battery: A device that can convert chemical energy into electrical energy.
ChemicalsA substance consisting of two or more atoms united (bond) in a fixed ratio and composition. For example, water is a chemical produced when two hydrogen atoms bond to one oxygen atom. Its chemical formula is H2O. Chemical can also be an adjective to describe the properties of substances resulting from different 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.
chemistryThe field of science that deals with the composition of materials, their structure, their properties, and how they interact. Scientists use this knowledge to study unfamiliar materials, to produce large quantities of useful materials, or to design and create new and useful materials. (in relation to compounds) Chemistry is also used as a term to refer to the recipe of a compound, its method of production, or some of its properties. People who work in this field are known as chemists.
Present: (in electricity) the flow of electricity or the amount of charge that moves through a substance during a certain period of time.
electric current: The flow of electrical charge – electricity – usually from the movement of negatively charged particles called electrons.
electricity: The flow of charge, usually from the movement of negatively charged particles called electrons.
pole: A device that conducts electricity and is used to contact the non-metallic part of the electrical circuit, or touches something through which the electrical signal is transmitted. (in electronics) A portion of a semiconductor device (such as a transistor) that either releases or collects electrons (negative charges) or holes (positive charges)—or can control their movement.
Engineer: A person who uses science and mathematics to solve problems. As a verb, the word “engineering” means to design a device, material, or process that will solve some problem or unmet need.
equationIn mathematics, it is said that two quantities are equal. In geometry, equations are often used to determine the shape of a curve or surface.
fruit: A reproductive organ that contains seeds in a plant.
jelly: A viscous or viscous substance that flows like a thick liquid.
Graphite: Like diamond, graphite (the material found in a pencil) 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: Designated for grades nine through twelfth in the American compulsory public education system. High school graduates can apply to colleges for more advanced education.
planting: A device manufactured to replace a lost biological structure, to support a damaged biological structure, or to enhance an existing biological structure. Examples include hips, knees, and artificial teeth; Pacemaker devices. Insulin pumps are used to treat diabetes. Or some devices are surgically installed in the animal’s body to collect information about the individual (such as its temperature, blood pressure, or activity cycle).
Mechanical Engineer: A person trained in a research field who uses physics to study motion and properties of materials to design, build, and/or test devices.
Metal: Something that conducts electricity well and tends to be shiny (reflective) and flexible (meaning it can be reshaped with heat and not a lot of force or pressure).
middle School: A designation for grades six to eight in the American educational system. It comes right before high school. Some school systems divide their age groups slightly differently, including sixth grade as part of elementary school and then referring to seventh and eighth grades as “junior” high school.
radioReferring to radio waves, or the device that receives these transmissions. Radio waves are part of the electromagnetic spectrum that people often use for long-range communications. Radio waves, longer than visible light waves, are used to transmit radio and television signals. It is also used in radar. Many astronomical objects also radiate some of their energy in the form of radio waves.
Robot: A machine that can sense its environment, process information, and respond with specific actions. Some robots can act without any human intervention, while others are directed by a human.
solid: firm and stable in form; It is neither liquid nor gaseous.
stitch: The length of the thread that connects two or more pieces of fabric.
napkin: Made of cells, which are any of the distinct types of materials that make up animals, plants, or fungi. Cells within tissues work as a single unit to perform a specific function in living organisms. For example, different organs of the human body are often composed of different types of tissue.
