Mixtures

In this separation of a mixture, students experiment with salt and sand and design an experiment to separate a mixture of the two.

Knowing an item's specific heat capacity helps determine its uses, such as a low heat capacity for a soup spoon and a high heat capacity for home insulation. Scholars find the specific heat capacity of a metal ball in the 10th...

Why does some ink bleed through paper, and other ink doesn't? Practice some paper chromatography to separate the colors from a pen with an interactive experiment for middle and high schoolers. Learners use a variety of solutions to track...

Immerse your chemistry class in solutions! They melt and compare the mixtures that make up margarine, separate black ink into its component colors, distill ocean saltwater, and practice chromatography with plant pigments. There are eight...

Discover how the periodic table tells the story of its elements. Learners begin by studying the makeup of several mixtures. Their analysis leads to a discussion of elements and the periodic table. As they dig deeper, they understand the...

Steel is an example of homogeneous mixture, also called an alloy, which is made of iron and carbon. The presentation introduces learners to elements, compounds, and mixtures. They explore their similarities and differences, and then take...

Sal introduces students to mixtures and solutions. He starts out by explaining that homogenous mixtures, such as homogenized milk, are mixtures that are even and consistent throughout. He goes on to illustrate how the particle sizes in a...

Mix it up at a party as Sam and Zoe discuss heterogeneous and homogenous mixtures and solutions. Follow this film by allowing your class to put together individual snack foods to make their own mixture!

Mixtures and solutions are different; one can be separated fairly easily and the other cannot. This hands-on experiment was written specifically for learners with visual impairments or blindness. They will use lemonade and trail mix to...

Mix things up in your physical science class by introducing mixtures. The three types are defined: suspension, colloid, and solution. It all depends on the size and type of the involved particles. With attractive animation and an...
