PRAXIS 5005 Science Latest Update Graded A Scientific Method Question Hypothesis (stated as a fact) Prediction ( clarifying the hypotheses) (video example) Test Analysis Name the 3 basic units of measurement and what they measure 1. Meter: length 2. Liter: volume 3. Gram: mass 10 The metric system increases and decreases by units of... Significant numbers are... all non zero numbers, zeros between numbers, and zeros to the right of the number. ex 0.01230 sig numbers are: 1230 ___ variable goes on the x axis ___ variable goes on the y axis independent variable goes on the x axis dependent variable goes on the y axis Independent variable the variable being manipulated by the experiment Dependent variable the variable that may change because of the independent variable Mean average add up all numbers and divide Median the "middle" value in the list of numbers in numerical order Mode Number that appears most often Range Difference between highest and lowest number Igneous Rock formed when hot magma cools beneath the ground or lava cools above the ground forms crystal like/ glassy rocks ex: granite and pumus Sedimentary Rock Changed by pressure does not involve heat Usually near water/ involves water sometimes contain fossils forms from previously weathered and erroted material which may have been igneous, sedimentary, rock metamorphic rock. ex: dolemite, limestone Metamorphic Rock Has been changed by great heat and pressure altered, partially remelted ex: slate, marble Petrology the study of rock Geology the study of earth and it's rocks Plate tectonic theory Lithosphere is made up of major and minor plates Sit on viscous (thick fluid) part and move with it There types of plate boundaires 1. Transform boundaries: they slide past each other causing friction/ earthquakes 2. Divergent boundaries: two plates that pull away from each other/ creates new crust 3. Convergent boundaries: plates push into each other/ one goes under
