1. Performance Task Title: Time Travel Talk Show: A Journey through Atomic Models

2. Objective: Demonstrate understanding of the development of atomic models by creatively portraying the contributions of key scientists through a role-play and visual presentation.

3. Task Overview: You will form groups of 5–6 members . Each group will create a talk show or skit titled “Atomic Spotlight: Meet the Scientists Behind the Atom” , in which they will role-play as the scientists listed below and explain their atomic model. You will also create a visual representation (poster, 3D model, or digital slide) of your assigned atomic model.

4. Roles to Portray: 1. J.J. Thomson – Plum Pudding Model 2. John Dalton – Billiard Ball Model 3. Ernest Rutherford – Nuclear Model 4. Niels Bohr – Planetary Model 5. Erwin Schrödinger & Werner Heisenberg – Quantum Mechanical Model (Other students can act as host/interviewers or audience members asking questions and also assigned in other tasks.)

5. Requirements Part 1: Scripted Talk Show / Skit Each "scientist" will explain: Their model of the atom Key experiments that led to their model Strengths and limitations of their model How their model improved or replaced a previous one

6. Requirements Part 2: Visual Aid Must include a labeled diagram or 3D model of the atomic structure proposed by each scientist. Can be a poster , PowerPoint slide , infographic , or 3D physical model (e.g., clay, balls, sticks, etc ).

7. Requirements Part 3: Reflection Paper (Individual Submission, A4 bond paper) Each student will write a 1-page reflection answering: What did I learn about the evolution of atomic models? How does this help me understand modern chemistry? What part of the activity did I enjoy or find challenging?
