In a nutshell: Mixtures combine substances without changing them, while solutions are mixtures where substances dissolve.
## Exploring Mixtures
A mixture is made when two or more substances are combined, but they don't change into new substances. Each part keeps its own properties.
## What Is a Solution?
A solution is a special kind of mixture where one substance dissolves in another, like salt in water.
### Separating Mixtures
Mixtures can often be separated by physical means, like filtering, sifting, or using magnets.
## Real-World Examples
- Salad is a mixture: you can pick out the tomatoes or lettuce.
- Lemonade is a solution: the sugar dissolves in water.
### Why This Matters
Knowing about mixtures and solutions helps scientists, chefs, and engineers in their work every day!
Examples
- Making a fruit salad with different fruits.
- Mixing sugar into your tea until it disappears.
