6. anything that has mass and takes up space
9. tiny organisms that are made of a single cell
11. the moment when two objects hit each other
14. absorbing energy
15. to move from one object to another or one place to another
16. an elementary particle that has a negative charge of electricity and travels around the nucleus of an atom
19. a number that summarizes a set of data and that can be computed by adding all the numbers in a list and then dividing by the number of numbers in the list
20. a measure of how hot or cold something is
21. energy the total kinetic energy of all the molecules that make up a sample
23. an uncharged atomic particle that has a mass nearly equal to that of the proton
24. when something stays mostly the same over time
