angle: The space (usually measured in degrees) between two intersecting lines or surfaces at or close to the point where they meet.
application: A particular use or function of something.
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.
balsa: Trees of the Ochroma genus that grow in the tropical Americas. Their wood is extremely lightweight, easy to cut and buoyant. That’s why it’s often used to make rafts, model airplanes and other projects that may require light weight and the ability for someone to sculpt parts easily.
carbon dioxide: (or CO2) A colorless, odorless gas produced by all animals when the oxygen they inhale reacts with the carbon-rich foods that they’ve eaten. Carbon dioxide also is released when organic matter burns (including fossil fuels like oil or gas). Carbon dioxide acts as a greenhouse gas, trapping heat in Earth’s atmosphere. Plants convert carbon dioxide into oxygen during photosynthesis, the process they use to make their own food.
climate: The weather conditions that typically exist in one area, in general, or over a long period.
component: Something that is part of something else (such as pieces that go on an electronic circuit board or ingredients that go into a cookie recipe).
conductive: Able to carry an electric current.
current: (in electricity) The flow of electricity or the amount of charge moving through some material over a particular period of time.
DNA: (short for deoxyribonucleic acid) A long, double-stranded and spiral-shaped molecule inside most living cells that carries genetic instructions. It is built…
