Oil
Oil is a type of liquid that is made up of hydrocarbons, which are molecules made of hydrogen and carbon atoms. It is found naturally beneath the Earth's surface and is extracted through the process of drilling. Oil is a valuable natural resource that is used for various purposes, including fuel for transportation, heating, and electricity generation.
Properties of Oil:
- Viscosity: Oil is thick and sticky, with a high viscosity that makes it flow slowly.
- Flammability: Oil is flammable and can be used as a fuel source.
- Insolubility: Oil does not mix with water and is insoluble in it.
- Color: Oil comes in various colors, ranging from clear to dark brown, depending on its composition.
Uses of Oil:
Oil has numerous uses in modern society, including:
- Transportation fuel for cars, airplanes, and ships
- Heating homes and buildings
- Production of electricity through oil-fired power plants
- Manufacturing of plastics, lubricants, and chemical products
Environmental Impact:
The use of oil can have significant environmental impacts, such as air and water pollution, as well as contributing to climate change through the release of greenhouse gases when burned as a fuel.

LIFE SCIENCE
From Molecules to Organisms: Structures and Processes
Create representations to explain the unique and diverse life cycles of organisms other than humans (e.g., flowering plants, frogs, butterflies), including commonalities such as birth, growth, reproduction, and death.
Unity and Diversity
Construct an argument from evidence to explain the likelihood of an organism’s ability to survive when compared to the resources in a certain habitat (e.g., freshwater organisms survive well, less well, or not at all in saltwater; desert organisms survive well, less well, or not at all in woodlands).
Create models that illustrate how organisms and their habitats make up a system in which the parts depend on each other.
