All about mixtures
Unlike pure substances, mixtures are made by combining two or more different substances. A mixture can be separated out into its different parts. If you mixed sand and iron bits together on a plate, you could separate out the iron bits using a magnet because iron is magnetic. If you took different samples of this mixture, you might not get the same amount of things every time. In the first sample you may have gotten 100 grains of sand and 40 iron bits, in sample two you may get 60 iron bits and 90 grains of sand. The key point here is that mixtures are made of different things. The picture at the top of this page is a mixture because it is made up of different types of candies. Sometimes, you can't always tell if something is a mixture or not...
Heterogenous and homogenous mixtures
Their are two different types of mixtures called heterogenous and homogenous mixtures. In heterogenous mixtures you can see clearly different substances. An example of this would be a mixed fruit basket. There might be some apples, a few pears, maybe even mangos! The point is that all of these fruits are different, so a fruit basket is an example of a heterogenous mixture. An easy way to remember this is by the beginning, -hetero means 'different'.
Homogenous mixtures are the exact opposite of heterogenous mixtures! A homogenous mixture is still made up of different substances, but you can't tell by just looking at it what it is made of. Take play doh for example. When you first see the play doh, it looks like the same all through it, but when you look on the box you will find out that it is made of a whole bunch of other things. Another example of this would be sweet tea. At first glance soda is just a brown drink, but if you read the ingredient list on the side you'll see that it is not just one thing, but many! Basically, in a homogenous mixture everything in it looks the same.
