• 

  Mixtures, Melting Point, Freezing Point, Phase Changes, Freezing Point Depression | Middle School, High School

  Lab: How does Salt "Melt" Ice?

  In this lab, students will consider why salt is used to aide in snow clearing and to help keep icy roads safe. They will investigate how salt ‘melts’ ice and determine the best type of salt to do so. Additionally, students will explore the advantages and disadvantages of the various different types of salt.

  Melting Point, Covalent Bonding, Ionic Bonding, Molecular Structure | High School

  Lab: Ionic vs. Covalent Compounds

  In this lab, students will compare two seemingly similar substances, salt and sugar. Through melting a sample of each substance and analyze of their chemical composition, students will draw conclusions regarding ionic and covalent compounds.
