Unit 1 Review Carousel Station 1 Meter = Kilogram = Second = Kelvin = Kilo- = hecto- = deka- = Deci- = Centi- = Milli- = Mass = SI unit for length SI unit for mass SI unit for time SI unit for temperature SI prefix meaning 1000 SI prefix meaning 100 SI prefix meaning 10 SI prefix meaning 0.1 SI prefix meaning 0.01 SI prefix meaning 0.001 amount of material in an object Station 2 A researcher is studying the effect of sleep on aggression, thinking that less sleep will lead to more aggression. She has some people sleep 6 hours per night, some people sleep 3 hours per night and some people sleep as much as they want. She then monitors aggressive behavior during basketball games among participants. Station 3 Station 4 Dependent variable - the variable that may change due to the independent variable Independent variable - the variable that you change in the experiment Control Group - A group that is not changed in an experiment Constant - A factor that does not change when other variables change Observation – Process of gathering information through the senses Station 5 2000 mg = 5L= 16 cm = 104 km = 198 g = 2500 m = 480 cm = 75 mL = 65 g = 5.6 kg = _2.0__ g _5000_ mL _160_ mm _104,000_ m _.198__ kg _2.5__ km _4.8_ m _0.075_ L _65,000__ mg _5,600__ g Station 6 A researcher is curious to find out what effect classical music has on people’s level of relaxation (as measured by heart rate). He suspects that listening to classical music will make people feel more calm and relaxed. He lets one group listen to classical music for one hour. He lets another group sit in a quiet room for one hour (i.e they hear no music). After one hour, he monitors the heart rate of each participant to measure their level of relaxation.
