2. Solve practical problems of heat exchanges and temperature changes, especially when mixing two masses of water with different temperatures.

Side Objectives

1. Relate the concept of sensible heat to everyday situations, such as mixing hot and cold water for a bath.

Introduction

Duration: 15 - 20 minutes

This stage aims to engage students right from the start with the topic of sensible heat, using technology and the internet as research tools. The goal is to spark initial curiosity and foster a discussion environment, where students can share their discoveries and use them as a basis to deepen their understanding of the topic during the lesson. Additionally, the key questions help ensure that students are ready to actively participate in the subsequent practical activities.

Warming Up

🌡️ Introduce the topic of Calorimetry: Sensible Heat to the students in a simple way. Explain that sensible heat is the amount of heat required to change the temperature of a substance without changing its physical state. For example, when we heat water in a pot, we are adding sensible heat. Then, ask the students to use their phones to find and share an interesting fact about sensible heat, encouraging them to find practical applications in everyday life, like in cooking or climate control.
