This activity has students exploring the atomic models and energy level "status" of a number of different elements. Using small beads, which can be found at any arts/crafts store for a very small amount of money, students will "map out" the orbital diagrams (using a Bohr model scheme) in a race against time! Prior to timing themselves, students will engage in some atomic structure review.
Note that this activity has the potential to result in beads rolling everywhere. Keeping the beads in a cup, and/or putting barriers around the stations where students will engage in this, will make it easier for clean up afterwards.
The orbital diagrams referred to in this activity are not included but can be easily be drawn. You'll want three circles around a nucleus, to represent the first three energy levels. Also, note that you control the number of beads you provide to students. You can build more structure into the experience by providing a set number of beads that will result in only seven elements being possible to model (or, flip it the other way and provide as much freedom as you like within the first three energy levels). Finally, you'll want to personalize the activity in the highlighted spots!
Feel free to contact me for more information! This activity would support development towards meeting performance expectation MS-PS1-1 of the Next Generation Science Standards.
