Introduction to Chemistry - Day 1
Objective:
Introduce students to the basics of chemistry, its branches, and the scientific method while encouraging them to explore how chemistry applies to their everyday lives.
Class Activities
1. 10-Minute Launch
- Video (5 Minutes): Play an engaging video titled "What is Chemistry and Why Does it Matter?"[1] to provide an overview of chemistry, its branches (organic, inorganic, physical, analytical, biochemistry), and how it impacts daily life.
- Socratic A/B Questions (5 Minutes): Discuss in small groups:
- A: Do you think chemistry is more about discovering things we don’t know? B: Or is it more about applying what we already know to solve problems?
- A: Is chemistry more important in understanding natural processes (like how plants grow)? B: Or in creating new materials (like plastics or medicines)?
- A: Do you think chemistry is mostly about studying tiny particles we can’t see? B: Or is it more about how those particles combine and react to create the world around us?
Encourage students to share a few thoughts after each question.
3. 10-15 Minute Landing
- Group Presentations (10 Minutes): Each group presents their findings in a 2-minute presentation.
- Reflection Questions (5 Minutes):
- What surprised you about chemistry in everyday life?
- How does chemistry connect to your personal interests or future goals?
- If you could design a chemistry experiment, what would you study?
