|---|---|---|
| Science Kit | Box with basic equipment | Experiments |
| Laboratory Apparatus | Beakers, test tubes, etc. | Practical work |
| Specimens | Preserved plants/animals | Observation |
| Collections | Rocks, leaves, insects | Classification |
D. Audio and Audio-Visual Aids
| Aid | Description | Use |
|---|---|---|
