Physical Science


In grade three, students investigate the physical properties of different materials and learn that changes occur in those materials. They explore mixtures and investigate examples of light, sound, and heat/thermal energy in everyday life. Students manipulate objects by pushing and pulling to demonstrate changes in motion and position.

Students also learn that the study of science requires appropriate tools and safe practices when planning and implementing investigations, and that it involves asking and answering questions, collecting data by observing and measuring, and using models to support scientific inquiry about the natural world.
