• The teacher circulates around the room, providing guidance and answering any questions that might arise.

2. Step Two: Timeline Creation (10 - 12 minutes)

• After analyzing the events, each group creates a timeline of Atomic Evolution on their construction paper. They should include the significant events and any additional information they found relevant.

• The teacher encourages creativity and provides suggestions for how groups can visually represent the different stages of Atomic Evolution.

3. Step Three: Presentation (5 - 6 minutes)

• Each group presents their timeline to the class, explaining the events they included and how these events contributed to Atomic Evolution.

• The teacher facilitates the presentations, providing feedback and encouraging questions from other students.

Activity 2: "Atom's Journey Board Game"

• The teacher introduces a board game activity where students will act as atoms and navigate through different stages of Atomic Evolution. The game will help reinforce their understanding of Atomic Evolution and encourage collaborative learning.

1. Step One: Game Setup (5 - 7 minutes)

• The teacher provides each group with a board game set that includes a game board, game pieces, dice, and challenge cards. The game board represents the different stages of Atomic Evolution, from the Big Bang to the development of life on Earth.

2. Step Two: Game Play (10 - 12 minutes)

• One student from each group starts as the "atom" and rolls the dice to move on the board. When landing on a stage, the student picks up a challenge card that includes a question or a task related to that stage. The student must answer the question or complete the task correctly to move forward.

• The rest of the group members act as the "scientists" and can help the "atom" answer the questions or complete the tasks. This encourages group collaboration and discussion.

3. Step Three: Winning Criteria (5 - 6 minutes)

• The first "atom" to reach the last stage of Atomic Evolution and answer the last challenge card correctly wins the game. The teacher can provide a small, symbolic prize for the winning group to make the activity more exciting.
