#16 Separation Science Lab
Learners in this inquiry-based experiment, put in the role of a method development chemist. The scenario they are given is that a train wreck has occurred resulting in a chemical spill. Students are told that the spill mixture consists...
Curated OER
Mixture Mayhem
In this mixture worksheet, students are given five mixtures and they determine if each is a mechanical mixture or a solution. They also identify the way each substance within the mixture can be separated from the others.
Curated OER
In the Mix
Students construct a water filter. In this engineering lesson, students discover how to construct a water filtration system. Students work in groups to sort tools by their properties. Students analyze and construct a water filtration...

Filter It!
Elementary schoolers who are learning about filtration and mixtures could use this instructional activity to gain practice in filtering techniques. In it, they are asked how to manipulate a container in a way that would lead to properly...
Curated OER
Mixtures
Students differentiate the two types of mixtures. In this chemistry lesson, students create their own mixture and classify them according to their type. They simulate steel production with the help of a guest speaker.

Mixtures
In this mixtures worksheet, students fill in 7 blanks, determine if 4 statements are true or false, match 7 terms with the appropriate definitions, and solve 2 problems. These include topics such as homogeneous and heterogeneous...
Curated OER
Mixtures are Exciting
Fifth graders collaborate with other classmates to classify and create mixtures made of two or more substances. In this mixture lesson, 5th graders create solid-solid, liquid-solid, and liquid-liquid mixtures. Students discuss with the...
Curated OER
What Are Mixtures And Solutions?
Students explore mixtures and solutions. For 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 done at home.
Curated OER
I'm All Mixed Up
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...
Curated OER
Structure of Matter
Fifth graders, in groups, distinguish between mixtures, solutions and suspensions.
Curated OER
Chromatography
Students study about chromatography, a process used to separate mixtures.
