Across

1. - to speed up
5. - a wire coil around a metal core (usually iron) that acts like a magnet when an electric current flows through it
7. - a piece of iron or other material that attracts other pieces of iron or steel
8. - the science of very low temperatures, far below the freezing point of water
10. - a place equipped for scientific research, experiments or testing
12. - a state of matter with definite volume but no definite shape, like water
14. - former name of Jefferson Lab; stands for Continuous Electron Beam Accelerator Facility
17. - a substance composed of two or more elements, such as water (H2O), carbon dioxide (CO2), or table sugar (C12H22O11)
18. Lab - a nuclear physics research facility built to explore quarks in the nucleus of the atom, located in Newport News, Virginia
23. - a material through which electricity or heat does not flow easily (like many plastics, glasses and ceramics)
24. - particles that hold quarks together
26. - a temperature scale that begins at absolute zero, where there is no molecular movement (Water freezes at 273 K and boils at 373 K.)
27. - a closed path through which an electric current flows
28. - an abbreviation for Linear Accelerator
30. Change - a change in the chemical composition of a substance to produce a new material with new properties (An example of a chemical change is wood turning to ash and smoke when it burns.)
32. - stands for Free Electron Laser; a tunable laser made by wiggling a beam of electrons (Jefferson Lab's FEL is the most powerful in the world.)
33. - a worldwide network of computers linked together for the purpose of exchanging information (also sometimes called the Information Superhighway or Cyberspace)
35. Current - movement of electricity, measured in charges per second (just as river current is measured in liters per second)
36. - information represented in the form of a picture, diagram or drawing
38. - a ray of light; a group of particles traveling together along a well-defined path
40. - any substance that cannot be broken up into simpler substances by chemical means (Currently 115 elements have been observed and are displayed on the Periodic Table of Elements. Gold, silver, iodine, oxygen and nickel are examples of elements.)
41. - a series of actions carried out to test a theory, demonstrate a fact or find out what happens
43. Reaction - a chemical change in which one or more substances are changed into one or more new substances
44. - the first section of an accelerator, where electrons are torn away from atoms and accelerated to an energy sufficient for them to be injected into the cavities of the accelerator
45. - a programmable machine that inputs, processes and outputs data
46. - an acronym for HyperText Markup Language; the programming language or code used for the creation of internet web pages
48. - the capacity to do work
49. - a temperature scale at which water freezes at 32° and boils at 212°
53. Variable - the responding variable; the variable that may change as a result of a change in the independent variable
54. - the transportation of heat or electricity from one place to another directly through an object (A frying pan is warmed by a hot stove due to conduction.)
55. - a temperature scale on which water freezes at 0° and boils at 100°
56. - a pattern of horizontal and vertical lines forming squares of uniform size on a map or chart

Down

2. Properties - characteristics of a substance that determine how it will react with other substances
3. - the acronym for Becoming Enthusiastic About Math and Science
4. Variable - the manipulated variable; the variable that is changed on purpose in an experiment
6. - a group of measurements, facts or statistics
9. - a material (like a metal) through which electricity and heat flow easily
11. - the measure of the amount of matter an object has in it; measured in grams or kilograms
13. - one of the two basic building blocks of matter (An electron is a lepton.)
15. - act with each other
16. - the process of making something look bigger
19. - a person who uses science and math to design, build or operate equipment, structures and systems (A person who receives a college degree in engineering might be an electrical, mechanical, industrial, chemical, environmental, biochemical or aeronautical engineer.)
20. Suspension - a material that has properties of more than one state of matter, such as Jell-o
21. - a set of numbers that determines the location of a point in space
22. - the transportation of heat from one place to another by the movement of a liquid or gas (A classroom is warmed by a hot air blower due to convection.)
25. Accelerator - a machine used in physics experiments that makes particles go faster in a straight line
27. - the amount of electricity carried by a body (A charge can be negative, like an electron, or positive, like a proton. Objects with opposite charges attract one another, while objects with like charges repel one another.)
29. - matter that is exactly the opposite in every way from its matter counterpart: antiquark/quark; positron/electron
31. - something that has mass which can exist in the form of a solid, liquid, gas or plasma
34. - steady; uninterrupted
36. - a state of matter with no definite shape or volume, like air
37. - a machine which accelerates charged particles to high energies
39. - a colorless, odorless, tasteless gas (Helium becomes a liquid near absolute zero. Liquid helium is used to cool Jefferson Lab's accelerator components.)
42. - a tiny particle with a negative charge which orbits an atom's nucleus
47. - a push or pull (There are four basic forces: gravitational, electromagnetic, strong nuclear and weak nuclear.)
50. - an educated guess that can be tested or investigated
51. - an atom or molecule that has an electric charge because it has either gained or lost electrons
52. - the smallest unit of a chemical element, made up of a nucleus surrounded by electrons
