiment with probability. It will motivate students to learn about the subject in order win the most treats. It should be played by students who are already comfortable with fractions. Students should also be familiar with calculat
CK-12 Geometry (CA Textbook)
CK-12's Geometry delivers a full course of study in the mathematics of shape and space for the high school student, relating the ancient logic and modern applications of measurement and description to its essential elements, processes of reasoning and proof, parallel and perpendicular lines, congruence and similarity, relationships within triangles and among quadrilaterals, trigonometry of right triangles, circles, perimeter, area, surface area, volume, and geometric transformations.

The activities focus primarily on physical and earth science content, geography, and inquiry skills. Assessments and scoring rubrics, including a pre-assessment that can be used for both modules, are embedded in each module, providing opportunities for tracking student learning. The Antarctic Exploration module is framed by Sir Ernest
EngineSim and RangeGames Downloads
EngineSim was developed at the NASA Glenn Research Center in an effort to foster hands-on, inquiry-based learning in science and math. EngineSim is a simulator that models the design and testing of jet engines. The program works in two modes: Design Mode or Tunnel Test Mode. In the Design Mode, you can change design variables including the flight conditions, the engine size, the inlet performance, the turbo machinery compressor and turbine performance, the combustors or burner performance, or th
