GA Milestones Science Grade 8 study plan

Map every Science domain topic listed in the Georgia Grade 8 standards into a personal checklist, marking each as mastered, shaky, or unknown.

Define and correctly apply the core vocabulary of matter and energy: atom, element, compound, mixture, pure substance, and conservation of mass.

Distinguish physical changes from chemical changes using evidence such as new substance formation, gas production, and energy release or absorption.

Interpret simple particle diagrams to classify a sample as an element, compound, or mixture.

Balance simple chemical equations and explain why mass is conserved in a closed system.

Identify the reactants and products in a described reaction and classify it as synthesis, decomposition, or a simple replacement pattern.

Explain how temperature and particle motion relate to changes of state, including melting, boiling, condensation, and sublimation.

Compare conduction, convection, and radiation and give one everyday example of each.

Describe the structure of the atom, including protons, neutrons, electrons, and the location and charge of each.

Use the periodic table to determine atomic number, mass number, and the number of each subatomic particle for a neutral atom.

Explain how elements in the same group share chemical properties and identify metals, nonmetals, and metalloids on the table.

Distinguish ionic from covalent bonding in terms of electron transfer versus sharing.

Trace the path of energy through a food web and distinguish producers, consumers, and decomposers.

Explain photosynthesis and cellular respiration as complementary processes and state the inputs and outputs of each.

Predict the effect of removing or adding one organism to a food web.

Describe how energy is lost at each trophic level and why food chains are limited in length.

Compare the characteristics of the major biomes and explain how climate determines which biome forms.

Identify adaptations that help organisms survive in a specific environment and explain the advantage each provides.

Distinguish natural selection from individual change and give an example of an inherited versus an acquired trait.

Use evidence such as fossils or anatomical similarities to explain a simple evolutionary relationship.

Explain the role of the sun, gravity, and orbital motion in the solar system and distinguish rotation from revolution.

Describe how the tilt of Earth's axis causes seasons and how moon phases and eclipses arise from relative positions.

Compare the properties of inner and outer planets and relate distance from the sun to temperature and orbital period.

Identify the layers of Earth and explain one piece of evidence for plate motion such as seafloor spreading or earthquake patterns.

Design a controlled experiment by identifying the independent variable, dependent variable, and at least two constants.

Write a testable hypothesis and distinguish it from a prediction or an observation.

Interpret a data table or graph to state a trend and identify an outlier.

Explain why repeated trials and a control group increase confidence in a conclusion.

Take one full-length timed practice test under exam conditions and record the raw score.

Categorize every missed question by topic and identify the three weakest areas.

Re-teach each weak area using your own notes and complete five targeted practice items per area.

Build a final one-page summary sheet of the highest-risk facts and formulas.
