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
Lost in the Amazon
The Lost in the Amazon curricular unit is a series of minds-on and hands-on engineering activities based in the Amazon rainforest in Brazil. Motivated by an adventurous theme, students discover, learn and apply the following: 1) Classification of Plants and Insects; 2) General Categorizing Skills; 3) Process Skills: Problem Solving and Critical Thinking; 4) Scientific Testing and Experimentation; 5) Properties of Materials The investigative, exploratory and problem solving nature of Lost in the
Rocks, Rocks, Rocks
Student teams will test rocks to identify and record rock properties such as luster, hardness, color, etc., and classify rocks as igneous, metamorphic and sedimentary. They will complete a worksheet table with all of their rock properties, and then answer some worksheet questions to deepen their understanding of rock properties and relate them to the cavern design problem.
Protests erupt across Syria
Protesters took to the streets in several Syrian cities on Friday - in a direct challenge to the rule of President Bashar al-Assad. Jon Decker reports.
Travel With Care Safety Tip 1
The City of Auburn and Auburn University have partnered to bring Travel With Care Auburn, a public safety campaign aimed at audiences using all forms of transportation: motorists, pedestrians, cyclists, and transit riders. Throughout the week of April 4-8, members of the Auburn Public Safety - Police Division will be patrolling city streets and the Auburn University campus to bring awareness to traffic issues, while student volunteers will pass out informational brochures.
A Walk along the Kennet
Description not set
Students learn about the physical force of linear momentum movement in a straight line by investigating collisions. They learn an equation that engineers use to describe momentum. Students also investigate the psychological phenomenon of momentum; they see how the "big mo" of the bandwagon effect contributes to the development of fads and manias, and how modern technology and mass media accelerate and intensify the effect.
6.4 Technology and environment
Global warming: are we responsible? Is our environmental impact damaging the planet? This unit examines the use of ozone depleting technology, the impact of fossil fuel use and explores how the development of technology can influence the direction of a society. From the Industrial Revolution to the present day find out how we have changed the planet.
More Is More
The goal of our project is to promote awareness of the dangers of misusing combination products and to emphasize the importance of checking drug fact labels for the active ingredients in over the counter medications. Our target audience is consumers.
Are you about to undertake a PhD in science, technology or mathematics? If so, this unit will help you to examine your work processes. You will consider and develop the nature of postgraduate work and look at the planning of work needed at doctoral level.
