Description of the principle of operation of a smoke detector/alarm that uses ionising radiation. Diagrams and a simplified circuit are included.
Hurricane Mitch from TRMM: October 27, 1998 with Two Surfaces
A fly-in to Hurricane Mitch on October 27, 1998, showing the three-dimensional structure of the precipitation as measured by the Precipitation Radar instrument on TRMM. In this animation, a surface of constant precipitation colored by the value of the precipitation on the ground under the surface is revealed, then a second surface of higher precipitation is revealed. The global cloud cover data was measured by GOES.

Op het einde van deze les kun je iemand advies geven in verband met het voorkomen en behandelen van hooikoorts.
Students reinforce their knowledge that DNA is the genetic material for all living things by modeling it using toothpicks and gumdrops that represent the four biochemicals (adenine, thiamine, guanine, and cytosine) that pair with each other in a specific pattern, making a double helix. They investigate specific DNA sequences that code for certain physical characteristics such as eye and hair color. Student teams trade DNA "strands" and de-code the genetic sequences to determine the physical char
Strength of Materials
Students learn about the variety of materials used by engineers in the design and construction of modern bridges. They also find out about the material properties important to bridge construction and consider the advantages and disadvantages of steel and concrete as common bridge-building materials to handle compressive and tensile forces.
Mechanical energy is the most easily understood form of energy for students. When there is mechanical energy involved, something moves. Mechanical energy is a very important concept to understand. Engineers need to know what happens when something heavy falls from a long distance changing its potential energy into kinetic energy. Automotive engineers need to know what happens when cars crash into each other, and why they can do so much damage, even at low speeds! Our knowledge of mechanical ener
In this video from Outdoor Nevada, learn about the habitat, diet, and defense mechanisms of horned lizards.
Explain which fish you would want to be in this school and why.
Graduate Skills is one of the series of Futures workbooks, which help students choose and prepare for their careers. Like the other workbooks in the series you can dip in and out doing the exercises which are most relevant to you. You might want to include the exercises or the output in your personal development plan or e-portfolio. The aim of this workbook is to introduce you to the concept of graduate job skills and enterprise, looking at which career path you decides to follow. It’s not j
TRMM Rainmap for September 1998: South and Central America
Monthly average rainfall over South and Central America for September 1998 as measured by TRMM. High rainfall rates are in red.
In this activity, students act as environmental engineers involved with the clean up of a toxic spill. Using bioremediation as the process, students select which bacteria they will use to eat up the pollutant spilled. Students learn how engineers use bioremediation to make organism degrade harmful chemicals. Engineers must make sure bacteria have everything they need to live and degrade contaminants for bioremediation to happen. Students learn about the needs of living things by setting up an ex
Induction of Nitrate Reductase in Plant Shoots
A laboratory exercise that uses colormetric assay and corn seedling shoots to study the induction of enzyme activity by a substrate.
Part 1, "[REDACTED]" Censoring Game Politics
Part 1,""[REDACTED]" Censoring Game Politics! Politics is not a topic normally discussed in relation to game rating systems, but censorship of political content--mostly in the form of political symbols--is quite common. Nazi imagery, for example, has a long history of being censored, both in Germany and elsewhere. Exactly why is such political content censored? Whom is it intended to protect? Who is censoring it? What obligation do commercial game makers have to comply with prevailing polit
