In Grade 3, students explore how organisms form groups that help members survive, analyze how habitats support different organisms, and investigate how environmental changes affect plants and animals. They examine how variations in traits can provide advantages for survival and develop an understanding of the interdependence of living things within ecosystems.
By the end of Grade Three, the learner will be expected to:
Assessment strategies that provide information about learning:
Interdependent Relationships in Ecosystems in Grade 3 builds upon students' earlier experiences with plants, animals, and their environments. Students develop a deeper understanding of how organisms interact with each other and with their environment. They learn about the benefits of group living for many animal species, how fossils provide evidence of past organisms and environments, how environmental changes affect ecosystems, and how variations in traits can provide advantages for survival. Through investigations, research, and modeling activities, students develop an understanding of the interdependence of living things and the importance of biodiversity for healthy ecosystems.
