100
What is seen or measured
What is an observation
100
Group being tested or receiving treatment
What is an experimental group
100
Nutrition, excretion, transport, respiration, growth, reproduction, regulation and synthesis
What are the functions organisms must carry out to maintain homeostasis
100
This is the movement of molecules from high concentrations to low concentrations. It is a form of passive transport
What is Diffusion
100
Carbon, Hydrogen, Oxygen and Nitrogen
What are the most common elements in living things
200
A conclusion based on observation or evidence
What is an inference
200
The "normal" group. Should be identical to the experimental group in every way except it does not receive the treatment
What is the Control Group
200
These make their own food
What are autotrophs
200
This type of transport requires the use of energy
What is active transport
200
These types of molecules are larger than their inorganic cousins, and always contain carbon and hydrogen
What are Organic Molecules, or Organic Compounds
300
An untested prediction. What you think will happen in your experiment
What is a hypothesis
300
A sugar pill or other "fake" treatment given to the control group so subjects do not know which group they are in
What is a placebo
300
This process is carried out by plants and algae to produce sugar
What is photosynthesis
300
This is the diffusion of water into, or out of a cell, across a membrane. We saw this occur under the microscope with onion skin cells
What is Osmosis
300
These large molecules are made up of a chain of many simple sugars
What are carbohydrates
400
A broad explanation of natural events that is supported by strong evidence
What is a Theory
400
Variable that is being tested to see if changing it affects something else
What is the Independent Variable
400
All life processes in an organism make up this
What is an organism's metabolism
400
This is the organelle that is responsible for producing ATP in a cell
What is the mitochondria
400
Amino acids make up this long chain molecule. DNA holds the code for making them
What is protein
500
An aspect of an experiment that can be changed. Sometimes it is held constant.
What is a Variable
500
The variable that is measured at the end of the experiment to see if it was affected by another variable
What is the dependent variable
500
This is what happens when organisms break the bonds of sugar molecules to release energy in the form of ATP
What is Respiration
500
DNA holds the code for making proteins. This is the organelle that makes it happen
What are Ribosomes
500
These chemicals affect the rates of chemical reactions. We have them in our saliva and in our stomach
What are enzymes
