Students will learn about the importance of water and the role it plays in our lives. Students will be exposed to what must occur each day so that they can have clean water.
The Boxes Go Mobile
To display the results from the previous activity, each student designs and constructs a mobile that contains a duplicate of his or her original box, the new cube-shaped box of the same volume, the scraps that are left over from the original box, and pertinent calculations of the volumes and surface areas involved.
Heredity Mix ’n Match
Students randomly select jelly beans (or other candy) that represent genes for several human traits such as tongue-rolling ability and eye color. Then, working in pairs (preferably of mixed gender), students randomly choose new pairs of jelly beans from those corresponding to their own genotypes. The new pairs are placed on toothpicks to represent the chromosomes of the couple’s offspring. Finally, students compare genotypes and phenotypes of parents and offspring for all the “couples” in
The Evening News
In this lesson, the students will summarize their experiences in the Amazon rainforest by developing and presenting a briefing for a T.V. evening news program.
18.712 Introduction to Representation Theory (MIT)
The goal of this course is to give an undergraduate-level introduction to representation theory (of groups, Lie algebras, and associative algebras). Representation theory is an area of mathematics which, roughly speaking, studies symmetry in linear spaces.
How it's Made - Lithium Ion Batteries
Batteries are examples of stored energy, chemical potential energy to be exact. But how are batteries made and what is inside? This is a segment from the Discovery Channel series "How it's Made" on lithium ion batteries.(05:36)
Six Science bloggers talk about why they blog, the role of blogging in science, feedback they've received, and the greatest microbiological discovery in the past decade.
LC Calc (TM) Online. A handy calculator for HPLC computations.
This site contains several on-line calculators for use in liquid chromatography. These include pressure unit conversion, buffer pH, and scale-up factors. Some links may be broken.
Changing the World: Jeff Freeman
Oregon State University alum Jeff Freeman is making the world a better place. He is currently the Knife Innovation Manager at Gerber Legendary Blades.
Animation of Single Head Check Valve HPLC Pump
This animation site is specifically about reciprocating pumps 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.
GC coating animation
This site is one in a series of sites with very good animations related to separations. This animation deals specifically with solute retention in GC. 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 a
Electronics - Tutorial
An encyclopedic collection of descriptions of electronics circuitry and principles to introduce or reacquaint readers with a wide variety of concepts. The site is very well organized to access the information needed. In addition to passive and active components, electricity and magnetism are also described.
Population Genetics and Statistics
This website is part of the President\'s DNA Initiative and is devoted to past and current methods of macromolecules such as DNA. This website introduces the student to the subject of population genetics and stresses factors that can alter allele frequencies in a population and calculations associated with the Hardy-Weinberg principle. The student will learn to use acceptable statistical approaches to evaluating DNA data and how DNA databases are constructed and applied. This site is designed as
DNA Amplification for Forensic Analysts
This web site describes the ampification polymerase chain reaction (PCR)process typically employed for the forensic analysis of DNA. Emphasis is placed on the selection of core short tandem repeat(STR)and Y-STR loci for conducting PCR. The concept of multiplexing is reviewed.The site is designed as an on-line short course with excellent graphic support. The user must register and secure a readily obtainable password prior to entering the site
Kids in the Hall of Planet Earth
This geology Web site for kids, part of the museum's Kids in Our Halls program, was created by high school interns at the Museum. It includes: Kids Interview Kids, in which kids visiting the Hall of Planet Earth are asked geology questions and scientists' answers are given alongside the kids' article that recounts how Dr. Richard Ash survived snake encounters during an expedition to collect meteorites an online challenge in which kids see which standard kitchen items contain rocks and minerals,
Phylogeny determined by protein domain content
A simple classification scheme that uses only the presence or absence of a protein domain architecture has been used to determine the phylogeny of 174 complete genomes. The method correctly divides the 174 taxa into Archaea, Bacteria, and Eukarya and satisfactorily sorts most of the major groups within these superkingdoms. The most challenging problem involved 119 Bacteria, many of which have reduced genomes. When a weighting factor was used that takes account of difference in genome size (numbe
Car Safety Tips in Children
This three minute video shows the importance of using baby seats in cars. It does not tell you how to identify a good one and is weak on showing how they should be belted at different ages. At best, this is a warning video for parents.
3.8 Evaluating strategy and presenting outcomes By now you will have found out about and sampled different resources for learning and used different ways to learn. But the structured approach used in this section is one of the main resources for developing and improving your other key skills. So how do you know if you have learned? How do you know if you have improved? How do you know if you are meeting the standard for improving your own learning and performance expected of someone doing a course in higher education or using higher
