Here is a table summarizing the Internal Assessment of Practical Work:
| Section | Details |
|---|---|
| Objective | To test the ability of candidates to make accurate observations from specimens of plants and animals. |
| Plant Life | Observations and Experiments: Permanent slides: Stages of mitosis. Diffusion: Potassium permanganate in water. Osmosis: Thistle funnel and potato osmoscope. Absorption: Using a small herbaceous plant. Transpiration: • Bell jar demonstration. • Unequal transpiration using cobalt chloride paper. • Uptake of water and rate of transpiration using Ganong’s potometer. Photosynthesis: • Necessity of light, carbon dioxide, and chlorophyll. • Release of oxygen using hydrilla/elodea. |
| Animal Life | Identification of structures: Urinary system, heart, kidney (internal structure), and brain (external view) through models/charts. Types of blood cells under a microscope. Internal structure of the ear and eye through models/charts. Endocrine glands: adrenal, pancreas, thyroid, pituitary (with models/charts). |
| Evaluation | Practical/Project Work Assessment: Evaluated by Subject Teacher (Internal Examiner) and an External Examiner. - External Examiner could be from the faculty but not teaching the subject in the relevant section. |
| Award of Marks | - Internal Examiner: 10 marks - External Examiner: 10 marks Total: 20 marks |
| Submission | Marks out of 20 are to be submitted to CISCE by the Head of the school. - Online entry of marks via CISCE’s CAREERS portal by the due date. |
