Grade 3


Science Grade Three 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 gravity, stars, forms of energy, motion, heat and light, properties and changes in matter, plant structures and functions, plant responses, plant and animal classification, and adaptations.
