8 weeks · About 7 hours per week
Matter and Its Interactions
Define and distinguish atoms, molecules, elements, and compounds using correct scientific vocabulary
Model the arrangement and motion of particles in solids, liquids, and gases and explain how particle motion changes with temperature
Describe how a substance's physical properties (density, melting point, conductivity) can be used to identify it
Classify changes as physical or chemical and justify each classification with evidence
Your checkpoint
A one-page concept map linking atoms, molecules, elements, compounds, states of matter, and physical vs. chemical changes, with at least 12 correctly labeled connections
Matter and Its Interactions
Explain conservation of mass by balancing simple chemical equations and counting atoms on each side
Distinguish between reactants and products and predict whether a described reaction is synthesis, decomposition, or replacement
Interpret a simple data table of mass before and after a reaction to test conservation of mass
Describe evidence that a chemical reaction has occurred (gas production, color change, temperature change, precipitate)
Your checkpoint
A worked problem set of 8 items (4 balanced equations, 4 evidence-of-reaction scenarios) with written justifications for each answer
Motion and Stability: Forces and Interactions
Calculate and compare net force from multiple forces acting along a line and state the resulting direction of motion
Distinguish balanced from unbalanced forces and predict changes in speed or direction
Apply Newton's three laws to describe everyday scenarios in writing
Interpret a distance-time graph to describe an object's speed and direction
Your checkpoint
A 10-item forces and motion problem set, including 3 graph-interpretation items, scored against an answer key with corrections noted
Motion and Stability: Forces and Interactions & Energy
Explain how mass and distance affect gravitational attraction between objects
Describe how friction and air resistance transfer energy out of a moving system
Identify kinetic and potential energy in described systems and explain energy transformations
Interpret a simple speed or motion graph to identify acceleration
Your checkpoint
A written explanation (200-300 words) of a rolling-cart scenario that identifies all forces, predicts motion, and traces energy transformations, plus a 5-item self-quiz on Newton's laws
Energy
Trace energy transformations through a multi-step system (e.g., a lamp, a car, a swinging pendulum) and label inputs and outputs
Explain that energy is conserved but can be transferred or transformed, often producing thermal energy
Distinguish conductors from insulators and explain how each affects thermal energy transfer
Evaluate a claim about a device that supposedly creates energy from nothing and explain why it is invalid
Your checkpoint
An energy transformation diagram for three systems with at least four labeled transformation steps each, plus a written rebuttal of one invalid energy claim
Waves and Their Applications in Technologies for Information Transfer & From Molecules to Organisms: Structures and Processes
Describe wave properties (amplitude, wavelength, frequency) and relate them to energy and pitch
Explain how light and sound waves behave when they reflect, refract, or are absorbed
Identify the function of major cell structures and explain how the cell membrane controls what enters and leaves a cell
Explain how body systems work together to deliver oxygen and nutrients to cells
Your checkpoint
A two-column comparison chart of wave behaviors (reflection, refraction, absorption) and a labeled cell diagram with a written function for at least six structures
Ecosystems: Interactions, Energy, and Dynamics & Heredity: Inheritance and Variation of Traits
Diagram the flow of energy through a food web and identify producers, consumers, and decomposers
Predict how removing one organism from a food web affects other populations
Distinguish inherited traits from acquired traits and explain how genes pass from parents to offspring
Describe how environmental factors and genetic variation both influence an organism's traits
Your checkpoint
A food web diagram with a written prediction of the effects of removing one organism, plus a 6-item inherited vs. acquired trait sort with explanations
Earth's Place in the Universe and Earth's Systems & Matter and Its Interactions & Motion and Stability: Forces and Interactions
Describe Earth's position and motion in the solar system and explain how this causes day, night, and seasons
Explain how Earth's surface processes (erosion, deposition, plate motion) change landforms over time
Complete a timed mixed-domain practice set and identify the two weakest domains by item analysis
Re-teach the two weakest domains using corrected notes and a short self-explanation
Your checkpoint
A 25-item timed mixed practice set with a score log, a written list of the two weakest domains, and a one-page corrected review sheet for each
Milestones
Week 2: Score at least 80% on a self-made 10-item quiz covering Domain 1 (particles, properties, physical vs. chemical changes, conservation of mass) without notes
Week 4: Correctly solve 8 of 10 net-force and Newton's-law items and correctly label acceleration on a motion graph
Week 6: Explain wave properties and cell structures from memory in a 5-minute verbal or written recap, covering at least 8 key terms accurately
Week 8: Achieve at least 75% on the 25-item mixed practice set and show a completed correction sheet for each missed item
