  Separating Mixtures, Interdisciplinary, Separating Mixtures, Electromagnetic Spectrum, Mixture | Middle School

  Lab: Candy and Leaf Chromatography Mark as Favorite (5 Favorites)

  In this lab, students will learn that mixtures are created by the combination of two or more substances. Many colors are actually mixtures of several different pigments. Mixtures can be separated, and in this lab students will perform chromatography to separate mixtures found in candy and in leaves.

• 

  Solubility | High School, Middle School

  Lab: Benzoic Acid Blizzard in a Bottle Mark as Favorite (2 Favorites)

  In this lab, students create a snow globe by taking advantage of benzoic acid’s solubility properties in hot water.

• 

  Mixtures, Mixture, Physical Properties, Molecular Structure | Elementary School, High School, Middle School

  Demonstration: Analyzing Mixtures Mark as Favorite (11 Favorites)

  In this demonstration, the teacher will create a sequence of mixtures in a single test tube. Water, oil, food coloring and soap will be used in this demonstration to introduce the concepts of heterogeneous and homogeneous solutions as well as the idea of miscibility. Students will also have the opportunity to analyze the properties, such as surface tension of each component used.
