• 

  Solute & Solvent, Mixtures | Elementary School

  Demonstration: Introduction to Solutions Mark as Favorite (5 Favorites)

  In this demonstration, students will recognize that there is a threshold for the amount of salt that can be dissolved into a specified amount of water. Students will be asked to make observations about two different salt water samples to determine if a sample that contains undissolved salt is still considered a solution. The saltiness, or salinity, of the water samples will be used to help students make connections about how the melting of polar ice caps is changing the average salinity of the ocean.

  Solubility, Solute & Solvent, Physical Change | Elementary School

  Demonstration: Crystallization of Sugar Mark as Favorite (5 Favorites)

  In this demonstration, students will observe how to make rock candy in order to understand how sugar crystals form. They will be able to explain what a supersaturated solution is and how it is relevant to sugar crystallization.

• 

  Separating Mixtures, Physical Properties, Mixtures, Solute & Solvent | Elementary School, Middle School

  Lab: What Does Ironman Eat for Breakfast? Mark as Favorite (12 Favorites)

  In this lab students will compare and contrast mixtures and solutions. They will be tasked with extracting iron from various breakfast cereals. They will then conclude which cereal would be the healthiest for Iron Man to eat for breakfast.

• 

  Concentration, Solute & Solvent, Chemical Change | Elementary School, Middle School

  Demonstration: Soft Eggs Mark as Favorite (2 Favorites)

  In this demonstration, students will first observe a reaction between vinegar (acetic acid) and an egg shell (calcium carbonate) to produce a naked egg. Using these eggs, student will analyze how certain substances can move through a membrane and also determine if the membrane is affected.

• 

  Solubility, Solute & Solvent, Reaction Rate | Elementary School

  Lab: M&M's Solution Mark as Favorite (2 Favorites)

  In this lab, students will investigate dissolving using M&M’s and will determine whether dissolving happens faster without assistance, or with the assistance of the tongue and teeth.

• 

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

  Animation: Solubility Animation Mark as Favorite (78 Favorites)

  This animation explores how ionic and molecular compounds dissolve (or don’t) in water. Students will see that if an ionic compound such as salt dissolves, the ions dissociate, whereas the molecules in a molecular compound such as sugar remain intact but are separated from one another by water molecules. They will also see that some ionic compounds such as chalk do not dissolve, and the cations and anions remain stuck together. **This video has no audio**

• 

  Solubility, Solute & Solvent, Precipitate, Saturated/Unsaturated/Supersaturated | High School, Elementary School, Middle School

  Lab: Winter Crystals Mark as Favorite (45 Favorites)

  In this lab, students will create a supersaturated solution by dissolving borax in boiling water. They will create a snowflake using pipe cleaner to suspend in the solution, which will serve as a nucleation site for crystallization as the solution cools and remains undistributed overnight. This lab gives students an opportunity to experience the exciting crystallization process and become more familiar with an engaging chemistry spectacle!

• 

  Freezing Point, Solubility, Solute & Solvent, Phase Changes, Freezing Point Depression, Physical Change, Physical Properties | Elementary School

  Lesson Plan: Salting Roads in Winter Mark as Favorite (3 Favorites)

  In this lesson, students investigate how the freezing point of water changes when salt is added.

• 

  Solubility, Solute & Solvent, Molecular Motion, Phase Changes, Reaction Rate | Elementary School

  Lesson Plan: Particles in Motion Mark as Favorite (1 Favorite)

  In this lesson, students learn that particles that make up matter are in constant motion.

• 

  Chemical Change, Solute & Solvent, Observations, Inferences, Physical Change, Identifying an Unknown | Elementary School

  Lesson Plan: Alien Invasion? Mark as Favorite (2 Favorites)

  In this lesson, students will explore both physical and chemical changes as they try to help the Department of Homeland Security analyze and identify materials found in a mysterious capsule. Students will examine and observe an unknown object (a frozen water balloon) as it changes (melts). They then mix combinations of everyday substances to observe chemical changes.

• 

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

  Lesson Plan: Now I Can Drink the Water! Mark as Favorite (3 Favorites)

  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).
