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...

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...

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...

Putting things together in the lab is easy; sometimes, separating them is the hard part. A variety of chemical separation methods come to life in the final installment of a 10-part series. Perfect for young chemists, the video describes...

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...

In this separating mixtures worksheet, students answer 6 questions about they ways to separate mixtures including using chromatography, using skimming, and pouring off a liquid. Students are given different fractions and their properties...

Have your class look at a granite specimen and describe what they see. They should note three distinct components. Discuss mixtures with them and how they might be separated, then send them to the lab to figure out how to take apart five...

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...

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...
