  1. TutorialsLesson 4 “A Dissolving Situation”

  2. Dissolves: the physical change of a solid liquefying when added to a liquid • Mixture: a combination of two or more types of matter where each type of matter keeps its original properties and may be separated • Physical Properties: characteristics that can be observed, measured, or changed without the substance becoming a different type of matter • Solutions: the specific type of mixture where substances are dissolved in a liquid and cannot be easily separated Vocabulary

  3. A mixture is a combination of two or more substances that can be easily separated by physical means. • What are some examples of mixtures that you can think of? What is a mixture?

  4. A solution is a special type of mixture, In a solution, one substance dissolves in another substance. The dissolved particles are so small they cannot be seen even with the help of a microscope. Solutions are difficult to separate because the process often requires more time and effort. • Can you name some solutions? What is a solution?
