Although we may not think about it, chemistry is actually all around us. We don't go a day without chemistry playing some sort of role in our life...
Everything is made up of chemicals, the air we breath is made of chemicals, as are we, the Earth and the food we eat. If it weren't for chemistry then we wouldn't be alive today.
One of the most important roles of chemistry is the chemical interactions that go on in our bodies, that keep us alive: Digesting food, breathing, and thinking are all due to chemical signals and reactions taking place all of the time, without us even realising.
Your emotions are actually chemical processes that are taking place in the body, so when you are angry with someone or jealous of them, these are chemical messages travelling around your body to make you feel like this.
When you clean something, even yourself, this is to do with reactions and chemical processes when two different elements react with each other. For example when soap reacts with grease on your hands or on the dishes. All of the cleaning products that you use will contain chemicals of some kind.
Cooking contains lots of chemical reactions. These occur when food is heated or cooked, the reaction of yeast or baking powder, the use of thickening agents and many many more.
A chemical reaction you might not have thought of is why we cry when cutting onions?
In onion cells there is some sulfur, when you cut into the cells this is released into the air and a chemical reaction takes place, which again reacts with the moisture of your eyes creating sulfuric acid. This can make your eyes feel like they are burning and make them water.
