Based on the provided text, here are some key points about this activity:

1. Duration: This activity is designed for three class periods.

2. Homework Assignments:

- Students will read an online Science News article and answer questions before the first class.

- For homework after the second class, students will work individually or in groups to create a 2-D or 3-D physical model of their group's chosen classic atomic model.

3. Class Structure:

Day 1:

- Students research and prepare presentations about different models of the atom that show how physicists' understanding of atomic structure evolved over time.

Day 2:

- Teachers will discuss the standard model of particle physics with students, followed by a brainstorming session where students think up ways to create either a 2-D or 3-D interpretation of it.

- Students can finalize their physical models and make presentations to the rest of the class.

Day 3 (Final Session):

- Teachers will discuss the standard model of particle physics with students again, asking them to brainstorm ideas for creating two- or three-dimensional representations.

4. Resources:

- CERN: The Standard Model is suggested as a resource that teachers can use during lessons about particle physics and atomic structure.

5. Learning Objectives:

1. Students will understand how scientists' understanding of the atom has evolved over time.

2. They should be able to describe different models of the atom, their strengths and weaknesses, and why they were eventually replaced by more accurate theories such as quantum mechanics or relativity.

6. Skills Developed:

- Critical thinking: Students will need to critically evaluate evidence from scientific sources in order for themascopeofknowledgeaboutatomicstructurewith peersandexperts alike; analytical reasoning skills are also required when interpreting data presented within these various models of atoms.

2. Problem-solving abilities: By working together as groups, students can develop problem-solving strategies while creating presentations and physical models about different atomic theories.

7. Collaboration:

- Throughout the activity, students will work in small groups to complete tasks such as researching classic atomic models, preparing presentations, and brainstorming ideas for representing particle physics concepts graphically or three dimensionally.
