Dr. Saul's Biology in Motion
This site offers an interactive simulation activity, which examines how natural selection works to bring about the evolution of adaptations. Using the simulation tool, the student can slow down the process to watch all the steps involved or can speed it up to watch how a population evolves over time. Links are provided to a variety of useful sites.
Observe common objects made of minerals
This interactive Earth science resource lets students first see six images of minerals and then, by placing their cursor over each image, an image of an everyday object made from that mineral. Quartz, gypsum, and fluorite are among the minerals shown, with the corresponding familiar objects being glass, drywall (Sheetrock), and toothpaste. Copyright 2005 Eisenhower National Clearinghouse
This video clip, viewable in RealPlayer, introduces students to the research that Maryland biologists are conducting to assess the status of bat populations in their state. Technologies are discussed that help scientists study the often elusive bats. The clip shows that when researchers descend into a cave to survey the number of hibernating bats there, they discover fewer bats are present than in previous years. The clip also notes that efforts to conserve bat populations are needed. Bats contr
Ready, Set, Escape
During this project, students will be asked to design a device that will measure out a time period of exactly 3 minutes. They will be asked to brainstorm ideas using the different materials provided. Students will observe and explain the effects of conservation of energy.
Blue Planet Challenge - A natural history of the oceans
This very interactive site uses a variety of games to explore ocean related subjects. The games cover such topics as tidal zones, deep ocean species, ocean currents, general animal life of the ocean, symbiotic relationships, water pressure, human impact on ecosystems, and the habitats found at the South Pole and along the California coastline. There are help tabs added to the games called Species Fact Files and Infobursts where a player can find out more information on a particular topic if need
JGI Nitrosomonas europaea ATcC 19718
As part of the DOE initiative to explore the role of microorganisms in global carbon sequestration, the Joint Genome Institute is sequencing the autotrophic nitrifying bacterium Nitrosomonas europaea. This organism plays a central role in the availability of nitrogen to plants and hence in limiting C02 fixation. These bacteria are important players in the treatment of industrial and sewage waste in the first step of oxidizing ammonia to nitrate.
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
Science Education Gateway (SEGway)
This is an opening page and index for Science Education Gateway (SEGway), which helps teachers create science lessons for grades K-12. There are links to categories such as Space Science, Sun Earth, Solar System, Lesson List, and NASA. The site also provides links to science movies, games, and quizzes; tools and guidelines for lesson development; hands-on learning projects; and suggested inquiries and investigations. The web site is presented by the Center for Science Education (CSE) at Space Sc
Explore more news WebQuest, short term
This teacher resource, part of a series on the future of energy, contains a webquest activity where students work as newspaper reporters and write articles. Webquests are inquiry-oriented activities that use the Internet. To complete this activity students examine the Explore More! energy site and write a newspaper article from the viewpoint of a human interest story, an issue report, or general news article. The activity sheets provide an introduction, detail the task, suggest steps to follow,
Observe how glaciers erode bedrock surfaces
In this interactive Earth science resource, students are first presented with six different photographs showcasing how glaciers can erode bedrock. Students are instructed to click on each labeled image to see an enlarged version of it. In the enlarged view, each photo is accompanied by a sentence or two that explains the glacial erosion shown. The images include features such as cirques, medial moraines, and striated bedrock. Copyright 2005 Eisenhower National Clearinghouse
Valley Springs Snow Cream
Middle School, difficulty level 2. Compare the volume of a sphere, cone, and cylinder using ice cream.
Science Sampler : Fossil detectives
Middle school students are transformed into Fossil detectives as they examine the fossil record and use evidence about paleo-environments to develop an understanding of structure and function in living systems and changes over time in Earths history. In this enrichment activity, students work in teams to research an assigned geologic time period. They determine available habitats, food sources and types (animal, plant; woody, herbaceous, etc.), cover sources, methods of getting food, defense, an
This site presents seven lessons that allow students in grades K-3 to investigate the concepts of understanding and reading maps. The lessons utilize a story about a little girl named Nikki who visits an imaginary amusement park. A teacher guide for each lesson includes objectives, teaching suggestions, activities, and student worksheets.
Scope on Safety : Collaborating safely
With the advent of inclusion legislation such as the Individuals with Disabilities Education Act (IDEA) or PL 105-17 Reauthorization Action of 1997, many schools have focused on teaching partnerships between regular education and special education teachers. Science departments have been no exception to the trend toward team-teaching. This article describes five of the most popular models of team teaching. In addition, the legal implications and science safety issues concerning collaboration are
King Leads the March on Washington
the March on Washington (3:10) On August 28, 1963, a quarter million people gather to support civil rights, and share Dr. King's "dream" of equality. This video is highlighted by King's "I have a dream speech" and the reaction to it. The efforts of the federal government to enforce civil rights is explained as well as how the March was organized and where.
Visible Light and the Electromagnetic Spectrum
In this lesson, the electromagnetic spectrum is explained and students learn that visible light makes up only a portion of this wide spectrum. Students also learn that engineers use electromagnetic waves for many different applications.
Energy in our Lives Carousel
This activity is way for students to discover that they already know a lot about energy through their own life experiences. They are active consumers of various forms of energy and are aware of energy purchases for transportation, electricity and (possibly) home heating. A pedagogical technique of a “carousel” is used to get all students involved in brainstorming and contributing ideas. The goal is to introduce students to some key terms and issues associated with energy as a necessary prere
Thrown for a Loop
In this lesson, students begin to focus on the torque associated with a current carrying loop in a magnetic field. Students are prompted with example problems and use diagrams to visualize the vector product. In addition, students learn to calculate the energy of this loop in the magnetic field. Several example problems are included and completed as a class. A homework assignment is also attached as a means of student assessment.
Students are introduced to the circulatory system, the heart, and blood flow in the human body. Through guided pre-reading, during-reading and post-reading activities, students learn about the circulatory system’s parts, functions and disorders, as well as engineering medical solutions. By cultivating literacy practices as presented in this lesson, students can improve their scientific and technological literacy.
Engineering Your Own Spectrograph
Students use simple materials to design an open spectrograph so they can calculate the angle light is bent when it passes through a holographic diffraction grating. A holographic diffraction grating acts like a prism, showing the visual components of light. After finding the desired angles, students use what they have learned to design their own spectrograph enclosure.
