Classroom Resources: Solutions
1 – 6 of 6 Classroom Resources
Solubility, Physical Change, Solute & Solvent | Elementary School
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.
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 | Elementary School, Middle School, High 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, Saturated/Unsaturated/Supersaturated | Elementary School, Middle 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.
