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.
