  Lesson Plan: Making Sense of Milk Mark as Favorite (1 Favorite)

  In this lesson, students will compare and contrast the chemical compositions of different types of plant milk and animal milk by analyzing data and developing models.

• 

  Freezing Point Depression, Mixtures, Phase Changes, Freezing Point, Melting Point | High School, Middle School

  Lab: How does Salt "Melt" Ice? Mark as Favorite (28 Favorites)

  In this lab, students will consider why salt is used to aide in snow clearing and to help keep icy roads safe. They will investigate how salt ‘melts’ ice and determine the best type of salt to do so. Additionally, students will explore the advantages and disadvantages of the various different types of salt.

• 

  Mixtures, Molecular Structure, Separating Mixtures, Solute & Solvent | High School

  Lesson Plan: What Type of Mixture is Paint? Mark as Favorite (7 Favorites)

  In this lesson students will use simple laboratory tests to characterize differences between solutions, colloids, and suspensions. They will then apply those tests to paints to classify them as specific types of mixtures.

• 

  Electromagnetic Spectrum, Molecular Structure, Mixtures | Middle School, High School

  Video: What are Pigments? Video Mark as Favorite (5 Favorites)

  This video discusses the chemistry of pigment molecules and how they are used to give paints their specific color. Students will learn about the importance of a pigment’s molecular structure, how they are physically suspended to create a paint color, as well as how they interact with light.

• 

  Mixtures, Solute & Solvent, Intermolecular Forces, Intermolecular Forces, Molecular Formula, Molecular Structure, Polymers, Electromagnetic Spectrum | Middle School, High School

  Video: What is Paint? Video Mark as Favorite (5 Favorites)

  This video investigates the composition of paint, while analyzing the fundamental chemistry principles of its main components. Students will learn about the differences between three common paint types, water colors, oil-based and acrylic paint as well as the chemistry of each.

• 

  Scientific Method, Observations, Inferences, Intermolecular Forces, Mixtures | High School

  Lab: Magic Milk Mark as Favorite (28 Favorites)

  In this lab, students will investigate the addition of detergent to a mixture of whole milk and food coloring. Students will attempt to explain the cause of their observations. Also, students will have the opportunity to manipulate the experiment and determine how other variables may impact the results.

• 

  Concentration, Mixtures, Interdisciplinary, Scientific Method, Measurements | Middle School, High School

  Lab: Effect of Salt Concentration on Plants Mark as Favorite (4 Favorites)

  In this lab, students will observe how salt concentration can affect the structure of a potato tuber.

• 

  Solubility, Solute & Solvent, Mixtures, Intermolecular Forces, Intermolecular Forces, Polarity, Molecular Geometry | Elementary School, Middle School, High School

  Animation: Solubility Animation Mark as Favorite (24 Favorites)

  In an animation, students will have an opportunity to visualize on the particulate level how solubility works. Examples of ionic compounds and a polar covalent compound show how when water is attracted to charged parts, they dissolve, and when they're not attracted to charged parts they stay solid. **This video has no audio**

• 

  History, Interdisciplinary, Physical Properties, Chemical Properties, Observations, Mixtures | Middle School, High School

  Lab: Top Secret Mark as Favorite (6 Favorites)

  In this lab, students will learn about the history of invisible ink and will have the opportunity to compare two types of homemade invisible ink recipes.

• 

  Intermolecular Forces, Mixtures, Intermolecular Forces | High School

  Lesson Plan: Fuel Line Antifreeze Mark as Favorite (4 Favorites)

  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, Mixture, Physical Properties, Observations | Middle School, Elementary School, High School

  Lab: Salad Dressing Science: Emulsions Mark as Favorite (9 Favorites)

  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 Mark as Favorite (9 Favorites)

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

• 

  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.
