Welcome the students, introduce the title of the lesson, and set the stage for exploring how small decisions can create big ripples. Mention that today's focus will be on understanding the Butterfly Effect in decision making.

Explain the concept of the Butterfly Effect in simple terms. Use visual metaphors like a butterfly fluttering its wings leading to a storm, to illustrate cause and effect in complex systems.

Discuss several examples that illustrate the concept in everyday life, such as personal decisions, environmental actions, and historical events. Engage the class with questions to stimulate thinking about small decisions and their outcomes.

Facilitate an interactive discussion with the students. Ask guiding questions like: "Can you think of a time when a small decision you made ended up having a big consequence?" Encourage students to share their experiences.

Summarize the key points from the lesson. Emphasize that recognizing the limits of small actions can lead to better decision-making. Invite students to reflect on how they might apply these ideas to their own lives.
