Required Vocabulary – IB 12 Higher Level Physics and Physical Measurement 1. Fundamental Units – seven basic units of the SI measurement system: kilogram‚ second‚ mole‚ meter‚ ampere‚ Kelvin‚ candela. 2. Derived Units – units that are combinations of fundamental units. These combinations may or may not have a separate name. (eg. 1 kg m/s2 = 1 N) 3. Accuracy - An indication of how close a measurement is to the accepted value (a measure of correctness). 4. Precision - An indication

choosing the pain of discipline over the ease of distraction. And that’s exactly what delayed gratification is all about” I think that is very true. Delayed gratification is just waiting for something better. If a kid doesn’t pass the marshmallow experiment parents start to wonder what they should do. Mischel states he would remind the parents that there are a large number of cognitive skills that can be used and practiced if kids have a serious self-control problem. At one point Mischel used poker

play and watch soccer games all of the time and yet few people actually realize the physics that are involved in almost everything that they see or do. While there are multiple ways that physics is used in a soccer game‚ this paper explores three parts and the physics that are involved in each one. The three parts that are going to be discussed are passing‚ heading‚ and throw-ins. These three can explain how physics can work from a soccer ball coming or going in each and every direction. Also‚ every

The effect of varying temperature on thee Rennin enzyme Abstract The purpose of this experiment was to see what affect different temperate had on the reaction rate of the enzyme rennin. The experiment was performed by placing test tubes filled with renin and milk into water bath which was heated or cooled to one of the temperatures trialed. The hypothesis justified because it found because it though data that the enzyme reacted faster with the 45° temperate because it was
