We use this activity to help quiz students on their understanding of vocab and key concepts of the atomic structure. Used as a quiz or class activity, number the vocab/ concept and then place all the vocab/concepts and answers around the room. Allow students to move around the room and try and match the term to the simple definition. Afterwards, go over the answers and see how they did. It's a great way to do a quick formative assessment of your students.
