Contextualization illustrates the significance and prevalence of organic reactions in everyday life, sparking greater interest in the topic.

Situasi Berbasis Masalah

1. Think about the synthesis reaction of acetylsalicylic acid, which is the active ingredient in aspirin, from salicylic acid. What reactants would you need, and what would be the final product? Discuss the intermediate steps involved.

2. Imagine you're a researcher needing to come up with a new way to produce biodiesel from vegetable oils. What reactants and conditions are necessary for this reaction to be efficient? How could knowledge of catalysts help improve the yield of the reaction?

Kontekstualisasi

Organic reactions are crucial in both nature and industry. They play a role in biological processes like protein synthesis and metabolite production, and are essential for manufacturing chemicals, pharmaceuticals, and materials at a large scale. For example, penicillin is made through an organic reaction that converts 6-aminopenicillanic acid into penicillin G, an important antibiotic. These examples highlight the relevance of organic reactions in our daily lives and their contribution to improving our quality of life.

Pengembangan

Durasi: (75 - 85 minutes)

The development phase will allow students to practically and interactively engage with the concepts of organic reactions. These activities aim to solidify the recognition of reactants and products, the understanding of synthesis routes, and the significance of catalysts. Additionally, students will enhance their communication and teamwork abilities, which are crucial in both academic and professional environments.

Saran Kegiatan

Disarankan hanya satu dari kegiatan yang disarankan yang dilaksanakan

Kegiatan 1 - The Hunt for Products and Reactants

> Durasi: (60 - 70 minutes)

- Tujuan: Quickly identify reactants and products in organic reactions, encouraging quick thinking and teamwork.

- Deskripsi: In this activity, students will form groups of up to 5 and will receive cards detailing various organic reactions. Each card will list the reactants of a reaction and challenge students to identify the resulting product. The cards will be placed at different stations around the classroom.

- Instruksi:

• Divide into groups of up to 5 students.

• Each group starts at a different station.

• Read the card's description and identify the product of the reaction.

• Record your findings in your group's notebook.

• After 10 minutes, groups will rotate to the next station.

• At the end, each group presents their answers and discusses their findings with the class.

Kegiatan 2 - Real-Time Synthesis Route

> Durasi: (60 - 70 minutes)

- Tujuan: Enhance practical synthesis skills and comprehension of reaction pathways while reinforcing the significance of experimental conditions.

- Deskripsi: Students will be split into groups and will receive a 'reactant kit' along with instructions to perform a simple synthesis reaction, such as ester formation. They will follow the instructions to discover the correct synthesis route and generate the expected product.

- Instruksi:

• Divide the class into groups of up to 5 students.

• Distribute the reactant kits and instructions to each group.

• Follow the instructions to carry out the synthesis reaction.

• Identify the product created and detail the process taken.

• Discuss as a group whether the reaction was successful and the reasons behind it.

• Present findings and discuss alternative synthesis routes.

Kegiatan 3 - The Great Catalyst Debate

> Durasi: (60 - 70 minutes)

- Tujuan: Deepen understanding of the role of catalysts while developing argumentation and public speaking skills.

- Deskripsi: In this exercise, each group of students will be assigned to advocate for a specific catalyst used in a typical organic reaction. They'll receive background information on the catalyst and must prepare arguments to convince the class that theirs is the most effective.

- Instruksi:

• Organize into groups of up to 5 students, each assigned a different catalyst.

• Allow each group time to research the catalyst and its usage.

• Each group must prepare a defense detailing why their catalyst is the best for the reaction assigned.

• Conduct a class debate, where each group presents their arguments.

• Conclude with a vote to determine which group made the most convincing case.
