Diagnostic blueprint and item bank
4 diagnostic items per unit (16 total), each linked to a KCO and misconception tag.
| Item | Unit | KCO | Type | Stem | Answer key |
|---|---|---|---|---|---|
| SCI10-A-DIAG-01 | SCI10-A | SCI10-A-KCO-01 | multiple_choice | Which of the following is a pure substance? | distilled water |
| SCI10-A-DIAG-02 | SCI10-A | SCI10-A-KCO-03 | multiple_choice | What is the chemical formula for sodium chloride? | NaCl |
| SCI10-A-DIAG-03 | SCI10-A | SCI10-A-KCO-04 | short_written_response | Give two observations that suggest a chemical change occurred. | Any two of: colour change, gas produced, precipitate formed, energy/temperature change, new odour (indicating a new substance). |
| SCI10-A-DIAG-04 | SCI10-A | SCI10-A-KCO-05 | short_written_response | State the law of conservation of mass. | In a chemical reaction, mass is neither created nor destroyed; total mass of reactants equals total mass of products. |
| SCI10-B-DIAG-01 | SCI10-B | SCI10-B-KCO-01 | multiple_choice | A battery-powered flashlight mainly converts chemical energy into? | light energy (and some thermal energy) |
| SCI10-B-DIAG-02 | SCI10-B | SCI10-B-KCO-03 | numerical_response | A device takes in 500 J and outputs 125 J of useful energy. Find its efficiency. | 25% |
| SCI10-B-DIAG-03 | SCI10-B | SCI10-B-KCO-02 | short_written_response | Explain the difference between heat and temperature. | Temperature measures the average kinetic energy of particles; heat is the transfer of thermal energy between objects. |
| SCI10-B-DIAG-04 | SCI10-B | SCI10-B-KCO-03 | short_written_response | Why is no real energy system 100% efficient? | Some energy is always transformed into non-useful forms such as heat or sound. |
| SCI10-C-DIAG-01 | SCI10-C | SCI10-C-KCO-01 | multiple_choice | Which structure controls what enters and leaves a cell? | the cell membrane |
| SCI10-C-DIAG-02 | SCI10-C | SCI10-C-KCO-03 | multiple_choice | Photosynthesis mainly converts light energy into? | chemical energy stored in glucose |
| SCI10-C-DIAG-03 | SCI10-C | SCI10-C-KCO-03 | short_written_response | How are photosynthesis and cellular respiration related? | The products of one process are the reactants of the other, cycling matter and transferring energy. |
| SCI10-C-DIAG-04 | SCI10-C | SCI10-C-KCO-05 | short_written_response | Why are decomposers important in matter cycles? | They break down dead matter and return nutrients to the ecosystem so matter is reused. |
| SCI10-D-DIAG-01 | SCI10-D | SCI10-D-KCO-01 | multiple_choice | Most of Earth's energy comes from? | the Sun |
| SCI10-D-DIAG-02 | SCI10-D | SCI10-D-KCO-03 | short_written_response | Explain the difference between weather and climate. | Weather is short-term atmospheric conditions; climate is the long-term average of weather patterns. |
| SCI10-D-DIAG-03 | SCI10-D | SCI10-D-KCO-04 | short_written_response | How does convection drive wind? | Unequal heating makes warm air rise and cool air sink, producing circulation that we experience as wind. |
| SCI10-D-DIAG-04 | SCI10-D | SCI10-D-KCO-01 | multiple_choice | Why does the equator receive more solar energy than the poles? | Sunlight strikes it more directly. |
