NaCl Lattice© Teacher Resources

A valuable companion to 3D Molecular Designs’ Water Kit©, our NaCl magnetic molecules take salt crystal lessons a step further. Each ion model has 6 embedded magnets which allows students to simulate ionic bonding and demonstrate how salt cleaves off in planes. The sodium chloride lattices also help students explore the structure of salt crystals and learn about physical properties such as melting and boiling points, fragility, solubility and electrical behavior.

View magnified images of salt crystals and an explanation of the relationship between the arrangement of the ions in a typical ionic solid like sodium chloride, and its physical properties: melting point, boiling point, brittleness, solubility and electrical behavior.


NaCl Lattice© Science Activities

Your students will use magnetic sodium chloride ion models and a guided-inquiry approach to explore the properties of NaCl. They will feel the ionic bonding between sodium and chloride and learn about the postitive and negative charges of sodium and chloride, before discovering the 6:6 coordination in sodium and chloride crystal formation. From there they can explore the strength and brittleness of NaCl crystals. Additional activities can include comparing the sodium chloride model to rock salt, table salt and/or 3D Molecular Designs’ Water Kits©.

NaCl Lattice© Patterns in Crystal Structure - Math

This activity, intended for grades 3-5, uses the sodium chloride magnetic models and a guided-inquiry approach. It will help students begin to recognize multiple ways of solving a problem, practice pattern recognition, and make and test predictions. Students will examine the NaCl Lattice© and determine the number of blue and green balls in the cube. Then they will predict how many smaller cubes can be made from larger cubes, and test their predictions.
