Any topic associated with the environment that comes under the EVS like animals, water, plants, and their parts, etc. can be discussed in the EVS class too. Animals are an important part of the environment, so anything related to animals can be undoubtedly discussed in EVS class and one of the topics about animals is 'protection of animals'.The same applies to water also. As all the plants and animals in the environment rely on water for survival 'water crisis' can also be discussed in the EVS class.Different gases in the atmosphere play an important role in the survival of plants and animals and the process of plants generating from seeds also become a topic capable to be discussed in the EVS class. Additional InformationPETROL PRICES come under the topic of a country's economy as it is associated with money, so this topic becomes an economic topic rather than an EVS one. So this should be discussed in economic class more than in EVS one.Hence, we can conclude that protection of animals, water crisis, and concentration of carbon dioxide in the germination of seeds.
