Observations and Inferences
Experimental Design
Stability of Systems
Elements of Life
Organic Compounds
100
recognizing and noting some fact to gather information about the world
What is observations?
100
involves observation of events that have already happened and could not have been planned for- 9/11
What is natural experiment?
100
dynamic state in which system is stable over time (homeostasis)
What is equilibrium?
100
neither created nor destroyed but rather recycled over and over.
What is matter?
100
building blocks of life; materials making up biomolecules, which in turn make up living things
What is organic compounds?
200
made with human senses
What is qualitative reasoning?
200
conditions are deliberately altered for one variable and all other variables are held constant- pendulum
What is manipulative experiment?
200
periodic destructive events such as fire or flood
What is disturbance?
200
substances that cannot be broken down into simpler forms by ordinary chemical reactions
What is elements?
200
composed of carbon, hydrogen, and oxygen atoms; the ratio of hydrogen atoms to oxygen atoms is much higher. Also includes steroids, waxes, and fats
What is lipids?
300
empirical-- count or take measurements
What is quantitative reasoning?
300
comparing a treatment group to a control group which has not received the treatment- testing a new drug
What is controlled study?
300
ability of system to recover quickly from disturbance
What is resilience?
300
the basic building blocks of ordinary matter
What is atoms?
300
molecules composed of carbon, hydrogen, and oxygen; the ratio of hydrogen atoms to oxygen and carbon atoms is 2:1
What is carbohydrates?
400
educated guesses based on obeservations
What is inferences?
400
researcher doesn’t know which group has been treated until after the data have been analyzed- control versus experimental;bias
What is blind experiment?
400
a severe disturbance in which the system does not return to normal but instead results in significant changes in some of its state variables
What is state shift?
400
the number of protons in the nucleus of an atom, which determines the chemical properties of an element and its place in the periodic table
What is atomic number?
400
composed of amino acids, which contain carbon, hydrogen, oxygen, and nitrogen atoms
What is proteins?
500
a testable explanation for cause of an observed phenomenon
What is hypothesis?
500
neither the subject nor the researcher knows who is in the treatment group- drug testing (placebo versus experimental)
What is double-blind experiment?
500
networks of interdependent components and processes with materials and energy flowing from one component to another.
What is a system?
500
the mass of an atom of a chemical element expressed
What is atomic mass?
500
composed of smaller units called nucleotides. Each nucleotide contains a carbohydrate, a phosphate, and nitrogen
What is nucleic acids?
