When left standing, the ingredients don't separate. Once combined, the mixture is a homogeneous solution. When added to water, the liquid dishwashing soap reduces the surface tension of the solution, which makes it possible to form bubbles. In the Blowing the Best Bubbles activity, students investigate the formula for bubble solution. You can make a simple bubble solution for blowing bubbles by combining liquid dishwashing soap and water, but chemistry holds the secrets to making better bubble solutions that create larger or longer-lasting bubbles. Solutions and alloys are types of homogeneous mixtures. Lesson Plans and Activities to Teach About the Chemistry of Mixtures and Solutions Homogeneous MixturesĪ homogeneous mixture is one in which the composition of the mixture is uniform throughout. Note: for more information about the various "types" of resources available, see Understanding Science Buddies' Resources.

The resources below have been grouped as follows:Īt the bottom of this resource, you will find resources for students making solutions, dilutions, and serial dilutions a list of key vocabulary words and additional related resources. ( Note: In some of these resources, other science topics are also being taught or highlighted by the hands-on activity, but each lesson demonstrates the chemistry of certain types of mixtures as well.) As they investigate the chemistry of mixtures, they learn about hydrophobic, hydrophilic, and immiscible properties solvents and solutes solubility and saturation phases the Tyndall effect and how mixtures are related to real-world challenges and solutions. In these lessons and experiments, students learn about heterogeneous and homogeneous mixtures and explore solutions, colloids, suspensions, emulsions, and more.

The free STEM lessons and activities below all involve mixtures, combinations that do not result in a chemical change. When substances are combined, they may form a mixture, in which the individual substances retain their chemical properties, or they may form a chemical reaction, in which a new substance with its own chemical properties is created. Combining substances and exploring the chemistry behind what happens and why is science that is observable and actionable. They know that some things "mix" well and others don't and that some mixtures are permanent and others separate or dissolve after time. They may realize that blood is a mixture, as is the air we breathe. They know that beverages, paints, and glues are mixtures. Most students have a basic concept of "mixtures." They have combined ingredients in the kitchen.
