battery: A device that can convert chemical energy into electrical energy.
chemicals: A substance formed when two or more atoms combine (bond) together in a certain ratio and structure. For example, water is a chemical formed when two hydrogen atoms combine with one oxygen atom. Its chemical formula is H2O. Chemical can also be used as an adjective to describe the properties of materials that result from various reactions between different compounds.
chemical engineer: A researcher who uses chemistry to solve problems related to the production of food, fuel, medicines, and many other products.
chemistry: The field of science that deals with the composition, structure, and properties of matter and how they interact. Scientists use this knowledge to study unknown materials, reproduce useful materials in large quantities, and design and create new and useful materials. (of compounds) Chemistry is also used as a term to refer to a recipe for a compound, a method for making it, or some of its properties. People who work in this field are known as chemists.
the current: (in electricity) the flow of electricity or amount of charge that moves through some substance over a specified period of time.
currentFlow of charge (electricity). It is usually caused by the movement of negatively charged particles called electrons.
electricity: Flow of charge. It is usually caused by the movement of negatively charged particles called electrons.
electrode: A device used to conduct electricity and make contact with a nonmetallic part of an electrical circuit, or with something through which an electrical signal passes. (In electronics) Part of a semiconductor device (such as a transistor) that can emit or collect electrons (negative charge) or holes (positive charge), or whose movement can be controlled.
engineer: A person who uses science and mathematics to solve problems. As a verb, “engineering” means to design a device, material, or process that solves some problem or unmet need.
equation: In mathematics, a statement that two quantities are equal. In geometry, equations are often used to determine the shape of curves and surfaces.
fruits: The reproductive organs of a plant that contain the seeds.
gel: A sticky, viscous substance that flows like a thick liquid.
graphite: Like diamond, graphite (the substance found in pencil lead) is a form of pure carbon. Unlike diamond, graphite is very soft. The main difference between these two forms of carbon is the number and type of chemical bonds between the carbon atoms in each substance.
high school: Designation of grades 9 through 12 in the U.S. compulsory public education system. High school graduates can apply to university for further advanced education.
implant: Devices manufactured to replace lost biological structures, support damaged biological structures, or strengthen existing biological structures. Examples include artificial hips, knees, and teeth. pacemakers; and insulin pumps used to treat diabetes. or any device that is surgically placed inside an animal to collect information about the individual (temperature, blood pressure, activity cycles, etc.).
Bachelor of Mechanical Engineering: A person trained in a field of research that uses physics to study motion and the properties of materials to design, build, and test devices.
metal: Something that conducts electricity well, is shiny (reflective), and malleable (that is, it can change shape with heat and is not subjected to much force or pressure).
junior high school: The designation for grades 6 through 8 in the U.S. education system. It is located just before high school. Some school systems have slightly different age classifications, with 6th grade being part of the elementary school, and 7th grade and her 8th grade being referred to as “middle school” and high school.
wireless: Refers to radio waves or the device that receives these transmissions. Radio waves are a part of the electromagnetic spectrum that people often use for long-distance communication. Radio waves, which are longer than visible light waves, are used to transmit radio and television signals. It is also used in radar. Many celestial bodies also radiate some of their energy as radio waves.
robot: A machine that can sense its surrounding environment, process information, and respond with specific actions. Some robots can operate without human input, while others follow human instructions.
solid: The shape is solid and stable. It's neither a liquid nor a gas.
stitch: A length of thread that joins two or more pieces of fabric.
organization: Made of cells, the various types of substances that make up animals, plants, and fungi. Cells within tissues function as units to perform specific functions in living organisms. For example, different organs in the human body are often made from many different types of tissue.
