Science Grade Four is an intermediate course with concepts across many types of sciences including Earth Science, Life Science, and Physical Science. Through asking questions, making predictions, making and comparing observations, making inferences, working with others to conduct investigations, explaining the results of investigations, developing models, constructing arguments, and making claims, students will learn about magnets, motion of objects, energy, properties of matter, physical weathering and erosion, rocks and minerals, plant and animal life, heredity, resources and the environment, seasonal changes, and Earth’s movement.
