This chapter explores the fundamental concepts of light, including its properties and behavior. It introduces key terms such as luminous and nonluminous objects, as well as the significance of transparent, translucent, and opaque materials. The chapter explains the formation of shadows, the visible spectrum of colors, and refraction, including how lenses bend light. Furthermore, it covers the anatomy of the eye, including the pupil and lens, and their role in focusing light for vision. Learn how God designed our eyes to process images through light.

Chapter 6 ‒ Light pp. 128-129 What is nearsighted vision? Does a convex lens bend light inward or outward? Do you know?
Chapter 6 ‒ Light p. 129 1. What part of the eye focuses light? the lens

Chapter 4 ‒ Forces and Machines p. 132 • We need light to see. • Light rays travel in straight lines. • Light and heat are related to each other. • The location of a light source can be determined by an object’s shadow.
Chapter 4 ‒ Forces and Machines p. 132 • The colors we see are the result of light that reflects off objects. • Some lenses are used to correct where the eye focuses an image. • God designed the parts of the eye to focus images by receiving and bending light.
