1. Course Description

Grade 10 opens on Earth and Space Science, and it opens on this country.

Grades 3 to 6 all open on materials. The four junior-high grades run the domains in a rotation — a 4 × 4 Latin square printed on page 28 of the curriculum guide — and Grade 10 is its last row: Earth and Space Science, Force/Motion/Energy, Science of Materials, Life Science. Every one of the four junior-high grades opens on a different domain, and Grade 10's is the one that begins with a map of the Philippines.

Quarter 1 is the most explicitly Filipino quarter in the whole of Key Stage 3 Science. Four of its twelve competencies name this country directly: locating its mountains, faults, volcanoes and trenches on a map and reading them as plate tectonics; predicting where the archipelago will be in 50 million years from the measured velocity of the Philippine Plate; identifying the local impacts of global climate change; and explaining how the country could make better use of its own renewable resources. Nothing here is imported context with a local example bolted on.

The rest of the year completes Key Stage 3. Quarter 2 finishes mechanics — projectiles, momentum and collisions, then how high-voltage electricity actually reaches a house. Quarter 3 is chemical reactions: indicators, types, equations, conservation of mass, and reaction rates. Quarter 4 is the last Life Science any learner meets before senior high — homeostasis, natural selection, biotechnology, and the carrying capacity of an ecosystem.

Two threads run right through, and both are about judgement rather than recall. Almost every quarter asks learners to gather from secondary sources and evaluate what they find. And Quarter 4 ends the key stage with a class debate on the ethics of biotechnology — the only competency in four years of Science that assesses a learner's ability to argue a position about the use of science rather than a fact about science itself.


2. Grade Level Standard

Quoted verbatim from the MATATAG Science Curriculum Guide (DepEd, August 2023, page 26).

Grade 10 — At the end of Grade 10, learners describe and explain the geologically dynamic nature of the Philippine archipelago in relation to its plate tectonic setting, and use models to explain the earth structures, movements, and natural events that occur. They explain mechanisms that have contributed to the current distributions of continents and make predictions about changes that can be expected in the future. Learners describe rapid changes that are occurring in local and global climate patterns and propose solutions to address these changes. Learners describe qualitatively the factors that affect the trajectory of projectiles. They distinguish different types of collisions and describe the impacts on the motion of objects. They carry out investigations using models to identify relationships that affect the motion of objects and apply their understanding to real-life situations. Learners gather information from secondary sources to identify, describe, and explain how science impacts human activities and the environment. Learners explain that there are different indicators for classifying substances as acids, bases, or salts. They describe the identifying factors for a chemical reaction as well as the important types of chemical reactions. They explain how some important chemical reactions impact the natural and built environments. They write balanced chemical equations using formula and apply the principles of conservation of mass. They explain factors that affect the rate of a reaction and that some reactions are exothermic, and others are endothermic. They demonstrate the knowledge and the skills needed to plan and conduct valid and reliable scientific investigations and record them appropriately. Learners describe homeostasis as a process that allows an organism to maintain stability. They describe and discuss that natural selection is the driving mechanism of evolutionary change. They explain the meaning of the term biotechnology and debate the societal, environmental, and ethical implications of utilizing biotechnological products and methods. They discuss the factors that limit the ecosystem's carrying capacity and the role of population growth.


3. Content Domains

3.1 The three content strands — what the learner does

Strand What it is at Grade 10
Performing scientific inquiry skills Guided investigations of momentum and of collisions using models; a valid and reliable investigation of household indicators, with dependent, independent and controlled variables identified; balancing equations against a conservation principle.
Understanding and applying scientific knowledge Plate boundaries and the mechanisms that drive them; climate change and greenhouse gases; projectiles, momentum, collisions and the electricity grid; chemical reactions, equations and rates; homeostasis, natural selection, biotechnology and carrying capacity.
Developing and demonstrating scientific attitudes and values Debating the implications of a technology. Quarter 4 competency 9 asks learners to argue the societal, environmental and ethical implications of biotechnology in class. It is the only competency in Key Stage 3 Science that assesses argument about science rather than knowledge of it.

3.2 The four discipline-oriented domains

Domain Grade 10 coverage
Earth and Space Science How plate displacement is detected and measured; the structures, movements and events at each type of plate boundary; the mountains, faults, volcanoes and trenches of this archipelago read as tectonics; predicting its position in 50 million years; what drives plate movement, including the asthenosphere; subduction's effect on the overriding plate; the Himalayas and the Andes; evidence for global warming; greenhouse gases; ENSO; local impacts and local action; renewable energy and Philippine resources.
Force, Motion, and Energy Projectile variables — angle, velocity, height, range; elastic and inelastic collisions; momentum from mass and velocity; force applied over time; seatbelts, airbags and crumple zones; conservation of momentum; generation, transmission and distribution of high-voltage electricity, substations and meters; household electrical safety; motors and generators; reducing household use; renewable against non-renewable generation.
Science of Materials Indicators that a chemical reaction has happened; acids, bases and salts identified with indicators; combination, decomposition, single and double replacement; combustion, acids on metals and carbonates, photosynthesis and respiration in the environment; word and formula equations; rearrangement of atoms and conservation of mass; balancing; rates of reaction in food preservation, fire, pollution and corrosion; exothermic and endothermic reactions.
Life Science Homeostasis and its indicators — temperature, glucose, blood pressure; positive and negative feedback; natural selection as the driving mechanism; variation, heredity, isolation, selection and adaptation; fossils, biogeography and comparative morphology as evidence; biotechnology defined; traditional fermentation — cheese, soy sauce, vinegar, nata de coco; modern biotechnology including GMOs and IVF; the class debate; carrying capacity and population growth.

3.3 One quarter, one domain — and Grade 10 completes the square

Quarter Grades 3–6 Grade 7 Grade 8 Grade 9 Grade 10
1 Materials Materials Life Force Earth and Space Science
2 Living Things Life Materials Earth Force, Motion, and Energy
3 Force, Motion, and Energy Force Earth Life Science of Materials
4 Earth and Space Earth Force Materials Life Science

Grades 7 to 10 form a 4 × 4 Latin square: read any quarter across those four grades and each domain appears exactly once, and read any grade down and each domain appears exactly once. See science-spine.md §2 and CG page 28.

Grade 10 is the row that makes the pattern visible, and it is worth showing a class. Four years, four domains, and every learner meets each domain in each position exactly once. It is not an accident and it is not arbitrary: no domain is ever the one that gets the compressed end of a school year twice running.


4. Content Map

Every entry is quoted from the official curriculum guide (DepEd, August 2023, pages 61–67), committed at docs/research/source/.

Performance tasks here are the guide's, not this syllabus's — page 17 requires at least one substantial performance task for each quarter and supplies the tasks. Grade 10 is given seven.

All 45 CG competencies are placed. None is taught twice, and none is dropped.

Quarter 3 is the lightest quarter in Key Stage 3 Science — nine competencies in seven teaching weeks, and five of those weeks carry a single competency each. That is deliberate here rather than generous: balancing equations and reaction rates are the two places in Grade 10 chemistry where a class most often runs out of practice time, and the slack is left where it is most likely to be needed. A school that does not need it has a spare week for the Quarter 2 electricity block, which is the tightest in the year.


6. Assessment and Grading

Per DO No. 015, s. 2026, for a Key Stage 3 core learning area: Written Works 20% · Performance Tasks 50% · Examinations 30%.

Transmutation is a year switch. SY 2026–2027 uses an adjusted table in which a raw 70 transmutes to a passing 75; from SY 2027–2028 transmutation is removed.

⚠️ Reported, not read. Two independent search passes returned the same split. Confirm before computing a real grade.

What Grade 10 assessment has to add

The right name for the wrong reason has to be catchable. Convergent is the correct answer to several questions in this pack and it can be produced by a learner who believes every convergent boundary makes a trench. Every boundary item in assessment.md therefore asks for the structure and the events alongside the name, and the marks are weighted there. A learner who names all three boundary types correctly and cannot say what continent-meets-continent builds has not met competency 2, which says each type.

The other Grade 10 addition is that Quarter 4 assesses an argument. Competency 9 is a class debate on the ethics of biotechnology, and a debate cannot be marked as if it were a fact recall. The rubric in §6 marks the use of evidence, the handling of the opposing case, and the separation of a scientific claim from a value claim — and explicitly does not mark which side the learner took.


7. Learner Support

Provision What it looks like
Below-level Two questions before any name. worksheet-remediation.html does not ask for a boundary name until task 2, and does not ask what forms until task 3.
On-level The standard task, naming the boundary and the structure and the events, every time.
Above-level Why do deep earthquakes get deeper inland from a trench? Why is the sea floor nowhere older than the continents? Both are beyond the competency and both follow directly from it.
Language All materials are in English. Divergent, convergent, transform, subduction, lithosphere and asthenosphere are said aloud before they are read. Note that plate in everyday English is a flat dish — and every learner pictures one. Naming that out loud on Day 1 costs ten seconds.
Learners with additional needs Enlarged print, extended time, verbal instead of written response, a peer scribe. The paper-and-books model is tactile and can be done at a desk by one learner alone. Every digital artifact is keyboard-operable and screen-reader labelled.
Absence and catch-up Every digital artifact is one file that copies to a phone or USB stick and runs offline.

8. Materials

No-cost / recycled — the default.

If available.

DepEd's Grade 10 equipment list is not held here. Quarter 1 competency 3 needs a map of the Philippine Archipelago showing mountains, faults, volcanoes and trenches, and a school without one cannot run that week as written. PHIVOLCS publishes such maps and a hand-copied outline on a board carries most of the lesson; offline-activities.md says which substitutions are honest and which are not.

What opening the guide changed

Assumed Actually
Grade 10 Quarter 1 continues Grade 9's chemistry Grade 9 ends on bonding; Grade 10 opens on plate tectonics. The two adjacent quarters share nothing.
Plate tectonics is Grade 9 Grade 9 Quarter 2 does continental drift, the Philippine plate setting and the types of boundary. Grade 10 Quarter 1 competency 2 does what happens at each of them, and competency 3 puts it on a map of this country. The two grades are a deliberate pair.
Climate change is Araling Panlipunan, or a cross-cutting theme It is five Grade 10 Quarter 1 competencies — 8 to 12 — sharing a quarter with plate tectonics.
Momentum is senior high physics Momentum, collisions and conservation are Grade 10 Quarter 2 competencies 2 to 8.
Balancing equations is Grade 9 Grade 9 writes formulae for compounds. Balancing, and the conservation of mass behind it, is Grade 10 Quarter 3 competencies 6 and 7.
Evolution is not in the K to 10 curriculum Natural selection, variation, isolation, adaptation and three lines of evidence are Grade 10 Quarter 4 competencies 3 to 5.
Each quarter has one performance task Page 17 requires at least one. Quarters 1, 2 and 3 are given two each — seven in the year.
