Being able to quickly and accurately convert watts into volts is essential for a range of engineering disciplines. Amps, volts, and watts are part of a triad where when two quantities are known the third can be calculated, using the…
Often brightly colored with large, fan-like tails that can span 60 inches, peacocks are the male members of a species of bird know as peafowl, which are in the same family as the pheasants native to North America. Peacocks are…
Delta landforms occur where rivers dump loads of sediment – silt, sand and small rocks – at their mouths in oceans or large lakes. The Nile delta in the Mediterranean Sea, the Mississippi delta in the Gulf of Mexico, the…
Plants and algae act as the food bank of the world thanks to their amazing photosynthetic powers. In the process of photosynthesis, sunlight is collected by living organisms and used to produce glucose and other energy-rich, carbon-based compounds. Scientists find…
A cat by any other name would still be feline, but taxonomists — scientists who classify living things — would not be able to communicate nearly as much information as they can through the scientific name Felis catus. The seven…
Potato experiments help younger scientists to explore water solubility, natural reactions and electromagnets. Some experiments use water, while others need the help of aluminum foil. With some household items, fun science experiments with potatoes increase a child’s understanding of how…
Circles have properties that are common to all of them. One such property is the relationship between a circle’s diameter and its radius. You can use this property, when it’s expressed as an equation, to solve for the radius of…
You may have seen the abbreviation kPa, for kilopascals, printed on the pressure gauge you use for the tires of your car. One kilopascal equals approximately 0.145 pounds per square inch (psi). Because the kilopascal is a unit of pressure,…
Growing plants as part of a science fair project is a popular experiment as it allows for great variation in methodology. There are a number of variables that can be used to monitor growth including sunlight, soil conditions and temperature.…
At the time of European settlement, the New England state of Massachusetts harbored three types of wild cats: the **puma (also known as the cougar, mountain lion, catamount or panther), the Canada lynx and the bobcat**. Of these, only the…
