Josh here! I am going to talk about my first unit of science light.

There are two types of light artificial light and Natural light. Natural light is light produced light naturals like the sun or stars and fire or fireflies. fireflies are creatures that can use their body the make light. artificial light is light that is not natural like oil lamps or fireworks and flashlights or glow sticks. For example a flashlight is powered by a batty, which is unnatural.

It is also Luminous and nonluminous. luminous is something that produces light like some fish or glow-in-the-dark products. nonluminous is something that does not make its own light like a chair a table and a Bastet.
