Atoms & Molecules
The two subatomic particles that are found in the nucleus of an atom
What are protons and neutrons
What is a hypothesis?
Something given to the control group only, that is designed to be similar to what is being tested in the experimental group.
What is a placebo.
The smallest unit of matter.
What is an atom?
A living thing.
What is an organism?
A subatomic particle with a negative charge
What is an electron?
The results of an experiment are published in these types of journals.
What is peer-reviewed?
The standard international unit for mass.
What is a kilogram (kg)?
A measurement of how much mass there is per unit of volume. Often measured in g/mL
What is density?
An element found in all organic molecules.
What is carbon?
A bond formed by shared electrons.
What is a covalent bond?
An essential quality of all hypotheses.
What is falsifiable? (or what is testable)
How participants are assigned to groups in an experiment.
What is randomization?
A state of matter that can be compressed.
What is gas
Examples include fats, proteins and carbohydrates.
What are organic molecules.
A substance formed by two or more atoms covalently bonded together.
What is a molecule?
Data that is numerical, comes from measurements, and is used for statistical analysis.
What is quantitative data?
The variable that is "input" into an experiment; it is the variable that the scientists change between groups.
What is the independent variable?
Found on the periodic table, this number is the sum of the masses of the protons and neutrons in an atom.
What is the atomic mass?
Unexpected properties that emerge as biological complexity increases.
What is an emergent property?
A term that indicates the number of electrons that are found in each electron shell beyond the first.
What is an octet?
A well tested scientific concept that explains a wide range of observations.
What is a theory?
Variables that might confuse or mess up results if they are not kept the same in both groups.
What are confounding variables?
The state of matter with the least kinetic energy.
What is a solid?
A term that we use to describe the making of organic molecules.
What is synthesize?
