As a Middle orHigh SchoolEarth Sciences, Environmental Sciences, or Geography teacher, you can use this lesson plan to teach the Earth’s climate system and help your students understand different aspects of Earth’s climate using simulations. This lesson plan is based on the web-based tool ‘Earth-Like’ developed at the Earth-Life Science Institute, Japan.
This lesson plan introduces Earth’s climate system, an overview of the Earth-Like simulator, and provides a guided exercise that uses the simulator to help your students understand what are the main factors that determine the climate of planet Earth.
There are several factors that impact the surface temperature andthe climate of the planet. These include the role of the sun and solar flux incident on the planet, the roles of the atmosphere and its greenhouse effect, the hydrosphere, the lithosphere, the biosphere, the cryosphere, the anthroposphere, and their interactions on a variety of spatial and temporal scales. This lesson plan demonstrates the use of the Earth-Like simulation to explain select aspects of the Earth’s climate system.
Thus, the use of this lesson plan allows you to teach Climate Science and Climate Change in your Earth Sciences, Environmental Sciences, and Geography classrooms. This lesson plan is particularly effective to use in a flipped classroom and as a blended learning educational resource.
Use this lesson plan to help your students find answers to:
What would Earth’s average surface temperature be if the sun was a Red Dwarf (0.002 L) like Proxima Centauri? If it was a Yellow-White Dwarf (5 L)?
What role does the incoming solar flux play in determining the average surface temperature of planet Earth?
What do you expect the average surface temperature of the Earth to be if the rate of volcanism increases?
What would Earth’s climate be like if it was much closer to the Sun?

Introduction to the Earth’s Climate System
Introduce the Earth’s climate system to your students through the video lecture ‘Earth’s Climate System’ developed by the University of British Columbia as part of the course titled ‘Climate Literacy: Navigating Climate Change Conversations’.
Emphasize the following topics from the video lecture: What determines the climate of planet Earth, specifically the significant role of the sun and the solar energy flux received on the planet, and the roles of the atmosphere, biosphere, geosphere, hydrosphere, and cryosphere.
Introduce your students to the Earth-Like simulator developed at the Earth-Life Science Institute, Japan. This simulator was developed as a project from the ELSI Origins Network Planetary Diversity Workshop.
The Earth-Like is a simulator allows you to render new planets and examine the average surface temperature and the climate of the planet by varying the most significant contributors to the Earth’s climate system. The simulator has two options: A classic toolkit and an advanced toolkit. The simulator includes the following:
Classic Toolkit
1. Fraction of the planet's surface covered by land
2. The rate of volcanism
3. Position within Habitable zone
Advanced Toolkit
1. Fraction of the planet's surface covered by land
2. The rate of volcanism
3. The type of sun
4. The distance from the sun
Your students can choose either toolkit to evaluate the roles of each of the factors listed above in determining the climate of the planet. The simulator can be used by changing the values of these factors and rendering a new planet. The results are given in terms of the average surface of the temperature of the new planet and are compared with that of our current-day Earth.
The Earth-Like website also includes a brief description of climate science and specifically the role of land fraction cover with an emphasis on the weathering reaction, rate of volcanic degassing, solar insolation levels, the planetary thermostat and the carbon cycle. A description of the model and the mathematics behind it is also provided.
Give your students an assignment and ask them to answer the following questions. At the end of each question, emphasize to your students how varying each factor changes the average surface temperature of the planet. This will allow them to better understand the role of these factors in determining planet Earth’s climate. The solutions to the assignment are provided as a separate downloadable document.
