3Heterogeneous The substances are not uniformly mixed. Different substances can be seen.Example: Sand in a glass of water, cookie dough, lucky charms.
4Homogeneous Uniformly distributed (are evenly mixed) Particles are very small -- it is difficult to see each substance in the mixture.Examples: sugar and water, milk, air.Images are from
5Types of Homogeneous Mixtures Solutions – Well mixed mixtures that have the same properties throughout. (particles can’t bee seen and don’t settle over time)Examples:Colloids – well mixed mixture that has undissolved particles that will not settle over time.
