Students explore how different materials (sand, gravel, lava rock) with different water contents on different slopes result in landslides of different severity. They measure the severity by how far the landslide debris extends into model houses placed in the flood plain. This activity is a small-scale model of a debris chute currently being used by engineers and scientists to study landslide characteristics. Much of this activity setup is the same as for the Survive That Tsunami activity in Less
Seismology in the Classroom
Students learn about seismology by using a sample seismograph constructed out of common classroom materials. The seismograph creates a seismogram based on vibrations caused by moving a ruler. The students work in groups to represent an engineering firm that must analyze the seismograph for how it works and how to read the seismogram it creates.
Build it Better!
Students use their knowledge of tornadoes and damage. The students will work in groups to design a structure that will withstand and protect people from tornadoes. Each group will create a poster with the name of their engineering firm and a picture of their structure. Finally, each group will present their posters to the class.
Where Am I: Navigation and Satellites
How do we know where we are? What happens if you are completely lost in the middle of nowhere? Does technology provide tools for people lost in their travels? A person cannot usually determine an accurate position just by looking out a window in the middle of the ocean or vast area of land, particularly if it has not been charted before. In this lesson, students explore the concept of triangulation that is used in navigation satellites and global positioning systems designed by engineers. Also,
Students will design and build a device to protect and accurately deliver a dropped egg. The device and its contents represent a care package that must be safely delivered to people in a disaster area with no road access. In a similar fashion to a team of design engineers, students will design their devices using a number of design constraints including limited supplies. The activity emphasizes the change from potential energy to kinetic energy of the device and its contents and the energy trans
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.
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
