How fast light travels

Science

• The child has learned that light travels at a very fast speed of approximately 299,792 kilometers per second.
• They have learned that light travels in straight lines called rays, and can be reflected or refracted.
• The child has understood that light travels faster than sound, which is why we see lightning before we hear thunder.
• They have learned that light can be absorbed by certain materials, such as dark colors, and reflected by others, like mirrors.

For continued development, the child can conduct experiments to explore the properties of light further. They can create a prism using a glass of water and observe how light is refracted into different colors. They can also investigate how different materials affect the reflection and absorption of light by conducting experiments with different surfaces and colors. Additionally, they can research the concept of the speed of light in different mediums, such as air, water, or glass, and explore how it affects the path of light.
