Soda is a popular concoction for use in 7th-grade science projects. Soda can be used in experiments on chemical reactions, dental hygiene and carbonation. Soda is also a safe substance to manipulate, making it a perfect experimental material for middle-school…
Insulators are materials that inhibit the flow of electrical current. The opposite of conductors, which allow electric particles to flow freely, insulators are implemented in household items and electrical circuits as protection. Thermal insulation is similar, but it constricts the…
A centimeter is a unit used to measure the length of an object. For example, a pencil is about 15 centimeters long. The abbreviation for centimeter is “cm.” A square centimeter is a unit used to measure the area of…

Whenever electrons move, current is created. In fact, current measures that movement; specifically, it is the charge that moves divided by the time it takes to move (or, if you’ve taken calculus, it’s the derivative of charge with respect to…
