What is a mixture? A mixture can be easily separated. The components each keep their own properties. The proportion of components is variable. Not chemically combined

Types of Mixtures: Solution Colloid Suspension Homogeneous Particles are distributed evenly Ex: Kool-aid, Tea, Air, Salt Water Particles are dispersed throughout but are not heavy enough to settle out Ex: Jell-O, Whipped cream, Milk, Mayonnaise, Silly Putty Particles are dispersed throughout but settle out Ex: Blood, Medicine, Snow globe

Brain Check! Do you know the difference between an element, compound, and mixture? Can you differentiate between a solution, colloid, and suspension?

Around the room… Look at the different pictures around the room and identify the mixture as a solution, colloid, or suspension. Use your notes! Work quietly with a partner. Sit down when you are finished. We will go over your responses. You may study your elements foldable if you finish early.
