Finding the reference number in your calculus equation can make the difference between passing your introductory calculus test and class, and having to retake the course. The reference number is identified as the shortest distance along the unit 360 degrees…

Plastics remain a valuable material for many products used in everyday life and in more specialized settings. They include durable and non-durable goods, bags, packaging and containers, beverage and food containers. They make up cars, boats and the siding of…

Despite their fearsome reputation, wasps aren’t all bad. Many wasps help control pests in gardens and orchards, and many also serve, whether purposely or by accident, as pollinators. Some of the more beneficial wasps, like the mason wasp, look similar…

Peacocks are opportunistic eaters and the peacock diet is varied. They are not very picky and will make a meal out of many types of food. They are omnivores, meaning peacock food consists of both plants and meat. Peacocks forage…

Along with arachnids, crustaceans and insects belong to the same group—arthropods. Sharing distinctive physical characteristics, such as absence of backbone, hard exoskeletons, jointed legs and segmented bodies, arthropods are easily distinguished from other animal groups. Although the arachnids are easily…

You probably learned early on in science classes that density is mass divided by volume, or the “amount” of a substance in a certain space. For solids, this is a pretty straightforward measure. If you fill a jar full of…

Density, the weight of an object divided by its volume, is a property of all matter, including solids, liquids and gases. The value of an object’s density depends on what it’s made of as well as its temperature; for example,…

A parabola can be thought of as a one-sided ellipse. Where a typical ellipse is closed and has two points within the shape called foci, a parabola is elliptical in shape but one focus is in infinity. An important feature…

The pH scale is used to measure the alkalinity or acidity of a substance like water. The scale goes from 0 to 14. A pH under 7 indicates that what you’re measuring is acidic, and anything over 7 is alkaline.…

Angles are an integral part of geometry, a subject that envelopes the material world around people. Learning about angles gives better insights as to how ordinary objects work. In architecture, for example, an understanding of angles allows a builder to…
