 Mass a measure of how much matter is in an object constant Weight The measure of the force of gravity on an object 6 times less on the moon Density A measurement of how much mass of a substance is conatained in a given volume Think Mass/Volume Inference A logical interpretation based on observations and prior knowledge Think I-I Hypothesis A possible explanation for a set of observations or an answer to a scientific question: MUST BE TESTABLE Nope... Manipulated Variable the one factor a scientist changes in an experiment Independent variable Responding Variable the factor that changes as a result of the manipulated variable in an experiment Dependent variable Controlled experiment an experiment in which all variables except one are kept constant Control!!!!!!!!! Science a way of learning about the natural world through observations and logical reasoning leading to a body of knowledge duh........ Scientific theory a well tested idea that expplains and connects a wide range of observations ......nope scientific law a statement that describes what scientists expect to happen every time under a particular set of conditions LAW not theory volume a measure of how much space matter occupies(lxwxh) not constant centimeters cubed (cm3) the unit for measuring volumes of solids (mL=cm3=cc) nopers grams per centimeter cubed (g/cm3) unit used to measure density of a solid blah density formula mass diveded by volume (mass/volume) milli .001 = one thousandTH of a meter/gram/liter K-H-D-M-D-C-M centi .01 = one hundredTH of a meter/gram/liter K-H-D-M-D-C-M deci .1 = one tenTH of a meter/gram/liter K-H-D-M-D-C-M deka x10 = 10 meters/grams/liters K-H-D-M-D-C-M hecto x100 = 100 meter/grams/liters K-H-D-M-D-C-M kilo x1000 = 1000 meters/grams/liters K-H-D-M-D-C-M meter in 1875 scientists calculated 1/10000000 of the distance from the equator to the north pole K-H-D-M-D-C-M meniscus the bottom of the curved surface(line) that determines the measurement(for volume) of a liquid(or irregular shaped object) in a graduated cylindar Think Krawczuk... Celcius the temperature scale on which 0 and 100 are the temps. at which water freezes and boils not Farenheit Gram In 1875 scientists decided to use water measured at sea level at 23 degrees C 1 gram = 1 mL of WATER K-H-D-G-D-C-M Liter the standard unit of volume of metrics 1 liter = 1000 cm3 K-H-D-M-D-C-M
