a solution is when one substance dissolves in another and the particles are so small that they do not filter out or deflect light, and a suspension is where the particles mix together but do not dissolve and are big enough to be filtered out and scatter light.a colloid is in between with particles that are too small too be filtered out but big enough to scatter light.(they settle out over time, however)

refer the handout that I gave on Friday.... if the particles appear to uniform throughout... that is homogeneous.... if the particle of the substance are visible... it is heterogeneous
