  • atom – The basic unit of a chemical element. Atoms are made up of a dense nucleus that contains positively charged protons and uncharged neutrons. The nucleus is orbited by a cloud of negatively charged electrons.
  • cell – The smallest structural and functional unit of an organism. Typically too small to see with the unaided eye, it consists of a watery fluid surrounded by a membrane or wall. Depending on their size, animals are made of anywhere from thousands to trillions of cells. Most organisms, such as yeasts, molds, bacteria and some algae, are composed of only one cell.

Fahrenheit (ºF) * Fahrenheit is a measure of temperature that is abbreviated F. Water freezes at 32°F and boils at 212°F. This scale was developed by Gabriel Daniel Fahrenheit in 1714. The Fahrenheit scale is used in the USA but not in many other countries. The degrees in Fahrenheit are smaller than those in Celsius, making weather-related temperatures more easily written (without having to use a decimal point). enchanted
