  2. 8. involves separating liquids by boiling them. The liquid with the lower boiling point vaporizing first, leaving the other liquid behind
  3. 9. the measurement of how much mass of a substance is contained in a given volume
  4. 10. has definite shape and volume
  5. 16. system of units used by scientist to measure mass
  6. 18. variable changes or manipulations by scientist (does not depend on other variable - the "cause" of the hypothesis)
  7. 20. a measure of the force of gravity acting on an object
  8. 21. anything that has mass
  9. 23. a neutral group of two or more atoms held together by covalent bonds
  10. 24. can be measured numerically (height, length, or weight)
  11. 25. a factor in an experiment or investigation that changes
  12. 28. variable changes as a result of other variables (depends on other variable - the "effect"
  13. 29. a measure of how much matter is in an object
Down
  1. 1. variable a factor or condition in scientific experiments that intentionally kept constant and unchanged to ensure it does not influence the outcome of the experiment
  2. 2. a substance made of two or more elements chemically combined in a specific ratio or proportion
  3. 3. change a change that alters the form or appearance of a material but does not make the material into another substance
  4. 4. a single kind of matter that is pure and has a specific set of properties
  5. 5. solids quartz with repeating patterns
  6. 6. observed and generally cannot be measured with a numerical result
  7. 7. fluid without a definite shape or volume
  8. 11. property a change that alters the form or appearance of a material but does not make the material into another substance
  9. 12. to change (something) into a different form or property
  10. 13. two or more substances that are together in the same place - but their atoms are not chemically bonded
  11. 14. property a characteristic of a substance that describes its ability to change into different substances
  12. 15. a pure substance that cannot be broken down into other substances by chemical or physical means
  13. 17. the basic particle from which all elements are made - the smallest particle of an element that has the properties of that element
  14. 19. solid not arranged in a regular pattern
  15. 22. the explanation of scientists based on their current understanding and research
  16. 26. the amount of space that matter occupies
