There are many benefits to molecules as we all use them everyday to make our lives better or easier. If you have a headache you might take some molecules like paracetamol to treat it. If you like to add sugar to your coffee or tea but don’t want the calories you can add some molecules that taste very sweet so you don’t need to add very much. If you grow plants but they attract unwanted pests you can treat them with molecules that only kill the pests but don’t harm the plant or other animals.
Molecules make up absolutely everything, so they are hugely beneficial to our daily lives in all sorts of ways. Drug molecules are designed in a way to target specific illnesses; certain molecules provide your food or drink with different flavours; colours in things like highlighter pens, fireworks or gemstones are all down to the molecules within them. Even our devices like mobile phones and televisions work the way they do because of the molecules inside them!
There are all different kinds of molecules that you benefit from, those in the air that you breathe in like Oxygen, and Nitrogen or Carbon Dioxide that you breathe out which plants love.
Molecules are everywhere! In your food ( for example, proteins, sugars, starch, fats) and drinks, including water and fizzy drinks. Can you find some more examples?
Molecules—whether occurring naturally or made by us humans—are such useful things because, by combining individual atoms together in specific ways, we end up with new entities (molecules) that can have completely different properties from the individual elements from which they are made. The library of such combinations is absolutely humongous. And we humans are literally made from many of them. Without molecules, we wouldn’t exist!
