Performance Assessment

In this lab experience, students carry out a small-scale investigation to select the chemicals used in a big fireworks display. When students build atomic orbital models, they will have a visual of the probability of where the electrons reside in the atomic structure of the atom. These four labs will help you help your students understand atomic structure. Specifically, electron structure and how all elements have their own electron configuration similar to a human’s fingerprint. When students witness the various colors emitted in the flame test lab, they will understand the unique electrons in each metallic salt. Furthermore, the dry portion of the lab safely utilizes bingo chips and filter papers to model the Bohr-type atom. These models solidify that electrons reside in various energy levels. Your students are sure to appreciate the electron filling order!

Safety: Before conducting the lab, review the safety precautions on the student page with the class. Then discuss any safety precautions that are specific to your science laboratory or classroom. Good ventilation is required since burning wood splints can generate a large amount of smoke. Tie back hair and avoid loose fitting clothing. Completely extinguish wood splints before discarding.
