Classroom Resources: Solutions
1 – 9 of 9 Classroom Resources
Separating Mixtures, Physical Properties, Mixtures, Solute & Solvent | Middle School, Elementary School
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 | Middle School, Elementary School
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, Reaction Rate, Solute & Solvent, Physical Change | Elementary School
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.
Mixtures, Solubility, Intermolecular Forces, Polarity, Solute & Solvent, Intermolecular Forces, Molecular Geometry | High School, Middle School, Elementary School
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**
Solubility, Precipitate, Solute & Solvent | Middle School, Elementary School, High School
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!
Physical Properties, Solubility, Freezing Point, Phase Changes, Physical Change, Solute & Solvent, Freezing Point Depression, Freezing Point | Elementary School
In this lesson, students investigate how the freezing point of water changes when salt is added.
Solubility, Physical Change, Phase Changes, Reaction Rate, Solute & Solvent, Molecular Motion | Elementary School
In this lesson, students learn that particles that make up matter are in constant motion.
Observations, Chemical Change, Physical Change, Inferences, Physical Change, Identifying an Unknown, Solute & Solvent | Elementary School
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.
Separating Mixtures, Mixtures, Physical Change, Physical Change, Phase Changes, Introduction, Interdisciplinary, Distillation, Solute & Solvent, Mixture, Mixture | Elementary School
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).
