Activity #29- Physical Properties of Mixtures Create a chart in your notebook as seen below. Mixtures Homogeneous Mixtures Heterogeneou s Mixtures

Mixtures Definition: Two or more substances that are combined together, but not chemically joined. Can be separated by physical properties: EX: Size, Density, Solubility, Electrical Charge, Magnets, Filtration, Evaporation Mixtures can be homogeneous or heterogeneous.

Homogeneous vs. Heterogeneous Homogeneous- particles evenly spread throughout entire mixture (has uniform composition). Ex: Sugar water, air, soft drinks Heterogeneous- particles not evenly distributed throughout entire mixture (does not have uniform composition) Examples: fruit salad, soil, trail mix

Homogeneous vs. Heterogeneous

Homogenous vs. Heterogeneous 1.Number 1-9 in your notebook (add this to activity 29) 2.You will receive a numbered beaker. Write down the substance name, and then identify it as a heterogeneous or homogeneous mixture. 3.We will rotate each beaker, and you will have 30 seconds to record your responses.

Homogeneous vs. Heterogeneous 1.Oil and Water 2.Salt and Water 3.Dirt and Water 4.Food coloring and water 5.Powerade 6.Dirt and Iron Filings 7.Salt and Pepper 8.Coffee 9.Pepper and Iron Filings
