 Hello, this is Dorsaf Gatri, one of the STEM teachers at ICT.

 As a teacher, one of my main focuses is to foster students’ interest in a particular topic. This would involve, amongst other things, tackling topics that have a direct influence on the students’ lives and/or future.

 When I learned that students will have the opportunity to choose for themselves if they wanted to join Biology class or another class, I realized that half of the task is done: All the students in my class would already be interested in what I have to teach. What is left to do is to use this golden opportunity to introduce young, bright minds to one of the biggest challenges that is facing us in the 21st century. 

 It is no secret that the news about the decline of the state of our environment is worrisome, to say the least. Environmental science is an interdisciplinary subject. This might be a reason to think of it as a complicated matter. It can also be a reason for hope; history shows us that big challenges can be overcome when humans collaborate. This biology class tried to enforce the following ideas:

Hope is part of the solution:

 There is a myriad of reasons to why we should be very concerned about the environment, however this does not mean that all hope to turn the tables is lost. Students were taught that human ingenuity can mitigate environmental issues. We discussed examples and possible innovative ideas to get humans needs met while preserving the only home that we know: the earth. Some of the solutions mentioned in class are: 
-Decentralized energy systems using microgrids
-Shared driverless cars to reduce GHG emission related to transportation
-Grazing animals’ systems as opposed to industrial livestock 
-Using seaweed to restore the overturning circulation in the oceans

Understanding the problem is the first step to the solution:

 Different activities and experiments were conducted to illustrate the concepts explained in class.

 One of these activities was a fishing game to explain the concept of the Tragedy of the Commons. In this activity students were part of an imaginary village and were competing against each other to catch fish. Each type of fish had a price tag. The winner of the game would be the richest person in the village.

This is how the game is played: Students have four 30 seconds turns with each turn corresponding to one fishing season. During each of these turns, students try to catch fish using a tape attached to two straws and they must make at least 500¥ to keep playing. At the end of each term, each pair of fish will produce two offspring.

 As expected, the students, hoping to be the richest and win, depleted all the fish in the ocean in the first round. This is when they realized that the only way to win this game is to come up with a sustainable strategy and make sure that there will be enough fish in the ocean for them to catch next season. I reset the game and the students were given another chance during which they worked together to maintain natural resources. Using an environmentally friendly approach to play, the students ended up with more financial prosperity.

 Another important experiment that was conducted is the soil salinization experiment. The students monitored the growth of mung beans using different salinity levels. The results of the experiments showed clearly the adverse impact of salinity on plants and, by extension, on our food sources.

 To sensitize the students to the problem of biodiversity loss and its impacts on ecosystems, they were introduced to taxonomy (the science of naming animals and plants) and ecology (the study of the interaction between the organisms and their environment). The taxonomy classes were followed by a microscopic observation of different animals and plants. The ecology classes were followed by a classroom food web activity. In this activity, the students, each representing an animal from a particular trophic level, had to draw that animal, hang it on the board and work together to create a food web.

The scientific method is the reliable way towards the solution:

 The students used the scientific method to brainstorm an experimental design to test the air quality of different locations of their choice. They presented and discussed their qualitative and quantitative data. This helped the students to not only learn about the different types of air pollutants and their sources, but also to familiarize themselves with the scientific method and the scientific jargon. 

 The students enjoyed this class and so did I. Next semester we will laser-focus on the most pressing of environmental issues: Climate change.
