Day 29 – Bohr Diagrams


Science 9 – Students started learning how to do draw Bohr Diagrams today.  When doing them for ions, the students sometimes get confused on calculating the correct number of electrons. I broke out my Math Cubes to help with this, and they quickly help students get past this hurdle.  They place down the number of cubes = # of protons and then pair them off with electrons (a different colour of cube) until the number of extra cubes is equal to the ion charge.  Even writing this, it sounds a bit weird or strange, but actually doing it makes the visual representation really clear.
