Word problems with multiples and fractions
This lesson asks students to work with word problems involving multiples and fractions of a variable. Beginning with a discussion of what is meant by one-half as much and twice as much, the five-part lesson asks students to represent the problems using algebraic notation, tables, and pictures. The problems involve money, weight, and candy. Questions to facilitate class discussions and guide student work are provided. Reproducible overheads and student handouts are also included.

Why Teach Bioethics?
Adolescents are passionately interested in ethical questions suggesting adolescence may be a critical period for including bioethics in science education. Knowledge arises when the mind interacts with content; an understanding of ethical issues develops as an evolving process around real-life situations. The question is what role should teachers play in the acquisition of this knowledge?

Means, standard deviation, and deciding if two results are different at some level of statistical significance is the basis for analytical decision making. This module teaches students how to use t-tests, Q-tests, and to tell when differences are statistically real.
Animation of single wavelength UV-vis detection for HPLC
This site deals specifically with single wavelength UV-vis detection for liquid chromatography. The animations are short (one to two minutes) and can easily be shown in class as part of a lecture. They are extremely helpful in illustrating key components and concepts of chromatographic systems. Users are encouraged to explore the site and the other brief animations as well. Separate links to other simulations by the same company (TRSL) are also listed on ASDL.
HPLC Tutorial 2,0 Video
This high quality video resource focuses on partition chromatography. The video presents an overview of basic separation theory and discusses instrumentation and data analysis. The size of the video (62.6 MB) almost requires a high speed internet connection. The resource can be downloaded to the user\'s computer, which is recommended for those with slower connections.
"It Was a Wildly Exciting Time": Milton Meltzer Remembers the New Deal's Federal Theatre Project
Part of the New Deal's Works Progress Administration (WPA), the Federal Theatre Project (FTP) was one indication of the breadth of that program. Governments, including that of the United States, had long been important patrons of the arts, but New Deal support for art was unprecedented in American political life. Like the other New Deal arts projects, the FTP treated creative endeavors as work; it used government funds to hire unemployed actors, stage hands, and playwrights Perhaps best known fo
2.10 The complex exponential function
Number systems and the rules for combining numbers can be daunting. This unit will help you to understand the detail of rational and real numbers, complex numbers and integers. You will also be introduced to modular arithmetic and the concept of a relation between elements of a set.
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.
Honeybee Venom Detected by Enzyme Immunoassay
The venom of the honeybee, Apis mellifera, contains numerous enzymes, volatiles, and other components. Allergic individuals develop anti-venom antibodies which may cause hives, anaphylactic shock, and death. In this exercise students detect concentrations of bee venom on nitrocellulose membranes following incubation of membranes with anti-venom antibodies, enzyme-conjugated secondary antibodies, and a colorimetric substrate. The intensity of the colored substrate deposited on the membrane is pro

Roheline Raamat - kuidas saada rikkaks?
Liikumise pakenditöörühma eestvedaja Juhan Ruudu kirjutisest (1997) leiate seisukohti ja näiteid, kuidas igaüks meist, olgu siis üksikisikuna, pereliikmena või ettevõtjana oma elukorraldust ja tarbimisharjumusi analüüsides ning neid pisut muutes tooks kasu keskkonnale. Samas kajastub see muutus tingimata ka inimese nn eelarves märkimisväärse kulutuste vähenemise näol. Rikkamaks peaks lugeja käesolevat elektroonset raamatut lugedes saama igal juhul - kasvõi teadmiste ja ilmaasjad
