Comment on this resource
In this lesson, students will learn that there are limits to what the eye can see and that a magnifying glass can help extend those limits. Students may have been exposed to optical technology such as glasses, magnifying lenses, or even periscopes, microscopes, and telescopes. This lesson aims to channel the inventive energy of students to increase their awareness and purposeful use of tools. They will view objects of various sizes from several viewing distances to discover that their visual field is limited. Students will record what they see and will compare their observations with classmates in an open, nonjudgmental forum. They will have the opportunity to speculate about and experiment freely with magnifying glasses and will also conduct more structured experiments.
