Tujuan Tambahan:

1. Encourage students' critical thinking through a comparative analysis of different animal groups.

Pengantar

Durasi: (15 - 20 minutes)

The introduction aims to captivate students and relate their existing knowledge to the topics we will delve into during class. By presenting problem situations, we encourage critical thinking and the application of concepts they have previously studied. The contextualization aspect illustrates how learning about vertebrates and invertebrates is relevant to real-world scenarios, thereby boosting student interest and involvement.

Situasi Berbasis Masalah

1. Imagine an explorer who has just landed on a vibrant new island teeming with diverse wildlife. He spots a swarm of tiny creatures that dart about swiftly, but none appear to possess a backbone. How might the explorer quickly discern if these creatures are vertebrates or invertebrates?

2. Picture a marine biologist examining beings from the seafloor. He notices a collection of animals sporting hard shells yet lacking any bones. How could the biologist figure out if these animals belong to the vertebrate or invertebrate category?

Kontekstualisasi

Understanding the distinctions between vertebrate and invertebrate animals goes beyond academics; it's vital for various disciplines like biology, ecology, and even conservation efforts. For instance, identifying invasive species, often invertebrates, helps mitigate harm to local ecosystems. Moreover, the curiosity peaks when considering that the majority of animals on the planet are invertebrates, including insects, mollusks, and worms, making this area of study all the more engaging.

Pengembangan

Durasi: (70 - 75 minutes)

The Development stage facilitates a hands-on and interactive application of knowledge regarding vertebrate and invertebrate animals. Group work not only solidifies their understanding but also hones their communication, cooperation, and critical thinking abilities. Each activity is designed to deepen the distinction between the two animal types, using fun, contextual methods to enrich learning.

- Tujuan: Reinforce knowledge regarding the classification of vertebrate and invertebrate animals, while promoting teamwork and scientific reasoning.

- Deskripsi: Students will be divided into groups of up to 5 and each group will receive a 'magic hat' filled with cards featuring different animal names. The challenge is to quickly classify these animals as either vertebrates or invertebrates and indicate whether they possess an internal or external skeleton. Each team must justify their classifications using the characteristics they studied earlier.

- Instruksi:

• Split the class into groups of maximum 5 students.

• Hand out a 'magic hat' to each group containing cards with animal names.

• Set a timer for 30 minutes for groups to classify and justify their choices.

• Each group will showcase their classifications and explanations to the rest of the class.

• Facilitate a discussion after the presentations to address questions and reinforce understanding.

Kegiatan 2 - Skeleton Olympics

> Durasi: (60 - 70 minutes)

- Tujuan: Cultivate practical skills in identifying and associating characteristics of skeletons, while also encouraging collaboration within teams.

- Deskripsi: In this task, students will 'dissect' models of animal skeletons (both vertebrates and invertebrates) crafted from materials like straws, sticks, and playdough. Each group will receive a skeleton along with a set of characteristic cards. They will need to determine which category the skeleton falls into (vertebrate or invertebrate) and match the corresponding characteristics.

- Instruksi:

• Set up the classroom with workstations, each featuring a skeleton model and a set of characteristic cards.

• Divide students into groups and have them rotate between stations every 10 minutes.

• Students should identify whether the skeleton belongs to a vertebrate or invertebrate and match the correct characteristics.

• At the conclusion, each group will present their findings and learnings to the class.

• Wrap up with a review of the associations made by each group.

Kegiatan 3 - Skeleton Builders

> Durasi: (60 - 70 minutes)

- Tujuan: Foster creativity and a practical understanding of the structural differences between vertebrate and invertebrate animals.

- Deskripsi: In groups, students will receive assorted materials like pasta, gelatin, and wires to create their own animal skeletons. They must identify whether their constructed animal is vertebrate or invertebrate based on its structure, and explain their reasoning for the chosen skeleton type.

- Instruksi:

• Form groups of up to 5 students.

• Distribute building materials among each group.

• Groups need to construct a skeleton and decide if it depicts a vertebrate or invertebrate.

• Each group will present their skeleton and rationale to the class, followed by a voting session for the best explanation.

• Discuss how the differences between created skeletons relate to the actual characteristics of animals.
