Describing matter
What is mass, how do you measure it, and what units do you use to measure it.
describes the amount of matter in an object, triple beam balance, g and kg
what do you do if there is a fire?
cover if in a container, fire extinguisher, smother with blankets if on person
what do you wear that you get from the classroom
what makes up a good scientific question?
not too broad, cna be answered by investigation/experiment, has a falsifiable hypothesis, concerns changes that can be observed
what is matter?
anything that has mass and takes up space
What is volume, what do you measure it with, and what units do you use.
the amount of space that an object takes up/occupies, H20 displacement + formulas (l x w x h), mL, cm3, meters, millimeters
what do you do if there is broken glass?
notify teacher, sweep with dustpan and broom if needed
what should you wear
no baggy clothes, close-toed shoes
based on a person's observations and previous knowledge, testable, descriptive and specific, written as an if. . . then statement
what is chemistry
the science that deals with substances and various forms of matter
what is density, how do you measure it, what units do you use
the amount of matter in a given volume, density triangle + formulas(M=DxV), g/mL + g/cm3
chemicals
dispose of in special disposal tub, don't put in trash or down sink, if on you go to the hose.
what else should you do?
hair tied back, no jewelry
experimental design - constants/controlled variables
variables that are kept the same throughout the entire experiment
what is physics
the science of matter, motion, energy, and force, and how they interact
what is weight, how to measure it, what units do you use
the gravitational force acting on an object, spring scale, newtons (and pounds?)
general stuff
don't eat/drink in lab, put electric materials in safe places, watch all equipment
Experimental design - what is the IV?
a factor that is purposefully changed by the experimentor
experimental design - control group
the group that doesn't receive the treatment(s) and what you compare the experimental group to
molecular structure of water
H20, in a mickey mouse format
experimental design - what is quantitative data?
experimental design - what is qualitative data?
descriptive observations, can't be given numeric value, can be described
experimental design - what is the DV
the variable that responds to change in the independent variable
experimental design - experimental group
the group that is exposed to the change in the IV
what does the structure of water molecules allow it to do?
stick together, defy gravity for a short time
