Simulating and Studying Greenhouse Effect in your classroom with Arduino UNO

The lesson employs a hands-on approach, involving a Greenhouse Effect Simulation using an Arduino UNO. This approach, following the principals of J. Bruno’s learning by discovery and trying to avoid the criticism to the original greenhouse effect experiments raised by a recent paper (M. Bertò et al, 2014) aims to make the subject more interesting for students, fostering practical skills in science and technology. Students experiment with modifying variables in a simulation setup, which includes a glass basin with limestone gravel, an infrared lamp, and a sprayer. The simulation introduces the concept of acid rain and its interaction with limestone, resulting in the release of CO2. Three scenarios are explored: one without CO2, one with water vapor but no CO2, and one with "acid rain on limestone," generating CO2. The sources of atmospheric CO2, including natural and anthropogenic processes, are discussed within this context. To monitor temperature changes in the simulation, students use Arduino, a temperature sensor and an infrared sensor allowing them to analyze and understand the impact of different scenarios on temperature patterns. The lesson emphasizes the importance of monitoring temperature changes in correlation with climate patterns, providing students with a tangible connection to real-world challenges. Note that basic Arduino concepts are introduced to familiarize students with microcontrollers, sensors, and programming.   Subject: Geology - Geography, Chemistry, Informatics Grade: 12-14 years old Duration:  two class periods General Objectives: This lesson includes a brief overview of greenhouse effect and its causes and impacts on temperature patterns and climate change.
