Science final
Unit 2
-
-
gas laws
Charles' law, Boyle's law, Daltons law, Avogadro's law
-
-
-
-
-
pressure, volume, temp
the kinetic theory of matter helps us understand pressure, temp, and volume

in unit two it talks about elements and atoms broadly, in unit 3 in goes into detail about elements and
unit 1
six parts of the scientific method:
state the problem/ ask a question
-gather information
-test hypothesis
-analyze data
-draw conclusions
-
-
-
-
control variables: are kept the same throughout the experiment, not being tested, used for comparison
-
-
control group: consists of control variables, remains the same
-
-
-
-
converting in the metric system: if you are going from bigger to smaller go to the right if you are going from smaller to bigger, go to the left, bigger= less #'s, Smaller=more #'s
-
Pie chart: type of chart, good for comparing percentages
-
-
Metric system: kilo, hecto, deka, basic unit, deci, centi, mili King Henry Died By Drinking Chocolate Milk
-
line graph: type of graph, good for comparing things over time
-
-
-
bar graph: type of graph, best used to compare multiple things
-
unit one talks about experiments and in unit two it talks about all of the things involved in experiments like changes, states of matter, and etc.

unit one is about the scientific method and experiments, while unit 3 is about atoms and elements. In experiments it there is a chemical change then the atom changes, you need to understand about the atom for experiments in science
