Let me share several resources I use to teach Periodic Trends. One of the most helpful tools is this Periodic Trends chart. I use this Chapter, which has descriptions of different periodic trends and share it with the kids. Right below are examples of Flinn’s Plotting Trends. Friendly Chemistry has this Link demonstrating how to plot periodic trends with spaghetti and homemade play dough. Friendly Chemistry placed the play dough under the copy of the periodic table. I think the spaghetti would stick just like a straw. No, I don’t think it’s a good idea to stick any play dough on the periodic table located inside the cover of your textbook.
