Objective
By the end of this lesson, you will understand the importance of chemical reactions in the production of various substances and how society influences the development of new materials.
Materials and Prep
Materials needed: pen, paper, internet access
No prior knowledge required, just come with an open mind and curiosity!
Activities
1. Research and present: Choose a substance (e.g. plastic, medicine) and research its production process, focusing on the chemical reactions involved. Create a short presentation to share with the class.
2. Experiment time: Conduct a simple chemical reaction experiment using household items (e.g. baking soda and vinegar) and observe the changes that occur. Document your observations.
3. Historical perspective: Explore how societal needs and advancements have influenced the development of new materials throughout history. Create a timeline to showcase key milestones.
Talking Points
- Chemical reactions: "Chemical reactions are like recipes for making new substances. Just like mixing ingredients to bake a cake, different chemicals combine to form something new."
- Everyday examples: "Think about the shampoo you use or the plastic in your phone - all made through chemical reactions. It's fascinating how science impacts our daily lives!"
- Society's impact: "Did you know that societal needs drive the creation of new materials? For example, the demand for sustainable products has led to the development of eco-friendly materials."
- Innovation: "Scientists and engineers work together to create new materials that benefit society. It's like a puzzle where they need to find the right pieces to solve real-world problems."
