The Scientific Method
Collecting, organizing, and analyzing experiment data.
WHat is the 4th step of the scientific method?
The center of an atom.
What is a nucleus?
These are solutions that measure lower than 7 on the pH scale
What is an acid?
Composed of only carbon, hydrogen, and oxygen these macromolecules are our main source of energy.
What are carbohydrates?
This is a type of chemical reaction that occurs in the bonding of organic molecules and involes the removal of a water molecule at the site of the bond.
What is dehydration synthesis?
Formulation of hypothesis
Two or more atoms that bond together.
What is a molecule?
Chemical substance that acts as a biological catalyst and is a type of protein.
What is an enzyme?
Composed of a glycerol molecule bonded to 3 fatty acid chains.
What is a triglyceride (fat)?
This is a process where proteins unravel and lose their unique shape and structure. An example is seen when clear liquid egg whites cook and becomes opaque, white and solid
What is denaturation?
Observation of a natural phenomenon.
What is the 1st step of the scientific method?
When a substance goes from solid to liquid or from liquid to gas.
What is a phase change?
A type of mixture where a solute is dissolved in a solvent and evenly distributed through out.
What is a solution?
Made from long chains of amino acids bonded together. These macromolecules have many diverse functions.
What is protein?
A pyrolytic process where sugar breaks down and results in a sweet nutty flavor and brown color.
What is caramelization?
Testing a hypothesis
What is the 3rd step of the scientific method.
This is the chemical formula for sodium chloride, a common food seasoning.
What is NaCl?
A type of mixture with small particles of one substances dispersed throughout another substance. (examples include foams and emulsions)
What is a colloid?
What is a monosaccharide?
A process in which starch cells are heated in water and swell and burst releasing amylopectin from within the cell. A process often used to thicken foods.
What is starch gelatinization?
Draw a conclusion from experiment data.
What is the 5th step of the scientific method?
Used to measure the relative strength of acids and bases by measuring the hydrogen ion concentration of solutions.
What is the pH scale?
A combination of two or more substances that are not chemically combined.
What is a mixture?
Fatty acids that have double bonds.
What is unsaturated fatty acid?
This process is similiar to caramelization, but requires the presence of certain amino acids as well as sugars. It results in browning and new flavor and aromatic compounds as the sugars and amino acids react with each other in the presence of heat.
What is the Maillard reaction?
