Saltwater, which is found in earth’s oceans and seas, is quite different from the freshwater contained within lakes, rivers and streams across the globe. Plant and animal species are adapted to live in one type of water or the other,…
Calculating the ionization energy of an atom constitutes a part of modern physics that underlies many modern technologies. An atom consists of a central nucleus that contains positively charged protons and a number of neutrons specific to the given atom.…
Metals of all types are important and valuable resources. Although their natural supply or the supplies of elements that go into producing various alloys are fixed, metals are highly recyclable and reusable. Precious metals, such as gold and silver, are…
Whether viewed in movies or experienced in real life, tornadoes are scary! Understanding how tornadoes form is an important aspect of weather science. Plus, demystifying these intense storms can help put them in perspective. TL;DR (Too Long; Didn’t Read) During…
The animal kingdom is full of fascinating examples of predator and prey animal combinations. To make this concept come alive for your youngsters, play predator vs. prey games, focusing on scenarios such as food webs and animal classifications. Some games…
CCF and MCF are standardized units of measurement of natural gas. The initial C in the term “CCF” is the Roman numeral for 100; “CCF” means 100 cubic feet. The initial M in the term “MCF” is the Roman numeral…
The thermal conductivity of a material determines how good an insulator it is. The official definition of thermal conductivity is the quantity of heat transmitted through a unit thickness in a direction normal to a surface of unit area, due…
Meters squared and meters cubed refer to different methods of measuring space. One describes the area of a flat plane, while the other describes the area of a three-dimensional area. However, it is sometimes necessary to convert between one and…
You’ve conquered the naming of compounds and now you’re ready to move onto balancing chemical equations. But the process involves more numbers, and already coefficients seem harder than subscripts. Subscripts in a chemical formula are constant for each compound. Sodium…
Pour an ice-cold drink into a glass on a hot summer day and soon, water droplets will form on the outside of the glass. How does this condensation on glass happen and where does the water come from? An understanding…
