Microscopes allow scientists to examine everyday objects in extraordinary ways. They provide high-resolution images that show objects in fine detail. This articles includes details on how microscopes work and how they enhance the scientific process.
This Planet Really Rocks
This ThinkQuest Junior site contains information and activities about rocks and minerals. Included is information about what a rock is, the major characteristics with examples of sedimentary, metamorphic, and igneous rocks, the rock cycle, the differences between rocks and minerals, how to identify minerals (color, luster, streak, cleavager, hardness, and specific gravity), and the Mohs Scale. Facts about common minerals and their properties, how rocks and minerals are important, and their uses
Fractal Musicand Fractal Music Lab
This first website offers a collection of fractal music using images created by G.W.F. Albrecht. The technology and mathematics which this presentation draws on is described on the second website. The second website, developed by David Strohbeen, offers some basic information about fractals and fractal music. He has also posted some samples of his music and invites visitors to download software for creating fractal music and to submit their own compositions.
Water reclamation plant (RealVideo)
In this video clip, students see how wastewater is treated at a water reclamation plant. One of the plant's operators gives Bob the Vid Tec (a children's programming host) a tour of the plant, describing along the way what happens at each step in the water treatment process. For example, the operator explains that microorganisms are used to consume human waste in the biological nutrient removal step. Bob also talks with another plant operator about why kids should learn about wastewater treatmen
The resources found on this web site can be used by individual teachers or teacher groups interested in expanding their use of assessment tools designed to inform teaching practice. Teachers will find the assessments and the supporting materials valuable additions to any professional development focused on assessment.
This brief biography of the originator of the Theory of Continental Drift, Alfred Wegener, covers his background and some of his other work in addition to his 1912 book, The Origin Of Continents And Oceans. In addition, the site explains the evidence that brought Wegener to his conclusion, the early rejections, and his final vindication. It also provides information about some of his personal interaction with others. In addition, there is a link to information about his work in Greenland.
Tech Trek: Time For Class
One of the most abstract concepts that you will teach to your students is the concept of time. Usually introduced at the beginning of the school year, the concept of time is taught along with measurements and scientific units such as length, mass, and volume. However, unlike length, mass, and volume, time can be a very confusing concept to understand. This overview of the concept of time also links to internet resources and includes several classroom extension ideas.
A creative encounter of the numerical kind : A WebQuest for middle grades math students
In this WebQuest, students help an imaginary civilization develop a number system. They work in teams to explore place value, counting, and different number systems. After this preparation, they create and name a set of original number symbols for a base four number system and explain it in a formal presentation.
What is a method of active solar energy production? This article, part of a series about the future of energy, describes the use of large reflector power plants in the Mohave Desert. Students are introduced to the use of large solar reflectors to heat molten salt and produce energy for homes. Students view four photographs of different aspects of the solar complex.

Valley Springs Snow Cream
Middle School, difficulty level 2. Compare the volume of a sphere, cone, and cylinder using ice cream.
This is the introductory page for a set of materials about agronomy as a career. A general description of the work done by agronomists is first provided. In the rest of the resource, students can read narratives about a field sales agronomist and a crop production specialist. Each of these agronomists has provided a challenge activity for students. In one activity, students make brochures and suggest reasons why their sales company is better than a competitor's. Another activity asks students to
This web page focuses on watersheds, the topic of one of the books in the curriculum series that the larger web site accompanies. The page mentions why it can be beneficial for students to investigate local watersheds. The term watershed is defined, and examples of different sizes of watersheds are given. In addition, the page explains why local governments often manage watersheds. Links are provided to water quality experiments, to related online materials on other sites, and to information abo
The future of energy, efficiency
Energy-efficient appliances and vehicles can greatly reduce the amount of energy Americans use. This informational piece, part of a series about the future of energy, introduces students to the consequences of using energy more efficiently. An example about baking a pie provides students with a practical definition of efficiency. A discussion of energy-efficient appliances and processes follows as students read about the Energy Star label. The overall efficiency of a power plant is described, sh
Light and optics
It doesn t take Superman s special strength to take light and bend it, bounce it, or divide it. Teachers and students can read this series of brief articles to learn how the properties of light allow these optical wonders to happen in everyday life. You can navigate through the sections of the module by clicking on objective statements or connect to additional readings or activities through links at the bottom of the pages. Each article has photographs that represent the objective. For example,
Maximize Student Time On Task
Student time on task is the most influential factor in student achievement. To maximize time on task, teachers need to make decisions about the systems they install in their classroom well before any students enter the room. Beginning the school year by explicitly teaching process skills and having classroom operating systems that reinforce process skills are two strategies that lay the foundation for logical thinking throughout the year, which are discussed in this article.
Stats for Schools
Stats4schools, developed by the United Kingdom's Office of National Statistics, is about helping teachers and pupils to get more from statistics. The project has posted here datasets collected by the Office for National Statistics as part of the Omnibus survey and made them available for students to download free of charge. Teachers will also find lesson plans, worksheets and datasets that can be used in their classrooms. The lesson ideas are organized by topics and involve using statistics to a
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
Activity : Fusion Reactions
This activity gives students an opportunity to learn about the elements created in the cores of high-mass stars by fusion reactions. They will discover that all stars start by burning hydrogen and end up creating many heavier elements inside their cores, elements that will be released into space when it dies in a supernova explosion. Students associate a layer with an element that is being produced by the high-mass star. This will illustrate that as the temperature of the star increases with dep
Don't Crack Humpty
Student groups are provided with a generic car base. The groups then design a device/enclosure that will protect an egg on or in the car as it is rolled down a ramp at increasing slopes. Students will be expected to perform basic mathematical calculations using their data.
