Observe an animation of metamorphic rocks forming
This interactive Earth science resource for middle and high school students demonstrates how heat and pressure beneath the surface of the Earth change igneous rocks into metamorphic rocks. Photographs accompanied by a short animation and text boxes illustrate how the igneous rock diorite is transformed into the foliated metamorphic rock gneiss. The mineral components of each rock are labeled. Students are able to use control buttons to play, pause, and move forward and backward through the simul

Barbie bungee
In this lesson, students model a bungee jump for a Barbie doll. They collect data in a table (number of rubber bands and jump distance), then create a scatterplot of the data, find its line of best fit, and write an equation of that line. Students go on to analyze the equation, noting its slope in relation to the data collected, and the meaning of the y-intercept. Since the distance to which the doll will fall is directly proportional to the number of rubber bands, the lesson provides a scenario

Microbes : too smart for antibiotics?
This lesson packet builds on a peer-reviewed article about antibiotic resistance in microorganisms. The packet contains discussion questions about the article, instructions for an activity about hand washing that uses fake, fluorescent 'germs,' and two handouts of ideas for student activities. The first handout is appropriate for general biology students, and the second is designed for advanced, AP, or first-year undergraduate students. In many of the activities, students create a product, such

The Need for Ocean Literacy in the Classroom - Part I : An overview of efforts to promote ocean lite
Society is largely ocean illiterate and a basic understanding of the key concepts needed for sound decision making on matters related to sustainability and the health of humankind is lacking. At present, a network of approximately 100 members of the ocean science and education communities are working together to make understanding the ocean part of the formal K-12 curriculum. The emergent consensus among the members of the group has resulted in a definition of ocean literacy that is supported by

Shape explorer
This Java applet is designed to allow students to practice visualizing and calculating area and perimeter for figures formed by adjacent squares on a grid. After the student selects a size using a slide bar, the Java applet generates a random closed figure. The student enters values for the figure's area and perimeter, which are checked automatically. The applet limits figures to rectangles and generates two column comparisons of areas and perimeters for multiple figures. From the activity page,

Lotto or Life: What Are the Chances?
Students are naturally inquisitive about space science and the topics surrounding the existence of intelligent life in other parts of our Universe. Tapping into this curiosity, this lesson uniquely combines the concepts of astronomy and probability to have students use inquiry, problem solving, reasoning, and communication skills to compare winning the lottery with the likelihood of intelligent life existing elsewhere in the Universe. The site contains all of the information and materials needed

Zookeeper
Teachers can direct students to this material to help them investigate a career as a zookeeper. Having students review this page can be an excellent precursor to a job-shadowing activity. The discussion board's set of questions and answers can be a helpful resource for an activity in which students produce a number of pertinent questions that should be asked of a zookeeper when investigating this field of work.

Powerhouse
Which dam is the largest hydroelectric producer in the United States? This article, part of a series about the future of energy, introduces students to the Grand Coulee Dam. Students read about the amount of concrete needed to build the dam, the number of dams on the Columbia River, and Lake Roosevelt. The article includes information about the power facilities located at the dam and a photograph of the dam face. Copyright 2005 Eisenhower National Clearinghouse

Teacher's guide to the infrared
This is a page from a larger website, Seeing our World Through a Different Light, sponsored in part by NASA. This page contains side by side standard and IR photos to illustrate how IR photos show heat. It describes and compares visible light and infrared light. An explanation, accompanied by photos, of how infrared cameras work is also provided.

POP Goes Antarctica?
As students explore this Web site, they will learn how scientists work together to answer questions. This site follows several scientists to Antarctica where they are doing research on Persistent Organic Pollutants. A daily journal, glossary, and learning activities will help incorporate this into classroom lesson plans.

What is sugar?
This reading, part of a site about the science of cooking, provides general scientific information about sucrose (white table sugar) together with explanations of the science behind some candy-making procedures. The general information includes the chemical formula of sucrose and a ball-and-stick model that illustrates that sucrose is made of fructose and glucose. Regarding candy, the reading describes how heating a sugar solution produces a supersaturated solution. A discussion about common tec

What's a quick way to unroll a roll of toilet paper? This material is part of a series of hands-on science activities designed to arouse student interest. Here students use Bernoulli's principle and an electric leaf blower to force air over the top of the toilet paper to quickly unroll it. The activity includes a description, a list of science process skills and complex reasoning strategies being used, and a compilation of applicable K-12 national science education standards. Also provided are c

Bat talk
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

Science Sampler : Rockin' around the rock cycle
The following inquiry-based activities were designed as part of a unit intended to aid students in understanding the rock cycle, with the assumption that, after being taught the lessons in the unit, students would have gone beyond a rote memorization of the rock types and rock cycle. The ultimate goal of this hands-on lesson is that students will know and be able to discriminate between them.
