PNG Grade 10 Science study plan

Label a plant cell and an animal cell from memory, naming at least eight structures on each and stating one function for every structure named.

Describe diffusion, osmosis and active transport, then predict the direction of water movement for three everyday cell scenarios such as a wilted plant or a salted slug.

Sequence the pathway of blood through the heart, lungs and body, naming chambers, valves and major vessels in the correct order.

Explain how the digestive, respiratory and circulatory systems work together to deliver nutrients and oxygen, naming at least two organs from each system.

Draw and annotate a transverse section of a leaf, linking four labelled structures to photosynthesis and gas exchange.

Compare mitosis and meiosis in a table of at least six points, including chromosome number in daughter cells and where each occurs.

Solve four monohybrid cross problems using Punnett squares, stating genotype and phenotype ratios for each outcome.

Construct a food chain and a food web for a named PNG ecosystem, then explain energy loss between trophic levels using the ten per cent rule.

Classify twelve given samples as element, compound or mixture, and select a suitable separation technique for three mixtures with a stated reason.

Describe atomic structure in terms of protons, neutrons and electrons, and write electron arrangements for the first twenty elements.

Use the periodic table to state group, period, valency and metallic character for six named elements, and predict how their reactivity compares.

Write and balance at least ten chemical equations, including combustion, decomposition and neutralisation, and name the reaction type for each.

Convert between names and formulas for twelve common ionic compounds, including ones containing sulfate, nitrate, carbonate and hydroxide ions.

Describe the properties of acids, bases and salts and explain three everyday applications, one of them linked to PNG agriculture or village water treatment.

Calculate relative formula mass and percentage composition by mass for four compounds, showing every step of the arithmetic.

Explain how concentration, temperature, surface area and a catalyst change reaction rate, using particle collisions in each explanation.

Use a reactivity series to predict whether four given metal displacement reactions will occur, and justify each prediction.

Outline how lime is produced from limestone and state two uses of lime or slaked lime in PNG farming or building.

Distinguish physical from chemical change using six examples, giving the evidence that supports each classification.

Interpret a simple solubility curve and use it to explain crystallisation as a separation method.

Convert between units and record fifteen measurements using correct SI units and sensible significant figures.

Solve twelve word problems involving speed, acceleration, force, work, power, energy and efficiency, writing the formula, substitution and answer with units each time.

Draw and interpret distance-time and velocity-time graphs, extracting speed from a gradient and distance from the area under the line.

Apply Newton's three laws of motion to three PNG situations such as a braking vehicle, a canoe being pushed off a beach and a falling coconut.

Calculate pressure for three examples involving solids and liquids, and explain why a sharp tool cuts more easily than a blunt one.

Draw series and parallel circuits and calculate current, voltage and resistance in each using Ohm's law and rules for combining resistors.

Explain how an electromagnet is made and describe two uses of electromagnets in everyday devices.

Compare transverse and longitudinal waves on frequency, wavelength, amplitude and speed, and label these features on a drawn wave.

Draw ray diagrams for a concave mirror and a convex lens, and state where the image forms for two object positions.

Describe the internal structure of the Earth and link convection in the mantle to the movement of tectonic plates.

Classify twelve rock samples as igneous, sedimentary or metamorphic, and give two PNG examples of each with the process that formed them.

Explain plate tectonics and locate PNG on the Pacific Ring of Fire, linking plate boundaries to earthquake and volcanic hazards in specific provinces.

Describe the water cycle in order and explain how heavy rainfall and steep terrain in PNG increase erosion and affect soil fertility.

Distinguish weather from climate, then interpret a provided table of monthly temperature and rainfall to describe wet and dry seasons.

Describe the solar system, and explain moon phases, eclipses and the cause of seasons using labelled diagrams.

Condense each of the four domains into a single page of twelve key statements, formulas or diagrams written from memory first and corrected afterwards.

Complete two full-length practice papers of about 60 marks each under strict two-hour timing with no notes.

Rewrite every incorrect answer as a corrected explanation that names the concept that was misunderstood.

Practise six extended six-mark responses using a structure of definition, explanation, example and conclusion.

Run a final rapid-recall session of fifty mixed questions drawn from all four domains and record the score.
