Class XI Practical: Scientific Techniques - Microscope Study

Objective

To understand the parts, functions, and proper handling of dissecting and compound microscopes.

Guidelines

1. Identify Parts: Locate and name all major parts of both the dissecting and compound microscopes (e.g., eyepiece, objective lenses, stage, focus knobs, light source, diaphragm).
2. Handling: Learn the correct way to carry, place, and store the microscope.
3. Focusing: Practice focusing on a specimen at different magnifications using both coarse and fine adjustment knobs.
4. Illumination: Adjust the light intensity and diaphragm for optimal viewing.
5. Care and Maintenance: Understand basic cleaning procedures and precautions to prevent damage.

Expected Outcome

Proficiency in setting up, using, and maintaining both dissecting and compound microscopes for biological observations.
