The last step the instructor has led the Board with magnets come in to each group to try simulate molecules of NaCl. Using magnets instead of atoms of the element so that students see the molecular level of substances (Submicroscopic Level.)
Finally, teachers have led the board with magnets, each group tried to simulate molecules of NaCl. Instead of using a magnetic atoms so that the students can see the level of molecules. (Submicroscopic Level)
Finally the teacher with magnetic board to each group try to simulate NaCl molecules. Instead of using magnetic atoms to enable students to see the level of molecules (Submicroscopic Level).
