Today students practiced ionic bonding by doing a little speed dating. Each student chose an element that was an anion or cation, designed a little person to embody that element, and recorded some basic information about the element based on its placement on the periodic table.
Students then took turns 'speed-dating' with other students by criss-crossing charges, bonding, and naming the ionic compounds they formed. Students were able to practice writing formulas, naming, when to use roman numerals, which ion goes first and more. To the right, Elijah takes advantage of Angie's height as they bond their elements.
After one round, students changed from positive to negative (or negative to positive), made another identity and then practiced bonding all over again. By working with various partners, they were able to help each other work out the problems and answer each others questions. If you look closely, you can see the girl that Kyle drew to be an anion, a negatively charged ion. His cation personality was a man wearing a tophat and a mustache.
Tomorrow students will learn and practice covalent bonding and I have a feeling that more speed-dating is in the works.
