Mixtures

Middle school scientists compare and contrast heterogeneous and homogeneous mixtures. They differentiate solutions, colloids, and suspensions by examining samples of each. Note that the bulk of the lesson plan directs you how to...

In this solutions, suspension, and colloids worksheet, learners answer questions as it relates to their reading information about solutions, suspensions, and colloids. Students observe different examples and complete a chart as they...

Students explore density, mixture and solutions in a reaction. In this chemistry lesson, students create their own chap-stick using ingredients they analyze for their chemical contents. They discuss measuring skills, melting points and...

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...

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!

Young scholars explore mixtures and solutions. In this chemistry lesson plan, students will add different ingredients to jars in order to classify them as mixtures or solutions. There is also a nail balancing activity that can be...

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...

Learn about the classification of matter based on whether the chemical composition is pure or a mixture. Understand the definitions of elements, compounds, substances, and mixtures, and what the differences are between them. Five types...

Precipitation reactions are always interesting. How about one that forms a precipitate using a gas? Chemists of any age will enjoy this twist on a standard solubility lab. Partners observe the lack of interaction between sodium...
