What is a Mixture? • Mixture - two or more substances that are mixed together, but can be separated out because their atoms are not combined. • Mixture retains the properties of the substance. Example of any mixture is the cereal, Chex Mix.
Classifying Mixtures • Solvent - substance in witch another substance is dissolve. • Solute - the substance that is dissolved by another substance. Example- salt water • Solvent- water and the solute is the salt. • Solid / Solid • Solid / Liquid • Liquid / Liquid
What a Solution? • A solution is a special kind of mixture. A solution is made by mixing a solid and liquid. When solid dissolves in a liquid, the liquid is the solvent, and the solid is the solute. Solution can be separated, not by hand but with a filter, or evaporation.
Separating a Mixture • What is a mixture? • How can mixture be separated? • Mass of salt- and- water 53g • Mass of 50ml. Water 50g • Mass of the salt is 30g • Conclusion the salt-and-water solution is heavier
Observing Crystal • It looks like some of the crystal are big and some are small and is a square. A crystal is the solid form of a material that can be identified by its properties, such as shape, color, and Patten.
Separating a Mixture • Part1- Prepare the solid mixture- gravel, salt, and powder. • Part 2- Describe your plan for separating the mixture so the salt is in one cup, the gravel is in another, and the powder is an another. You pick out the gravel and then you use a screen to separate the powder and the salt and the salt will be at the top. The water will evaporation. • Part 3- The rocks is on the screen. The powder is on the filter and the water and salt is in the cup. • Google. COM
SALT SOLUTION How can we find out what might happen if you keep adding water? Solubility- is the property that substance have of dissolving in solvents. Solubility is different for different materials and can change with temperature and different solvents. Measure 50ml water into a cup. Add salt one spoon at a time. Count as you add.
How to Separate Mixtures and Solutions into its Parts • Picking • Sifting • Magnetism • Evaporation • Filtering
Goals • To understand facts about Mixtures and Solutions • To learn about Mixtures and Solution, but also to have fun. • Also to learn what you should learn in 5th Grade.
