Meteor: A meteoroid that burns as it travels through Earth's atmosphere leaving a streak of light made of hot gases
Mineral: A naturally occurring, nonliving solid with a characteristic crystal, structure and definite chemical makeup.
Mixture: A combination of two or more substances that have not combined chemically and that can be separated by physical means.
Model: An illustration, description, small reproduction, or other, representation that is used to explain an object, system, or concept.
