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

kelvin

mass unit

lipids (hydrophobic)

v

mL, cubic cm, liter, cubic meter

length unit

meter

mass types

mg, g, kg

Length types

mm, cm, m, km

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
