three aspects of science
Content, process, attitude
Dische diphenylamine test
DNA
dependent variable
The measurable factor; the variable that may change in response to manipulations of the independent variable.
pH paper indicator
acidic - red neutral- green basic - purple
control group
baseline for comparison but no treatment
prediction
explains what will happen if hypo is true
thmodynamic temp

mass types
mg, g, kg
Length types

Biuret
peptide bonds (amino acid are linked by peptide bonds to form proteins)
SI conversion
pico nano micro milli centi deci base unit---------- deka hecto kilo mega giga tera
experimental group
receives treatment
Benedict test and examples
reducing sugars (monosaccharides) - sucrose, glucose, ribose
theory
repeatedly confirmed by the processes of observation
pH scale
scale with values from 0 to 14, used to measure the concentration of H+ ions in a solution; a pH of 0 to 7 is acidic(many H+), a pH of 7 is neutral, and a pH of 7 to 14 is basic(more OH-)
time
second
observation
sense or extensions are used to gather info
Iodine test and examples
starch (polysacc from plants)
null hypothesis
states relationship btw indep and dep
hypothesis
testable, falsifiable, practice
independent variable
variable that is manipulated
