Marking Period 1 Quarterly Exam Review Sheet
This review sheet is to be used as a guide to help you focus your studies for the MP1 Quarterly examination.
Note: This review sheet is not intended to be all-inclusive.
Lab Skills Unit

Scientific Method- Know the steps in the scientific method (ex. Observation, Hypothesis, Conclusion…)

Be able to identify which part of the scientific method is illustrated by examples

Be familiar with the usage of basic lab tools (ex. ruler, thermometer, graduated cylinder)

Controlled experiments:
o Be able to make hypotheses, draw conclusions
o Quantitative and qualitative data – definitions/examples of each.
o Identify the experimental and control groups in an experiment and their purpose
o Identify controlled variables & their importance
o Identify independent variable(s) and dependent variable
o Be able to critique an experimental procedure
o Importance of testing ONE variable at a time

Data Tables & Graphing:
o Know how to construct & read/interpret data in a data table or graph
o Know which data goes on the axes: X (independent variable) vs. Y (dependent variable)
Unit 1A: Characteristics of Living Things

Organism = general term for a living thing

Definition of a cell

Contrast living and nonliving things

Features of Life (as discussed in class / listed in textbook) – what it means to be ‘alive’ – you don’t need
to be able to list them, but you should be able to identify and explain with examples

Growth vs. Development – be able to define and explain with examples

Define metabolism

Define cell
1

Asexual vs. sexual reproduction

Unicellular vs. multicellular (and examples of each)

Autotrophic vs. heterotrophic (and examples of each)

Importance of DNA as the genetic material of the cell

Adaptation & evolution

Homeostasis

Photosynthesis and cellular respiration
o basic definition/equation of each process
o what types of organisms do each process
o importance of ATP produced by cellular respiration
Unit 1B Intro to Ecology

Food chains & Food webs

Abiotic & biotic factors of ecosystems

Feeding strategies/trophic levels
o Producer, primary/secondary/tertiary consumer, decomposer, herbivore, carnivore, omnivore

What is the importance of decomposers in an ecosystem?

Competition

Competitive exclusion principle

Ecological Pyramids: pyramid of energy, pyramid of numbers, pyramid of biomass

In an ecosystem, matter is RECYCLED; energy flows but is not recycled (and is ultimately lost as heat)

Summarize the reactions of cellular respiration & photosynthesis, be able to recognize overall equations
for each

What is meant by the “range of tolerance” (tolerance range) of an organism for a particular
environmental condition?

Do all organisms undergo cellular respiration? Why or why not?

Do all organisms undergo photosynthesis? Why or why not?

What do plants use glucose for?

What do animals use glucose for?

How do organisms get energy? What is the ultimate source of energy for Earth’s ecosystems?

How photosynthesis and cellular respiration are interdependent and critical to the carbon/oxygen cycles

Be able to explain the 10% rule

Why lower trophic levels contain the most available energy
2

How a change in the size of the population of one organism in an ecosystem may affect another
population

Importance of decomposers in an ecosystem

Know the hierarchy (organization) of levels of the biosphere (biome, ecosystem, community, population,
species) and be able to give examples of each level

Name that biome in which Livingston is found
Unit 2A: Basic Chemistry

Definition of atom, molecule, element, compound

Basic Atomic Structure
o Compare/contrast proton, neutron, electron
o Why atoms in their elemental state are neutral
o Draw diagram of an atom showing numbers and locations of subatomic particles and energy
levels
o Be able to identify the parts of an atom, their charges, and their locations.
o Be able to draw and/or interpret Lewis dot diagrams and/or Bohr models for atoms

Periodic Table
o Atomic Mass (mass number) vs. Atomic Number
o How to determine the valence of an atom
o Be able to determine # of bonds an atom can form
o Given its atomic number, determine the number of electrons, and covalent bonds an atom will
form

Reactivity & Bonding
o What determines the reactivity of an atom? What is the importance of Valence Electrons?

Why are some atoms “stable” and “nonreactive” while others are “unstable” and
“reactive”?
o Know how covalent bonds are formed
o What determines if atoms will combine?
o # of bonds needed for C, H, O & N (the four most common elements of living things) to become
stable (HONC 1234)
→


Chemical Formulas, Equations, Reactions
o Know that in a chemical reaction, bonds in the reactant(s) are broken, atoms are rearranged, and
new bonds are formed in the product(s)
o Molecule vs. compound
o Coefficients, subscripts, arrow, reactant vs. products

Given a chemical formula with a coefficient and subscripts, determine the number of
atoms or molecules
o Understanding chemical equations, what all the symbols and numbers mean and which
substances are the reactants and products. Example: photosynthesis and cellular respiration
o Determine if an equation is balanced: Law of Conservation of Matter
o Identify the number of atoms of each element found in a formula
o Be able to draw and/or interpret a structural formula for a molecule
