bond: (in chemistry) A semi-permanent attachment between atoms — or groups of atoms — in a molecule. It’s formed by an attractive force between the participating atoms. Once bonded, the atoms will work as a unit. To separate the component atoms, energy must be supplied to the molecule as heat or some other type of radiation. computer model: A program that runs on a computer that creates a model, or simulation, of a real-world feature, phenomenon or event. crystal: (adj.

asthma: A disease affecting the body’s airways, which are the tubes through which animals breathe. Asthma obstructs these airways through swelling, the production of too much mucus or a tightening of the tubes. As a result, the body can expand to breathe in air, but loses the ability to exhale appropriately. The most common cause of asthma is an allergy. Asthma is a leading cause of hospitalization and the top chronic disease responsible for kids missing school.

activated charcoal: (also known as activated carbon) A form of carbon that comes as a powder or small granules. It is used to filter out things that may be harmful, smelly or impart a bad taste. The impurities sorb (attach) to the carbon. The small size of the particles increases the carbon’s surface area. So does the particles’ rough surface, which — like a sponge — has lots of pores that offer even more sites at which impurities can attach.
