Mixtures+and+Solutions

=Mixtures and Solutions Overview= Chemistry is the study of the structure of matter and the changes or transformations that take place in it. Learning about the makeup of substances gives us knowledge about how things go together and how they can be taken apart. Learning about changes in substances is important for several reasons: changes can be controlled to produce new materials; changes can be used to give off energy to run machines. The **Mixtures and Solutions Module** has four investigations that introduce students to these fundamental ideas in chemistry.

=Objectives= • Gain experience with the concepts of mixture and solution. • Gain experience with the concepts of concentration and saturation. • Gain experience with the concept of chemical reaction. • Apply an operational definition to determine the relative concentrations of solutions. • Use group problem-solving techniques to plan investigations. • Use measurement in the context of scientific investigations. • Apply mathematics in the context of science. • Acquire vocabulary associated with chemistry and the periodic table. • Be introduced to the concept that all matter is made of very small particles called atoms and that atoms combine to form molecules. • Use scientific thinking processes to conduct investigations and build explanations: observing, communicating, comparing, organizing, and relating.



Audio stories for mixtures and solutions

=Big Ideas= • A mixture combines two or more materials that retain their own properties. • A solution forms when a material dissolves in a liquid (solvent) and cannot be retrieved with a filter. • Evaporation can separate a liquid from a solid in a solution. • The solid material separated by evaporation from a solution forms distinctive patterns.
 * Investigation 1**

• Solubility is the property that substances have of dissolving in solvents. Solubility is different for different materials and can change with temperature and different solvents. • A solution is saturated when as much solid material as possible has dissolved in the liquid. • When equal volumes of two solutions made from the same ingredients are compared, the heavier one is the more concentrated solution.
 * Investigation 2**

• Concentration expresses a relationship between the amount of dissolved material and the volume of solvent. • The more material dissolved in a liquid, the more concentrated the solution. • A concentrated solution can be made more dilute by adding solvent to the solution.
 * Investigation 3**

• When a change results from mixing two or more materials, that change is a chemical reaction. A reaction results in new materials. • Formation of a gas is one change that occurs in some reactions. • Formation of a precipitate occurs in some chemical reactions. • Not all chemicals react when they are mixed.
 * Investigation 4**
