Homogenous and Heterogeneous Solutions
Homogenous: Homogenous mixture is described using one set of properties. For example water, you would just say water, not this half of the water is brown and this half is green. So the whole quantity of water of one container has the same properties.
Heterogeneous: Heterogeneous mixture is described using more than one set of properties. For example a chocolate chip cocky has the cocky and the chocolate chips, and you can see both of them.

I think that these two videos really helped me because it thought me by giveing me examples of both of them. It also helped me understad how a set of properties can defin a mixture.
Three main types of mixtures
Solutions are mixtures made by mixing a solute and a solvent. The solute is the substance that dissolves. The solvent is the substance that does the dissolving.
Suspensions are heterogeneous mixtures of a solid and a liquid in which the solid does not dissolve. Suspensions will settle when left standing undisturbed.
Colloidal Dispersions are mixtures with characteristics part way between a solution and a suspension. Colloidal dispersions may appear homogeneous but are actually heterogeneous. Colloidal dispersions do not settle when left standing undisturbed for a period of time.

This really helped because he is actually writing everything he is saying.
Fantastic work Miona! These videos were amazing. Hopefully your classmates will watch them. Good notes and summaries on mixtures.
