Chemistry
Study of matter, its properties, and the changes it undergoes.
Practical Applications
Chemistry in the Environment
Chemistry All Around Us
Chemistry doesn't just happen in labs—it shapes our whole environment.
Chemical Cycles
- The water cycle (evaporation, condensation, and precipitation) involves changes of state.
- Plants use photosynthesis, a chemical reaction, to turn sunlight, water, and carbon dioxide into food.
Pollution, recycling, and even the way we clean up oil spills all involve chemistry. Knowing how chemicals interact helps us protect our planet.
Examples
Using filters to remove pollutants from water uses chemical reactions.
Composting food scraps turns them into soil through decomposition.
