Classroom Resources: Solutions
1 – 7 of 7 Classroom Resources
Solubility, Observations | Elementary School, Middle School
In this activity, students will investigate solubility by using a combination of washable markers and permanent ink to color a paper flower. The petals of the flower will be folded, and then placed in a shallow dish of water. Students will be intrigued by the outcome as they observe several changes occur. Using their knowledge of several fundamental chemistry topics, student will explain their observations using evidence and modeling.
Solubility, Solute & Solvent, Physical Change | 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, Solute & Solvent, Reaction Rate, 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.
Solubility, Solute & Solvent, Mixtures, Intermolecular Forces, Intermolecular Forces, Polarity, Molecular Geometry | Elementary School, Middle School, High School
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
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, Freezing Point, Physical Change, Physical Properties | Elementary School
In this lesson, students investigate how the freezing point of water changes when salt is added.
Solubility, Solute & Solvent, Physical Change, Molecular Motion, Phase Changes, Reaction Rate | Elementary School
In this lesson, students learn that particles that make up matter are in constant motion.
