Grade 7 Science (NGSS-Aligned) Exam Survival Guide

Must-do topics

• Physical: atomic structure basics; chemical reactions; conservation of mass.
• Life: cells → tissues/organs; genetics (dominant/recessive traits); natural selection & adaptation.
• Earth: rock cycle, geologic time, plate tectonics; human impacts on environment.
• Engineering: testable hypotheses, controlled experiments.

Top traps

• Thinking atoms disappear in reactions.
• Dominant trait = most common (not always true).
• Earth’s plates “float on water” (they float on mantle).
• Confusing hypothesis with prediction.

Quick checks

• Balance: H₂ + O₂ → H₂O.
• Punnett square for Tt × Tt.
• Identify rock as igneous/sedimentary/metamorphic.
• Write one testable hypothesis: “If … then … because …”

You will make

• Balancing Equation Practice Cards.
• Punnett Square Chart.
• Rock Cycle Diagram.
• Mini Lab Report Template.
