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

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. |
