Mixing two or more substances may result in pretty cool things. In this video, Jessi will explain as well as demonstrate the two main types of mixture — suspension and solution. Suspensions are formed when two substances form a mixture from which they can be separated once we discontinue stirring. For instance, a mixture of water and sand can be easily unmixed using some separation technique, such as filtration. On the other hand, a solution is formed when the substances are evenly distributed and cannot be unmixed. Water/sugar and food color/water are some of the examples of such mixtures. The key difference between a suspension and a solution is that while the former can be unmixed, the latter cannot be unmixed.
This video satisfies the 5-PS1-4 requirement of fifth-grade science proficiency.
Students who demonstrate understanding can: 5-PS1-4. Conduct an investigation to determine whether the mixing of two or more substances results in new substances.
