Japanese Ant Image Database
The 2003 revised edition of the Japanese Ant Image Database was developed under the direction of the Japanese Ant Database Group (JADG). The website, which merges taxonomic information and stunning photographs, will no doubt delight myrmecologists and others. Information about different types of ants can be accessed through browseable, hyperlinked lists organized by subfamily, genus, and species. Genus and species profiles include images, references, descriptive information, simple distribution
systems of linear equations
Solve a system of linear equations by graphing and finding the intersection of the lines of the equations. Create a system of equations, examine its graph, matrix, and table of values, and determine the solution of the system.
Compound Independent Events
Compare the theoretical and experimental probabilities of compound independent events by drawing colored marbles from a bag. Record the results of successive draws with or without replacement of marbles to calculate the experimental probability.
The secret life of the brain
This web site was developed to accompany the PBS television series The Secret Life of the Brain, which explores how the human brain develops and changes from infancy through late adulthood. Among the site's features are a timeline of human knowledge of the brain, an interactive three-dimensional brain model, and illustrated descriptions of various brain scanning techniques. There are also sections devoted to each episode of the TV series that provide an overview of the episode, brief video clips
LEARN was created to increase middle school science teacher knowledge of and interest in the atmospheric sciences. The original project began in 1991 with funding from the National Science Foundation (NSF). Much of the instructional and science content foundation for the LEARN workshops came from the teaching modules developed by LEARN teachers in collaboration with more than 60 National Center for Atmospheric Research (NCAR) scientists. The modules (Ozone in Our Atmosphere, Atmospheric Dynamics
Science Sampler : Hypothesis-based learning
Are visions of students hypothesizing, designing experiments to test their explanations, analyzing data, writing formal publications of results, and debating over scientific procedures in an attempt to justify their control of variables dancing in your head? This dream can become a reality when you implement hypothesis-based learning (HBL) into your science curriculum. Follow the suggestions found in this article to put your dream in motion, and wake-up to a classroom teeming with motivated, on-
All About Sea Ice
Launched by the National Snow and Ice Data Center, the All About Sea Ice website is designed as an introduction to sea ice: what it is, how it forms, how it is studied, how it affected historical expeditions in the polar regions, and what role it plays in the global climate. The site contains over 80 pages of information on sea ice, including a glossary of sea ice terms and links to more information. The primary focus of the site is as a resource for the general public, educators and students in
This informational piece, part of a series about the future of energy, introduces students to a four-stage process for reading material online. The process includes getting started, reading, rereading and reviewing, and finishing. Each stage comes with a student tip sheet to enable students to work through the processes in a step-by-step manner. Students examine, summarize, review, and then use their new information. A graphic organizer provides students with an opportunity to evaluate the infor
National Oceanic and Atmospheric Administration : Climate Homepage
This National Oceanic and Atmospheric Administration website provides climate information and data. This site offers a variety of product links to climate monitoring, climate at a glance data, U.S. drought assessment, global climate change information, weather observation stations and more. Users can also link to organizations which participate in climate research such as the National Climate Data Center, Ocean Climate Laboratory and the National Weather service. This site is an excellent resour
Box plot (grades 6-8)
This virtual manipulative enables students to construct box plots to summarize data. Students enter data into a table, and the manipulative displays the minimum and maximum data values, the lower and upper quartiles, and the median. The number in the data set, the average, and the standard deviation are also shown. In addition, the manipulative allows users to order the data. Instructions for using the manipulative, suggestions for classroom use, and a link to the standard for data analysis and
Valley Springs Snow Cream
Middle School, difficulty level 2. Compare the volume of a sphere, cone, and cylinder using ice cream.
Cups and Volume
How can I calculate the volume of a box, if I know how many cups of rice fill it? And how can 2 cups be a volume measure?
Scope on Safety : What Is Your First Aid Policy?
Would you know what to do if one of your students had an accident with a chemical that resulted in contact with the skin? What would you do if a student spilled boiling water on his or her hands? These are the types of potential challenges science teachers face every time they walk into a laboratory with students. Prepare yourself for the worst case scenario by developing a first-aid policy for your science classroom as outlined by the Occupational Safety and Health Administration Regulations (O
Appendix 2 Acronyms
Optical-fibre communications became commercially viable in the 1970s and innovation continues today. This unit will illustrate how very high data rates can be transmitted over long distances through optical fibres. You will learn how these fibres are linked, examine the technology used and assess the future direction of this continually developing area of communication.
Introducción al Derecho (2011)
Esta asignatura se configura dentro del Primer Curso del Grado en Relaciones Laborales de la Universidad de Cantabria, teniendo como finalidad, la asimilación de conceptos jurídicos básicos. A tal efecto, se efectúa una aproximación a la idea de Derecho; se estudia la norma jurídica; las fuentes del Derecho; el Estado y sus instituciones básicas; y los derechos fundamentales.
Food Chains and Food Webs - Balance within Natural Systems
This lesson, supported by the provided power point lecture ( LESSON 1 and 2 Ecology Lecture Supplement ), introduces students to the concepts of food chains and food webs. Through its use, students learn the difference between producers and consumers and study how these organisms function within their communities to interact in various food chains. Multiple food chains link together to form intricate and balanced food webs. Focus continues to rest on the Sonoran Desert. At the conclusion of this
Digital Mapping and Geographic Information Systems (GIS)
Geographic Information Systems (GIS), once used predominantly by experts in cartography and computer programming, have become more and more pervasive in both business and consumer use. This unit explores GIS in general as a technology for about which more can be learned, and it also explores applications of that technology. Students will especially get to experience GIS technology through the use of Google Earth on the environmental topic of plastics in the ocean in an area known as the Great Pa
Students are introduced to chemical engineering and learn about its many different applications. They are provided with a basic introduction to matter and its different properties and states. An associated hands-on activity gives students a chance to test their knowledge of the states of matter and how to make observations using their five senses: touch, smell, sound, sight and taste.
Physics of Roller Coasters
Students explore the physics utilized by engineers in designing today’s roller coasters, including potential and kinetic energy, friction, and gravity. First, students learn that all true roller coasters are completely driven by the force of gravity and that the conversion between potential and kinetic energy is essential to all roller coasters. Second, they also consider the role of friction in slowing down cars in roller coasters. Finally, they examine the acceleration of roller coaster cars
