Assessment Pack — Science 6
Term 1 · CG Quarter 1: Materials · School Year 2026–2027
A Table of Specifications, two summative tests with keys, a weekly check, and the rubrics for the four quarterly performance tasks the curriculum guide requires.
1. How assessment works this year
Per DO No. 015, s. 2026, for a Key Stage 2 core learning area:
| Component | Weight | What feeds it in Quarter 1 |
|---|---|---|
| Written Works | 20% | Weekly worksheets, weekly checks, Summative 1 and 2, investigation records |
| Performance Tasks | 50% | The Quarter 1 performance task from the guide, and the two group activities in offline-activities.md |
| Examinations | 30% | The Term 1 examination |
Half the grade is performance, and the guide sets the task — page 17 requires at least one substantial performance task for each quarter.
⚠️ The weights are reported, not read. Two independent search passes returned the same 20 / 50 / 30 split for Key Stage 2 core areas. Confirm before computing a real grade.
The rule this pack applies that Grade 5's did not
A label with no reason scores half. The competency's verb is explain why, not identify, and a marking scheme that gives full credit for the correct word teaches the class that the word is the answer. Every key below splits the mark: one for the classification, one for the evidence. This is stated on the worksheet as well, so it is not a surprise at marking time.
2. Table of Specifications
Quarter 1 · Materials · 9 competencies · 45 items across the quarter
| Quarter 1 competency | Week | Items | Cognitive demand |
|---|---|---|---|
| 1. Changes of state as diagrams and flowcharts | 1 | 5 | Understanding |
| 2. The role of heat energy | 2 | 4 | Understanding |
| 3. Why physical is reversible and chemical is not | 3 | 12 | Analysis and explanation |
| 4. Uniform and non-uniform mixtures | 4 | 4 | Understanding |
| 5. Air as a mixture | 4 | 2 | Recall |
| 6. Eight separation techniques | 5 | 8 | Application |
| 7. The benefit of each technique | 6 | 4 | Analysis |
| 8. The three features of a fair test | 7 | 3 | Application |
| 9. Three trials and accurate recording | 7 | 3 | Application |
| Total | 45 |
Twelve items for competency 3, and it is the only competency in the quarter whose verb is explain why. It is also the one competencies 6 and 7 stand on: a separation technique works precisely because the change that made the mixture was physical.
3. Summative Test 1 — Week 4
Ten items · 25 minutes · Written Works
Section A — label and reason. Each row is worth 2 marks: 1 for the label, 1 for the reason.
| # | The change | Physical or chemical | Why |
|---|---|---|---|
| 1 | Ice melting on a plate | ||
| 2 | Paper burning to ash | ||
| 3 | Salt dissolving in water | ||
| 4 | An iron nail rusting | ||
| 5 | A shirt drying on the line |
Section B — choose or explain.
- Which is not evidence that a new material was made? a. Bubbles appearing · b. The material changing shape · c. Heat given off · d. A colour change that will not wash off
- Why can you get salt back out of seawater but not flour back out of a cake? (2 marks)
- A glass shatters. Physical or chemical? Say which question you used. (2 marks)
- Blue paint and yellow paint are mixed and the result is green. Was a new material made? Explain. (2 marks)
- Name the change of state: a. liquid to gas, b. gas to liquid, c. solid to liquid, d. liquid to solid. (4 marks)
Key and marking notes
| # | Label | Reason that earns the second mark |
|---|---|---|
| 1 | Physical | Still water — freeze it and the ice returns |
| 2 | Chemical | The paper is used up; ash, smoke and gases are new materials |
| 3 | Physical | The salt is still there; evaporate the water and it comes back |
| 4 | Chemical | Rust is a different material; the iron underneath is thinner |
| 5 | Physical | The water became a gas; it is still water |
| # | Answer | Note |
|---|---|---|
| 6 | b | Shape change is the classic physical change |
| 7 | — | 2 marks. 1 for dissolving is physical, the salt is still salt; 1 for baking is chemical, there is no flour left to recover |
| 8 | — | 2 marks. Physical, and the new-material question. A learner who answers chemical scores 0 here and should be taught rather than only marked |
| 9 | — | 2 marks. No — both paints are still there, and this is why the sign is a colour change that cannot be undone or separated. A learner who says yes has the sign without its qualifier |
| 10 | — | 4 marks. evaporation · condensation · melting · freezing |
Total: 20 marks. As a percentage: marks ÷ 20 × 100.
4. Weekly Check — Week 3, Day 5
Seven items · 12 minutes · Written Works
- Why is a physical change reversible? Give the reason, not the word.
- Why is a chemical change irreversible? Give the reason, not the word.
- Give two of the four signs that a new material has been made.
- Sugar dissolves in tea. How could you get it back, and what would you lose?
- Rice is cooked. Physical or chemical? Give your evidence.
- Look at the saucer on the windowsill. What is in it, and what does that prove?
- A glass is dropped and shatters. Is that a physical change or a chemical one? Say which question you used to decide.
Key
| # | Answer |
|---|---|
| 1 | The material is still there, so it can be returned. Not "because it can be undone" — that is the same sentence twice |
| 2 | The original material has been used up and new ones exist; there is nothing to bring back |
| 3 | Any two: a colour change that will not wash off · a gas produced · heat or light given off · a solid appearing in a clear liquid |
| 4 | Evaporate the water. You lose the water |
| 5 | Chemical. Evidence: it cannot be returned to hard dry grains; drying it gives dry cooked rice |
| 6 | Salt. It proves the salt was never destroyed by dissolving — a physical change |
| 7 | See below |
About item 7
This is the item that reads. Items 1 to 6 can be answered from the wall chart and from the saucer sitting in front of the class.
| What the learner wrote | What it means |
|---|---|
| Physical — every piece is still glass | Full understanding |
| Physical — melt them down and you get glass | Better, because it names the recovery |
| Chemical — you cannot undo it | The shortcut has become the definition. Teach it on Monday |
| Physical, no reason | Half marks. The competency's verb is explain |
5. Summative Test 2 — Week 8

Key
| # | Answer | Note |
|---|---|---|
| 1 | Physical; evidence — the saucer, or evaporating the water | 2 marks, one each |
| 2 | Uniform: salt water, air, vinegar. Non-uniform: sand in water, halo-halo, soil | 2 marks |
| 3 | Oxygen, carbon dioxide, nitrogen, water vapour | 4 marks. The guide's own list in competency 5 |
| 4 | b | — |
| 5 | c | — |
| 6 | a | — |
| 7 | a | — |
| 8 | — | 3 marks. Change one factor · measure one factor · keep all other factors the same |
| 9 | — | 4 marks. Change: water temperature. Measure: time to dissolve. Same: amount of water, amount of sugar, stirring, container size — any two |
| 10 | — | So that one odd result does not decide the answer. Accept replication, or any wording about reliability |
| 11 | — | 2 marks. Physical: wax melting and re-hardening. Chemical: the wick and wax burning |
| 12 | — | 2 marks. The original material no longer exists, so there is nothing left to separate out |
Total: 26 marks.
6. Performance Task Rubrics
Four tasks, one per quarter, as page 17 of the guide requires. Every task is the guide's own.
Each rubric is 4 criteria × 4 levels = 16 marks. As a percentage: marks ÷ 16 × 100.
Levels: 4 = Full · 3 = Sufficient · 2 = Partial · 1 = Just beginning
6.1 Quarter 1 — A separation technique for a household problem, or the sugar investigation
A. Apply an appropriate separation technique to solve a local or household problem. B. Plan and conduct a simple scientific investigation involving a physical change, such as "Does sugar dissolve faster in hot or cold water?" Use your understanding of a fair test.
| Criterion | 4 — Full | 3 — Sufficient | 2 — Partial | 1 — Just beginning |
|---|---|---|---|---|
| The problem is real | A named household or local problem, with why it matters to somebody | A real problem, named | A generic problem | Invented for the task |
| The fair test | One factor changed, one measured, others named and held; at least three trials | Three features present, one trial | Two features present | The comparison has two variables in it |
| The technique fits the mixture | Correct technique, and can say why the alternatives would fail | Correct technique with a reason | Correct technique, no reason | Technique would not work |
| What was lost | States what the method costs — the water, the time, the fraction not recovered | Mentions a limitation | Claims perfect recovery | No evaluation |
6.2 Quarter 2 — The seed-and-water fair test, or a local food web
A. Apply the features of a fair test to investigate how much water is needed to grow a common garden plant from a seed. B. Select an appropriate medium to design an example of a food web in a local ecosystem.
| Criterion | 4 — Full | 3 — Sufficient | 2 — Partial | 1 — Just beginning |
|---|---|---|---|---|
| Fair test design (A) or accuracy (B) | Variables named and controlled, three or more replicates; or every organism genuinely local and correctly placed | Most controls in place; or mostly accurate | One control; or several misplacements | Uncontrolled; or organisms chosen at random |
| The four roles (B) or measurement (A) | Producers, consumers, scavengers and decomposers all present and labelled; or measurements dated with units | Three roles; or most measurements | Two roles; or estimates only | Producers and consumers only; or no data |
| Arrows or conclusion | Arrows show the direction energy travels, not who eats whom; or the conclusion points at the data | Arrows present and mostly right; or a stated conclusion | Arrows ambiguous; or a belief stated | Absent |
| Communication | A reader who was not there could follow it | Mostly clear | Needs the maker present | Not legible |
6.3 Quarter 3 — Sound-wave poster, simple-machine design, or creative writing
A. Develop an information poster explaining how musical instruments utilize the properties of sound waves. B. Design or improve a simple machine, with name, purpose, description of how it works, materials, sketch, and benefits. C. Utilize the concept of motion and gravity to write a creative story, poem, or any written art.
| Criterion | 4 — Full | 3 — Sufficient | 2 — Partial | 1 — Just beginning |

| Scientific content | Amplitude, frequency and wavelength used correctly; or the machine's force advantage explained | Terms used, mostly correctly | Terms present but decorative | Absent or wrong |
| All required parts (B) | All five parts the guide lists, each with content | Four parts | Two or three | One |
| Local usefulness | Names where it would be used and by whom | Names a use | General claim of usefulness | Absent |
| Craft | Words, diagram and layout each doing different work | Two of the three | Text only, or picture only | Not legible |
6.4 Quarter 4 — An evacuation plan, or a constellation and its cultural significance
A. Design and describe an evacuation plan for a house or school in the event of a nearby and intensifying volcanic eruption, indicating planned actions and the reasoning behind them. B. Select a constellation that can be seen from the Philippines and describe its features. Explain its practical and cultural significance for Filipino people in the past and present.
| Criterion | 4 — Full | 3 — Sufficient | 2 — Partial | 1 — Just beginning |
|---|---|---|---|---|
| Accuracy | PHIVOLCS alert levels used correctly and tied to actions; or the constellation is genuinely visible from here and correctly described | Mostly accurate | Some errors of fact | Not accurate |
| The reasoning (A) or cultural significance (B) | Every action has a stated reason; or a Filipino use is described from a named source | Most actions reasoned; or a general cultural claim | Actions listed; or the culture mentioned | Absent |
| Respect and objectivity (B) | Indigenous and scientific accounts both presented, neither dismissed | Both present, one thin | One only | Dismissive of one |
| Usability | A family could follow the plan; or a reader could find the constellation | Mostly followable | Needs the author to explain | Not usable |
6.5 The group activities
The two group activities carry their own 12-mark rubrics in
offline-activities.md. They are not repeated here.
7. What is deliberately not here
| Absent | Why |
|---|---|
| Full marks for a correct label with no reason | The competency's verb is explain why. Rewarding the label alone teaches that the label is the answer, which is the exact failure this week exists to prevent |
| Any item requiring a flame | Grade 6 does not need to light anything to understand burning. Every chemical-change example here is recalled or observed at home |
| A real ripple tank | The guide itself offers "a big tub of water or improvised ripple tank". This pack assumes the tub |
| A mark for the game | game.html is formative. Marking it would advantage learners with a device at home |
| Particle explanations | Grade 7 explains changes of state in terms of particle arrangement. Reaching for particles here answers a question nobody has asked yet, and it makes Week 3 harder rather than clearer |
