What This Lesson Teaches Best

• Explains how microscopes make tiny objects look larger so people can explore what they can’t see with eyes alone.

• Teaches how a compound microscope uses two lenses (objective lens first, then the eyepiece) to create a bigger picture.

• Describes key microscope parts and what they do (slide, stage with clips, coarse focus knob, fine focus knob, iris diaphragm).

• Introduces resolution as an important idea for seeing details clearly, not just making things bigger.

• Connects science tools to history and innovation (Robert Hooke and Micrographia, Antonie van Leeuwenhoek, and electron microscopes).

Learning Goals

• Describe what a microscope does using details from the passage.

• Explain how the objective lens and eyepiece work together in a compound microscope.

• Identify the job of the coarse focus knob and the fine focus knob when making an image look crisp.

• Explain how the iris diaphragm helps control light when viewing pale samples.

• Define resolution as the passage describes it and explain why it matters.

• Compare light microscopes and electron microscopes based on what they use to see tiny structures.

Key Vocabulary From the Text

• Objective — lens close to sample that makes the first enlarged image.

• Eyepiece — top lens you look through that enlarges the picture again.

• Diaphragm — part that controls how much light comes through.

• Resolution — how close two points can be and still look separate.

• Vacuum — space with no air where samples sit in electron microscopes.
