- Condenser Lens: Directs light efficiently onto the specimen for enhanced visibility.
- Diaphragm: Adjusts light intensity and contrast for improved image clarity.
Mechanical Components of a Microscope
- Stage: A platform that secures and allows movement of the slide for observation.
- Stage Clips: Hold the slide firmly in place during examination to prevent movement.
- Focus Knobs: Enable fine-tuning of image clarity through coarse and fine adjustments.
Illumination System
- Light Source: Provides necessary illumination to visualize the specimen effectively.
- Light Intensity Control: Regulates brightness to optimize viewing conditions.
Frame and Base
- Arm: Connects and supports parts of the microscope for stability.
- Base: Provides stable support to prevent wobbling and enhance durability.

Scientific Skills
- Observation: Involves data collection through sensory means, both qualitative and quantitative.
- Classification: Organizing data based on shared characteristics to reveal patterns.
- Measurement: Utilizes tools for accurate quantification of variables.
- Prediction: Anticipating future outcomes based on analyzed data.
- Inference: Making logical conclusions derived from observations and data interpretation.
- Experimentation: Conducting controlled tests to establish cause-and-effect relationships.
- Communication: Clearly conveying findings and interpretations through various formats.
Variables in Experiments
- Independent Variable: The manipulated factor in an experiment to observe its effects.
- Dependent Variable: The measured outcome that responds to changes in the independent variable.
- Controlled Variables: Conditions kept constant throughout the experiment to focus on the independent variable’s effect.
