Role play: Divide the class into pairs. One student will play the role of an environmental activist and the other will play the role of a government official. The activist must convince the official to implement stricter regulations on pollution caused by factories. They should use the first conditional to express the potential consequences of not taking action (e.g. If we don’t reduce pollution, we will cause destruction to our environment).

Vocabulary matching: Provide a list of words related to the environment and their definitions. Students must match the words with their correct definitions (e.g. Resources - materials or substances that can be used to fulfill a need).

Sentence completion: Give students incomplete sentences using the first conditional structure and ask them to complete them using the vocabulary provided. For example, “If we continue to dump waste into the ocean, we will ____ the marine life.”

Group discussion: Divide the class into small groups and assign each group a different environmental issue (e.g. air pollution, deforestation, water scarcity). Each group must discuss the potential consequences of not addressing the issue using the first conditional. They should also brainstorm possible solutions.

Writing task: Ask students to write a short paragraph describing a hypothetical scenario in which a nuclear weapon is used. They should use the first conditional to explain the potential consequences of such an event (e.g. If a nuclear weapon is used, it will cause widespread destruction and loss of life).

Vocabulary game: Play a game of charades or Pictionary using the vocabulary words. One student must act out or draw a word while the others guess what it is. This will help reinforce the meaning and usage of the vocabulary.

Reading comprehension: Provide students with a short text about the ozone layer and its importance. After reading, ask them to answer comprehension questions using the first conditional (e.g. If the ozone layer continues to deplete, what will be the consequences for human health?).

Listening activity: Play a recording or video clip about the impact of pollution on wildlife. Students must listen carefully and identify the potential consequences mentioned using the first conditional.

Grammar exercise: Provide a list of sentences and ask students to rewrite them using the first conditional structure. For example, “The population will suffer from a shortage of resources if we don’t take action” can be rewritten as “If we don’t take action, the population will suffer from a shortage of resources.”

Debate: Divide the class into two teams and assign each team a different stance on a controversial environmental issue (e.g. nuclear energy, plastic waste). Students must use the first conditional to support their arguments and predict the potential consequences of their chosen stance.
