This one-page worksheet completely in Spanish is meant to help students master environment vocabulary. They are asked to define several words and phrases that have to do with the environment and ecological problems. Then, they are asked to answer questions about the environment (ie. What is the biggest ecological problem in our world and what are the possible solutions?). Finally, they are asked to pretend that they are the mayors of a city. They must explain the ecological problems that they have in their city and how they got rid, or will get rid, of them. Good for in class work or some in class work and a take home composition.
