Types of Mixtures

Homogeneous mixtures of particles so small that they cannot be seen with a microscope and they will never settle out to the bottom of the container
Examples: vinegar, soda (unopened), and hydrogen peroxide

Homogeneous mixtures with particles that are larger than those in solution, but still boo light to settle out
Examples: Milk (water and fat), fog (water and air), cool whip, shaving cream
*Determining colloids is sometimes difficult so shining a beam of light at a colloid will make the light scatter- this scattering of light by a colloid is called the Tyndall effect
Colloids

Heterogeneous mixture containing a liquid in which visible particles settle
Examples: Italian dressing, muddy pond water, chocolate milk
Hint: If it needs shaking to mix, then it is a suspension.
Note: Suspensions will also scatter light.
