Erosion Patterns
Students explore erosion when there are multiple types of sediments. They view a soil separation demonstration jar before and after agitation to determine how and why the layers settled. In addition, they conduct experiments with a river...

The Chemistry of Refining Crude Oil
Consider our energy sources: wood, coal, oil, uranium. Learners compare the pollution to energy produced for each. They practice fractional distillation of an alcohol/water mixture to simulate the process of refining crude oil....

Mixtures
In this mixtures pre-lab worksheet, students compare and contrast suspensions and colloids and solutions and colloids. Students describe the Tyndall effect. This worksheet has 10 short answer questions.
Curated OER
Solutions, Suspensions, and Colloids
In this solutions, suspension, and colloids worksheet, middle schoolers answer questions as it relates to their reading information about solutions, suspensions, and colloids. Students observe different examples and complete a chart as...
Curated OER
Powder
Young scholars investigate several unidentified substances and suggest a use of each substance. They can explain that a substance has characteristic properties, such as density, a boiling point, and solubility, all of which are...
Curated OER
Paper Chromatography
Students participate in an experiment determining how to separate a mixture of dyes in water-soluble ink.
Curated OER
T-Shirt Chromatography
Students study about chromatography, a process used to separate mixtures. They see that chromatography is used to detect, separate or purify different substances. This nice lesson results in a beautiful t-shirt for each student!
Curated OER
Solutions
In this solutions learning exercise, students read about solutions, solutes, and solvents. Students compare solutions with mixtures that are not solutions. Then students complete 10 fill in the blank, 12 matching questions, and 10 terms...
Curated OER
Rainbow Electrophoresis Lab
Students are introduced to the principles of gel electrophoresis. They practice loading gels and pipetting. In this laboratory activity, food color is separated into constituent pigments. The lab can be run with standard electrophoresis...
Curated OER
Paper Chromatography
Students investigate the pigments in Magic Markers using chromatography. In this paper chromatography lesson plan, students use absorbent paper and mark the strip with a Magic Marker. They place the strip in a solvent and observe the...
Curated OER
Chromotography
In this chromatography worksheet, students are given markers, filter paper and a solvent to separate the pigments found in each marker. Students create a chromatogram for each marker.

Acids, Bases and Solutions
If you are not part of the solution, then you are part of the precipitate. The presentation covers solutions, suspensions, solubility, dissociation, and acid/base reactions. This is the 19th lesson in a series of 26.
Curated OER
Paper Chromatography
Students use this design the illustrate how ink can be separated into its component chemicals using paper chromatography. They use five unknown samples of ink on pre-labeled chromatography strips are provided to students. Students use...
Curated OER
Oil Spill
Pupils use one of four absorbent products to separate as much of the oil and water mixture they are able to do. The purpose of this task is for students to collect and analyze data for the purpose of determining which absorbent is best,...
Curated OER
T-shirt Chromatography
Students explore chromatography, a process used to separate mixtures. They create a colorful T-shirt design.
Curated OER
Chlorophyll
Students use thin layer chromatography, TLC, to separate various pigments found in plants.
Curated OER
Rainbow Electrophoresis
Students are introduced to the principles of gel electrophoresis and also provides an opportunity for students to practice loading gels and prpetting. In this laboratory activity, food color is used to separate into constituent pigments.

Build and Engineer an Underground Mine
Students answer questions on a worksheet about mineral processing, iron fillings, and how to safely manage the left over material after separated. This is really not a lesson plan, just a worksheet that is filled out following the making...
Curated OER
Flotation
Students examine how one of the ways the mining companies extract coal is through the flotation method where air bubbles float coal particles to the top of a solution. The coal is scooped off and separated. They participate in the...
Curated OER
What's In Crude Oil?
Students investigate crude oil. In this crude oil lesson, students investigate fractional distillation and use this technique to separate two liquids.
Curated OER
Build an Electrophoresis Chamber
Students explore electrophoresis, a technique used to isolate DNA. They assemble a gel chamber for separating mixtures. Students observe separation influenced by electric charge. They define separation through gel electrophoresis.
