Mixtures

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...

How do miners isolate the substance they're looking for from a big pile of rock? Through an insightful lab, science scholars learn how to use their observation skills to identify physical properties that scientists use to separate...

What does size have to do with it? Learners analyze different mixtures, both homogeneous and heterogeneous, to discover the properties related to the size of their particles. The activity connects these properties to those of...

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 lesson of...

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...

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!

Now it becomes crystal clear why the unit is called Mixtures and Solutions. The fifth installment of a six-part unit explores mixtures and solutions. After viewing a demonstration on mixing pebbles with water, salt with water, and...

Do you separate your trail mix before eating it? Then you've been separating mixtures your whole life! Scholars model a contaminated soil sample using trail mix and estimate the percentage of each component. They consider how to clean up...

Do not pass this resource by! Everything you need to teach the property of density,and the separation of mixtures is here: an educational video, several classroom handouts, and a laboratory exercise. The video is engaging, though a...

Students observe and compare an element, compound and mixture. In this elements, compounds and mixtures lesson plan, student observe taco salad, a beaker of salt and a helium balloon. Students make lists comparing and contrasting the...
