In the Separation of a Mixture Chemistry Guided-Inquiry Laboratory Kit, students examine the physical properties of salt, sand, iron and stearic acid. The data are used to design and complete a process to separate the mixture of substances.
Can the components of a mixture be separated? Students discover how to separate certain mixtures in this two-part, guided-inquiry lab. A mixture is a combination of two or more pure substances. Each of these substances retains its separate chemical and physical properties. Students first examine the physical properties of salt, sand, iron and stearic acid. Then they use their collected data to design and carry out a procedure for separating a mixture of these substances. An engaging lab in which students apply concepts, such as solubility, magnetism and filtration. Teacher Notes, extensive background material and reproducible student handouts are included.
