NB G6 Science study plan

Define and correctly use 20 core ecology terms (population, community, ecosystem, biome, carrying capacity, limiting factor, producer, consumer, decomposer, food web, energy pyramid, biotic, abiotic, habitat, niche, predator, prey, symbiosis, mutualism, parasitism) with a written example for each.

Diagram three food webs from described organism lists and label each organism's role, then predict which populations would change if one producer or top predator were removed.

Explain in writing why energy decreases at each trophic level and calculate the approximate energy available at the third level when a producer level holds 10,000 units.

Compare two biomes by listing at least four abiotic factors and three representative organisms for each, and explain how those abiotic factors shape the organisms found there.

Classify ten given organism pairs as mutualism, parasitism, or competition, and justify each choice in one sentence.

Describe the roles of photosynthesis, cellular respiration, and decomposition in the carbon cycle and trace one carbon atom's path through at least four steps.

Explain how nitrogen-fixing bacteria, decomposers, and plants interact in the nitrogen cycle, using a labeled diagram.

Identify five human activities that alter ecosystem balance and predict one specific consequence of each on a named population.

Distinguish between a food chain and a food web and explain why real ecosystems rarely form simple chains.

Evaluate two short descriptions of ecosystem change and state which one shows a disruption of cycling and why.

State Newton's three laws in your own words and match each law to two real-world examples you can describe from daily life.

Calculate net force on an object given two or more forces acting in the same or opposite directions, completing at least eight practice problems with correct units.

Distinguish between speed, velocity, and acceleration, and interpret a simple distance-time graph by describing the motion in words.

Explain the difference between potential and kinetic energy and identify the energy transformations in four common devices.

Describe how friction and gravity affect the motion of a rolling object and predict how changing a surface would change the result.

Trace energy transformations through a chain of at least three devices and identify where energy is 'lost' as heat.

Define matter, mass, volume, and density, and calculate density for six given mass and volume values with correct units.

Classify ten everyday materials as conductors or insulators of heat and electricity and justify each classification.

Explain how heat transfers by conduction, convection, and radiation, giving one example of each from a home setting.

Distinguish physical changes from chemical changes across fifteen examples and state the evidence used for each decision.

Describe the particle arrangement and motion in solids, liquids, and gases, and use that model to explain why gases fill their container.

Explain conservation of mass in a closed system and predict the total mass before and after a described reaction.

Compare two unknown substances using at least four observable and measurable properties and recommend which property best separates them.

Write a testable hypothesis for three given questions and identify the independent, dependent, and controlled variables in each.

Design a fair-test procedure for a question you choose, listing materials, steps, and at least three variables held constant.

Interpret a data table and a simple graph, then write a conclusion that states whether the hypothesis was supported and cites specific numbers.

Identify sources of error in two described investigations and suggest one improvement for each.

Explain how structural adaptations in three organisms support survival in their environments, linking each structure to a specific function.

Compare at least five major groups of organisms by body structure, method of obtaining food, and reproduction, and place ten example organisms into the correct group.

Explain how classification systems use shared characteristics and why scientists revise them when new evidence appears.

Describe the layers of Earth and the rock cycle, tracing one rock through at least three transformations.

Explain how the water cycle moves water through evaporation, condensation, precipitation, and collection, and connect it to one local weather pattern.

Distinguish weather from climate and give two examples of evidence used to describe each.

Describe the relative positions and motions of Earth, the Sun, and the Moon, and explain how those motions produce day and night, seasons, and moon phases.

Explain why the Sun appears larger than other stars and compare the Sun's scale to Earth's using a written analogy.

Evaluate one technology or human activity for its benefit and its environmental cost, presenting at least two points on each side.

Complete a timed mixed review of at least 30 questions drawn from all eight domains and record the score by domain.

Identify your three weakest domains from the review and write a targeted two-week re-study list for each.
