• 

  Observations, Mixtures, Density, Physical Properties, Mixture | Elementary School

  Activity: Color-Works in a Jar

  Students will be using three ingredients to create a liquid color-works mixture in a jar. This is a fun chemistry project to do with young elementary students around the 4th of July or New Year’s Eve to get the children excited about fireworks.

  Lab: Clean it Up!

  In this lab, students will consider and utilize various separation techniques to purify and reclaim used motor oil.

• 

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

  Demonstration: Analyzing Mixtures

  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.

  Mixtures, Mixture, Chemical Change, Physical Change, Observations, Density, Acid Base Reactions, Chemical Change | Elementary School

  Lab: Analyzing a Lava Lamp

  In this lab, students create a mixture of oil, water and food coloring, and then add an Alka-Seltzer tablet, to create a homemade lava lamp. Student will record their observations during each step of the process and answer follow-up questions about the chemical and physical changes that took place.

  Lesson Plan: Now I Can Drink the Water!

  In this lesson, students review important concepts of the water cycle and then design, test, and evaluate a working model of a desalination plant (a distiller).
