Large predators are uncommon in tropical rainforests because large prey species are also rare. The carnivores that do exist have adapted to be able to hunt above ground in the forest canopy as well as on the ground; they have…
There are two conventional ways of writing the equation of a straight line. One type of equation is called point-slope form, and it requires you to know (or find out) the slope of the line and the coordinates of one…
Force, as a physics concept, is described by Newton’s second law, which states that acceleration results when a force acts on a mass. Mathematically, this means: (F=ma) although it is important to note that acceleration and force are vector quantities…
Thermodynamics is the field of physics concerned with temperature, heat and, ultimately, energy transfers. Although the laws of thermodynamics can be a little tricky to follow, the first law of thermodynamics is a simple relationship between the work done, heat…
We may receive a commission on purchases made from links. The largest tropical rainforest on Earth, the Amazon provides one of the richest examples of biodiversity on the planet. Rainforest resources provide numerous benefits that impact the entire planet, from…
Many people know or have encountered — sometimes with painful results — large nests of certain communal wasp species, like the paper wasp, sometimes found in the rafters of old barns or porches. Some types of wasp species take to…
One of the many important observations made by Italian astronomer and physicist Galileo Galilei was that the density of liquid changes — expands and contracts — with temperature variation. This observation led to the creation of the Galileo thermometer, a…
In any scientific experiment, the scientist controls for the variables within the experiment. If more than one variable influences the experiment, the outcome becomes difficult to determine. For example, if one set of plants grows inside and another set of…
Don’t let the name scare you. Swamp grass can compliment a nice perennial garden. The grasses are associated with the Everglades and other swampy marshes, and but can come in many different varieties. Each type is a bit unique and…
The thermometer is humanity’s oldest heat-measuring tool, dating all the way back to the 1600s. Today, different kinds of thermometers can measure everything from outdoor temperature to the temperature of cooked meat. Other tools can measure the heat of entire…
