Atomic Structure
Atoms are composed of these subatomic particles.
What are protons, neutrons, and electrons?
This is the name given to a bond where two atoms share an electron.
What is covalent?
This is the name of the property of water where water molecules tend to stick to other water molecules.
What is cohesion?
After you have made an observation, this is the next stage of the scientific method.
Asking a question
When presented with a new specimen, biologists must ask if it is made of these before deciding if it is living.
What are cells?
These subatomic particles are responsible for the overall charge of the nucleus.
What are protons?
This is the term given to the bond where one atom gains or loses an electron, thus changing the charge of the overall atom.
This is the name of the property of water where water molecules tend to bind to other substances.
This is the definition of hypothesis.
A possible explanation or answer to a scientific question, typically in the form of an if, then statement. NOT JUST AN EDUCATED GUESS.
This is the smallest living unit of an organism.
What is a cell?
This is the term given to an atom with the same number of protons but a changed number of neutrons, resulting in a new atomic mass.
What is an isotope?
This is the term given to an atom which has a charge.
What is an ion?
This is the name of the chemical bond that binds water molecules together.
Hydrogen Bonds
This is the term for evidence gathered from observations of experiments.
What is the difference between growth and development?
Growth = physical (size/shape/etc.)
Development = change (maturation, differentiation, etc.)
An atom is found to have an atomic mass of 9 amu, and an atomic number 4. How many electrons does it have?
Four (4)
This is the bond type that is typically found between two non-metals.
What is covalent?
A molecule with an uneven distribution of charge is known as __.
What is polar?
This is the term for a comparison group in a controlled experiment that is exposed to the same conditions as the experimental group except for one variable.
When presented with a new specimen, biologists must ask if it has a need for these two things before deciding if it is living.
Food and energy
Draw an electron configuration diagram of an atom of Magnesium.
(Separate piece of paper to be checked by teacher, should have 12 protons, 12 neutrons, 12 electrons, 3 orbitals, 2 valence electrons)
This is the type of bond found when one very electronegative oxygen has an uneven distribution of negative charge, and is attracted to the positive charge of hydrogens in other atoms.
What is a hydrogen bond?
Draw a water molecule. Label the atoms, charges, and type of bond holding them together.
(Drawing on separate sheet of paper. Should include one large negative oxygen, two small positive hydrogen, and a covalent bond.)
This is the term for a factor in a controlled experiment that is deliberately changed.
What is the independent variable?
What is the difference between evolution and change?
Evolution = population level
