Classroom Resources: Solutions

26 – 32 of 32 Classroom Resources

• 

  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.

• 

  Chemical Change, Acid & Base Theories, Indicators, Solubility Rules, Gas Laws, Pressure | Middle School

  Lesson Plan: Chemistry of Pop Rocks

  In this lesson, students will determine the pH of several liquids with litmus paper or a pH probe. Next, students will explore how pH affects the production of gas with Pop Rocks. Students will also investigate how Charles’ Law affects Pop Rocks. Finally, students will design their own experiment with Pop Rocks.

• 

  Solute & Solvent, Physical Change, Solubility | Middle School, High School

  Lab: Chemistree

  In this lab, students will prepare a solution to observe a physical change.

• 

  Separating Mixtures, Interdisciplinary, Separating Mixtures, Electromagnetic Spectrum, Mixture | 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.

• 

  Solubility | High School, Middle School

  Lab: Benzoic Acid Blizzard in a Bottle

  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

  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.

• 

  Ionic Bonding, Naming Compounds, Precipitate, Ions, Molecular Formula | Middle School

  Activity: Bond with a Classmate

  In this activity, students are assigned an ion and form bonds with their classmates, recording the formula and name of the compound they created.
