The Year 6 ‘How the World Works’ unit of inquiry began last week with a messy crime scene investigation. The students were required to use their observation skills to search for evidence that would prove how long it had been since the criminal left the scene. Students used their sight, smell and sound senses to search for clues of substances that show change and gathered their evidence. In the coming weeks, the students will use their scientific thinking to inquire into ways that substances change, how scientists document their thinking and practical applications of change in substances. By the end of this unit the Year 6 students should have an enduring understanding that ‘Matter exists in different forms which can be changed and used for a variety of purposes.’
