Objective: Children will discover how using a magnifying glass can effect what they see.‹ Return to Theme
Note: Prior to the lesson, place a variety of collected materials on each tray.
Magnifying glasses allow your eyes to see things larger than they actually are. Magnifying glasses are made with two convex lenses. Each convex lens is bent outward. The lenses take light rays and bend them so they come together at a central point. This bending of light rays makes the image appear larger than it really is. The larger image allows for more detail to be seen. This magnification is important for scientists, doctors, detectives, jewelers, artists, and other professionals to see details in very small things.
Our sense of sight is one of our five senses: touch, taste, smell, hearing, and sight. We rely heavily on our sense of sight in our everyday lives. Our eyes are kind of like a camera. They react to light and allow us to see things. The information from our eyes is sent to the brain, and the brain tells us what to do. For instance, if our eyes detect something moving quickly toward them, our brain will tell our eyes to blink and our head to turn away.
