What is the metric system a unit of measurement
what is the scientific method a 6 step, organized way to solve problems
what is an inference a logical explanation for something based on observations
what is a qualitative observation a factual description using the senses
what is a quantitative observation a factual description using measurement and numbers
what is a constant something that stays the same throughout the entire experiment to keep it a fair test
give the unit used in the metric system for measuring mass and give as many examples as possible for equipment used to measure this. unit-grams equipment used- triple beam balance/scale
give the unit used in the metric system for measuring liquid and give as many examples as possible for equipment used to measure this. unit-liters equiptment used- beaker/graduated cylinder
give the unit used in the metric system for measuring length and give as many examples as possible for equipment used to measure this. unit-meters equiptment used- meter stick/metric ruler/metric measuring tape
what is the acronym for remembering the prefixes in the metric system King Henry Died Unusually Drinking Chocolate Milk (kilo) (hecto) (deca) (unit/base) (deci) (centi) (milli)
what is the formula for writing a question Does (IV) affect (DV) ex:Does the size of the koosh ball affect the distance it travels
What is an independent variable(IV) the thing in the experiment you are purposefully changing(size of koosh ball, type of gum)
What is a dependent variable(DV) the outcome in the experiment; thing in the experiment that you are measuring (dependent on the IV...get it?)
what is the formula for writing a hypothesis If (something about IV) then (something about DV) because (reason) ex:If we launch different size koosh balls then the largest one will go farthest because it has more mass and will therefore gain more momentum.
