Today was our first Zoom class, and while online science classes will never be my first choice, I think it went pretty well overall. I shared a print-at-home Periodic Table Battleship game (links below), which was going to be one of our activities for today, and then we talked about chemical bonds. Using supplies we had at home, we made models of oxygen and carbon atoms, with the toothpicks representing the outer electrons and then demonstrated how they can form covalent bonds (where the atoms share electrons), such as in the O2 molecule above. Then, we built sodium and chlorine so we could make NaCl with an ionic bond (where one atom gives an electron to another.) The youngest class also watched a video on spring in honor of the first day of spring. Additional ActivitiesVideos:
Bozeman Science: Chemical Bonds This video goes more into depth explaining covalent and ionic bonds for anyone who is confused by these. Ionic and Covalent Bonding example Watch as this scientist forms table salt and water from their elements! The Chemical Bonds Song For all my song lovers :) Activities: Periodic Table Battleship This is the perfect game to play over video chat, or with someone in your house. See the link for instructions and links to printable periodic tables. Look up the chemical formulas for common substances around your house (for example: water, vinegar, sugar, baking soda) and build a model for each. You can use legos, marshmallows/clay/small candies and toothpicks, or even paper or other craft supplies.
