Classroom Resources: Solutions
1 – 5 of 5 Classroom Resources
Solubility, Solute & Solvent, Precipitate, Mixtures, Error Analysis, Chemical Change, Physical Change, Observations, Identifying an Unknown, Graphing | High School, Middle School
In this lab, students will test “evidence” that has been collected from a crime scene. In order to determine if the victim was poisoned, students will perform a solubility and crystallization test on an unknown powder. Then, students will attempt to identify the culprit by using paper chromatography to analyze the lipstick from the potential criminals.
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!
Precipitate, Chemistry Basics, Reactions & Stoichiometry, Solubility Rules, Balancing Equations, Chemical Change, Chemical Change | High School, Middle School
In this lab, students use solubility rules to predict which chemical reactions will produce precipitates.
Ionic Bonding, Naming Compounds, Precipitate, Ions, Molecular Formula | Middle School
In this activity, students are assigned an ion and form bonds with their classmates, recording the formula and name of the compound they created.
Balancing Equations, Conservation of Mass, Conservation of Matter, Conservation of Matter, Chemical Change, Chemical Change, Conservation of Mass, Polyatomic Ions, Precipitate | Middle School, High School
In this activity, students will learn how to count atoms and how to balance chemical equations using a simulation and games from PhET Interactive Simulations.
