The missions include interesting clues, fun games, and stimulating quizzes. Users obtain chemical elements as an award for each mission they successfully complete with the ultimate goal of filling the Periodic Table. Through the activities developed by the National Film Board of Canada (NFB), students can learn about lightening, cloud types, elec
Hawaii Coral Reef Assessment and Monitoring Program: Bibliographic Database
This coral reef-related Bibliographic Database was developed by the Hawaii Coral Reef Assessment and Monitoring Program (CRAMP). CRAMP conducts research "designed to identify the controlling factors, both natural and anthropogenic, contributing to the stability, decline, or recovery of Hawaiian reefs. The CRAMP "Bibliographic Database contains listings for published and unpublished documents concerned with the coral reefs and inshore marine resources of Hawaii." More than 2,500 references are cu
Presented by the Museum of Science, Boston, the Ocean's Alive Web site takes a look into the fascinating world of oceans. The Water Planet link has information about the physical features of oceans, how they've been created, the water cycle, and ocean profiles. Other links explain ocean currents, winds and waves, tides, life in the sea, and scientists who study the oceans. The site contains good and easy-to-read descriptions, along with unique and interesting illustrations that make it fun to ex
How high? : geometry (grades 6-8)
With this virtual manipulative, the student investigates conservation of volume with a virtual simulation of pouring a liquid from one container to a container of the same shape, but of a different size. There are four cylinder shapes to choose from: rectangular prism, cylinder, cone, and pyramid. The left container is partially filled with liquid and the base dimensions of the two cylinders are given. The student uses a slider to estimate how high the liquid will rise when poured into the secon
Using technology to support Limited-English-Proficient (LEP) students' learning experiences
This article examines the challenges and rewards related to using technology as a tool to increase learning for limited English-proficient (LEP) students. The article is based on the belief that students' content, linguistic, and technology skills should be developed in tandem. Strategies and standards for technology use are featured along with suggestions for enhancing LEP students comfort level in content classes. Access and equity and the redefinition of teacher roles are also discussed. Impr
An Earth Science Scrapbook Project as an Alternative Assessment Tool
Scrapbooking is a popular hobby and as such, has found its way into educational settings, primarily in middle and elementary school levels. This article describes a scrapbook project that is used both as a means of demonstrating the connections between geology and students daily lives and as an alternative form of assessment. The project was developed for an introductory Earth Science class for middle school and high school pre-service teachers.
Healthy proteins from the evil weed
This article discusses how a genetically modified version of the tobacco plant offers the promise of a new method for manufacturing therapeutic proteins that is both inexpensive and safe.
How to obtain particles to accelerate
Where do the particles come from that are accelerated in a particle accelerator? In this portion of a particle physics tutorial, three sources of particles are described for students. The first source is electrons, which come from heated metals. The second is protons, which are available from ionized hydrogen. Antiparticles are the third source. They are collected by magnetic fields after particles smash targets. Copyright 2005 Eisenhower National Clearinghouse
Whats It Like Where You Live? Desert
This site provides excellent background information on deserts. Large print and superb pictures make this site very appealing to younger students. Topics include: What is a Desert Like?, Types of Deserts, What causes Deserts?, Deserts of the World, Desert Plants, Desert Animals, and links to other desert sites.
This easy to read page includes a biography of Chadwick who discovered the neutron, a photo of Chadwick and links to related people such as Rutherford.
Early algebra, early arithmetic : class materials
This site contains access to over 50 lessons developed as part of a research project that examines how students develop algebraic thinking. The lessons offer teachers in grades 1-6 and parents ideas for situating arithmetic in the context of algebra. The aim of the lessons is to inspire teachers to try new approaches to teaching mathematics. The first lesson is very detailed and provides an introduction to the concepts in later lessons. The use of lessons in sequential order allows students to s
Problems with a Point
A collection of problems designed to help students in grades 6-12 learn new mathematical ideas by building on old ones. Varying in difficulty and approaches, these problems are useful for teachers, students, parents, math clubs, home-schoolers, and others. Problems are classified by topic, time required, suggested technology, required mathematical background, and habits of mind that students develop or use as they work. Synopses of the problems are keyword searchable. Answers and solutions are p
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?
Matching the Motion
Students will learn about slope, determining slope, distance vs. time graphs through a motion filled activity. They will be split into groups with calculators and CBL motion detectors and attempt to match the graphs and equations given to them with the output from the detector that is displayed on their calculators.
Magnetic Fields Matter
This lesson introduces students to the effects of magnetic fields in matter addressing permanent magnets, diamagnetism, paramagnetism, ferromagnetism, and magnetization. First students must compare the magnetic field of a solenoid to the magnetic field of a permanent magnet. Students then learn the response of diamagnetic, paramagnetic, and ferromagnetic material to a magnetic field. Now aware of the mechanism causing a solid to respond to a field, students learn how to measure the response by l
Conduction, Convection, and Radiation
With the help of simple, teacher-led demonstration activities, students learn the basic concepts of heat transfer by means of conduction, convection, and radiation. Students then apply these concepts as they work in teams to solve two problems. One problem requires that they maintain the warm temperature of one soda can filled with water at approximately body temperature, and the other problem is to cause an identical soda can of warm water to cool as much as possible during the same thirty-minu
