• 

  Solubility, Intermolecular Forces, Intermolecular Forces, Mixtures, Intramolecular Forces, Polarity, Observations, Physical Properties, Chemical Properties, Identifying an Unknown, Mixtures | High School

  Lab: Solubility & Compound Type

  In this lesson, students determine whether unknown substances are polar, nonpolar, or ionic by testing their solubilities.

• 

  Intermolecular Forces, Mixtures, Intermolecular Forces, Colligative Properties, Freezing Point Depression, Solubility, Polarity, Phase Changes, Freezing Point, Density, Mixtures, Physical Properties | High School

  Lesson Plan: Fuel Line Antifreeze

  In this lesson students will explore the role of a gasoline additive, fuel line antifreeze (generally methanol or 2‑propanol), in reducing the potential of water to block fuel lines in freezing weather. Students will prepare test tube models of water-contaminated fuel tanks and explore the effect of adding different types of fuel line antifreeze. This lesson can be used to bolster concepts about miscibility, density, intermolecular forces, phase changes (freezing), and colligative properties (freezing point depression).

  Polarity, Mixtures, Intermolecular Forces, Intermolecular Forces, Physical Properties, Observations, Mixtures | Middle School, Elementary School, High School

  Lab: Salad Dressing Science: Emulsions

  In this lab, students mix polar and nonpolar substances and then add various emulsifiers to encourage the mixing of the two substances. They use ingredients in salad dressing to relate science to real life scenarios.

• 

  Solubility, Saturated/Unsaturated/Supersaturated, Mixtures, Reaction Rate | High School

  Lab: Rate of Solution

  In this lab, students observe how particle size, solvent temperature, and agitation affect rate of solution.

• 

  Acid, Mixtures, Acid Rain, Interdisciplinary, Chemical Properties | Elementary School, Middle School

  Lesson Plan: Environmental Problems

  In this lesson, students are presented with an environmental problem to solve using important concepts of chemistry, which involves a lake with deteriorating water quality.

  Intermolecular Forces, Solubility, Intermolecular Forces, Intramolecular Forces, Polarity, Lewis Structures, Molecular Structure, Solute & Solvent, Mixtures, Melting Point, Freezing Point, Boiling Point, Physical Properties, Graphing, Mixtures | High School

  Lab: Physical Properties (High School)

  In this lesson, students investigate how intermolecular forces effect physical properties by investigating substances’ melting points as well as solubility.

• 

  Observations, Mixtures, Density, Physical Properties, Mixtures | 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.

• 

  Separating Mixtures, Density, Physical Change, Chemical Change, Mixtures, Intermolecular Forces, Intermolecular Forces | Middle School

  Lab: Clean it Up!

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

• 

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

  Lab: Candy and Leaf Chromatography

  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.

• 

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

•

  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.

• 

  Mixtures, Physical Change, Physical Change, Solute & Solvent, Phase Changes, Distillation, Introduction, Separating Mixtures, Interdisciplinary, Mixtures | Elementary School

  Lesson Plan: Now I Can Drink the Water!

• 

  Molarity, Concentration, Mixtures, Solute & Solvent, Dimensional Analysis, Mole Concept, Measurements | High School

  Lab: Molarity of a Solution

  In this lab, students calculate concentrations of and perform dilutions of Kool-Aid and juice solutions.

• 

  Density, Observations, Inferences, Mixtures, Mixtures | Middle School, High School

  Demonstration: Density Tubes

  In this demonstration, students will have the opportunity to observe and analyze the density of a solution. Students will interpret their observations as they compare the density of the solution with plastic components.
