Prinsip: Rencana Pelajaran Aktif ini mengasumsikan: durasi kelas 100 menit, studi sebelumnya oleh siswa baik dengan Buku maupun awal pengembangan Proyek dan bahwa hanya satu kegiatan (di antara tiga yang disarankan) akan dipilih untuk dilaksanakan selama kelas, karena setiap kegiatan dirancang untuk mengambil sebagian besar waktu yang tersedia.
Tujuan
Durasi: (5 - 10 minutes)
The Objectives stage is vital for laying down a clear and strong foundation for what students are set to learn and explore during the lesson. By outlining specific objectives, the teacher prepares not only themselves but also the students, ensuring everyone's on the same page regarding the focus of activities and discussions. This stage also serves to inspire students by demonstrating how the concepts of heat and temperature are relevant in real life, thus enhancing their engagement and the significance of what they study.
Tujuan Utama:
1. Explain and differentiate between heat and temperature, focusing on their practical and theoretical applications.
2. Discuss how our thermal sensation can vary from the actual temperature, especially in familiar everyday situations.
Tujuan Tambahan:
- Encourage students to actively participate through group discussions and hands-on experiments.
- Develop students' observation and critical thinking skills by examining natural phenomena linked to heat and temperature.
Pengantar
Durasi: (15 - 20 minutes)
The purpose of the Introduction is to actively engage students and revisit prior concepts, utilizing problem situations that spark critical thinking and application of knowledge. Additionally, this contextualization links the topic to real-life scenarios that students encounter, making the learning of heat and temperature more relatable and motivating. This initial phase aims to build the foundation for a deeper and more practical understanding of the concepts, fostering curiosity and interest among students.
Situasi Berbasis Masalah
1. Imagine you are at the beach on a sweltering day, but the strong breeze makes it feel cooler than what the thermometer indicates. Why does this happen?
2. In a local café, you order both a coffee and a cappuccino, served at 70°C. Why does the cappuccino feel hotter even though both are the same temperature?
Kontekstualisasi
Heat and temperature are concepts we encounter in our daily lives, but grasping their differences can be a bit tricky. For instance, during summer, a can of cold drink left in the sun heats up on the outside, while the inside remains chilled — the thermal sensation when you touch the can can be quite different from its actual temperature. This gap between perceived and measured temperature makes exploring these concepts interesting and relevant to our understanding of our environment.
Pengembangan
Durasi: (75 - 80 minutes)
The Development stage allows students to leverage and deepen their existing knowledge of heat and temperature through practical and playful experiences. Working in teams, students have the chance to experiment and observe thermal phenomena in real-life situations, enriching their understanding of these concepts while encouraging collective effort and critical thinking. Each activity is crafted to explore a unique aspect of the topic, from heat transfer to thermal perception, ensuring a comprehensive and engaging approach to the subject.
Saran Kegiatan
Disarankan hanya satu dari kegiatan yang disarankan yang dilaksanakan
Kegiatan 1 - Mystery of the Ice Cream That Doesn't Melt
> Durasi: (60 - 70 minutes)
- Tujuan: Understand the concept of heat exchange and how various materials can influence it.
- Deskripsi: In this activity, students will investigate why an ice cream left out in the sun for some time remains solid, even as the ambient temperature rises. They'll apply the concepts of heat and temperature to explain this phenomenon.
- Instruksi:
-
Divide the class into groups of up to 5 students.
-
Give each group a cone ice cream and a thermometer.
-
Ask the students to place the ice cream in a sunny spot for 30 minutes.
-
During this time, groups should record the ambient temperature and the ice cream's temperature every 5 minutes.
-
After 30 minutes, they should jot down their observations and reason why the ice cream didn't fully melt.
Kegiatan 2 - Perfect Cappuccino Challenge
> Durasi: (60 - 70 minutes)
- Tujuan: Understand how different material compositions can affect temperature perception.
- Deskripsi: Students will explore why two cappuccinos can have the same temperature but feel different in terms of heat. They will utilize thermometers and concepts of thermal conductivity to uncover the mystery.
- Instruksi:
-
Organize students into groups of up to 5 members.
-
Provide each group with two cups of cappuccino at 70°C, one made with varying ratios of milk and coffee.
-
Students should measure the temperature of both cappuccinos every 5 minutes and keep track of their findings.
-
After an hour, have each group present their observations and explain why one cappuccino felt hotter than the other.
-
Engage the class in a discussion about the conclusions drawn by the groups.
Kegiatan 3 - Thermal Treasure Hunt
> Durasi: (60 - 70 minutes)
- Tujuan: Identify the thermal properties of various materials and comprehend how they affect thermal sensation.
- Deskripsi: In this engaging activity, students will partake in a treasure hunt to identify various materials at different stations that either retain or release heat in diverse ways. They'll utilize thermometers and tactile assessments to gather data.
- Instruksi:
-
Set up stations around the school with different materials (like metal, wood, plastic, etc.).
-
Split the class into groups and give each group a thermometer and a list of materials available at the stations.
-
Each group will rotate through the stations, measuring the temperature of each material and noting if it feels 'cold', 'hot', or 'neutral'.
-
Groups must share their observations and form theories on why different materials exhibit different heat retention or release patterns.
-
At the end, each group will present their findings and theories to the class.
Umpan Balik
Durasi: (15 - 20 minutes)
This stage of the lesson plan is vital for cementing students' learning, allowing them to articulate what they've observed and learned during the practical activities. Group discussions help develop communication and reasoning skills while broadening their understanding of concepts through peer insights. This exchange of ideas reinforces the understanding of heat and temperature and their application across various contexts.
Diskusi Kelompok
At the conclusion of the activities, gather all students for a group discussion. Initiate the conversation by revisiting the lesson's objectives and inviting each group to share their discoveries and conclusions. Encourage students to discuss not only their results but also the thought processes that led them there. Use guiding questions to facilitate the discussion, ensuring that all dimensions of heat and temperature concepts have been thoroughly explored.
Pertanyaan Kunci

Kesimpulan
Durasi: (5 - 10 minutes)
The Conclusion seeks to solidify the knowledge acquired throughout the lesson, reinforcing connections between the theory and the practical activities undertaken. It also emphasizes the significance of understanding heat and temperature in everyday contexts, helping students recognize the practical implications of their learning in real-life scenarios. This stage serves to remind students of the importance of what they've learned and encourages a final reflection on the integration of theory and practice.
Ringkasan
To wrap up, let’s summarize what we learned today. Students explored the distinctions between heat and temperature, conducted experiments to grasp how heat transfers between materials and how this affects our thermal sensations. They discussed practical examples of how the temperature shown on a thermometer can differ from what we feel, like on a chilly, windy day.
Koneksi Teori
Today's lesson effectively connected theory and practice. Students were able to see and measure the concepts discussed, like heat conduction in various materials and how material composition impacts temperature perception. This hands-on approach reinforced their theoretical understanding, allowing them to apply their knowledge in a tangible way.
Penutupan
Understanding heat and temperature is essential not just for science but also for our daily lives. These concepts are critical in numerous situations, from preparing food to operating technology that controls our ambient conditions. Additionally, being able to differentiate between the temperature reported and our perceived thermal sensation empowers us to make better-informed decisions in various weather conditions.
