How I know that light travels in a straight line? - Worksheet - Year 6

The Year 6 worksheet presents an experiment designed to demonstrate the concept that light travels in a straight line. The activity begins by directing students to watch a specific video which provides visual evidence and explanations pertaining to the behaviour of light. Following this, the worksheet prompts students to articulate what they have learned by writing down their understanding of how light's straight-line travel is evidenced and how this principle enables us to see the world around us.

Through this exercise, students are encouraged to contemplate and explain the fundamental role of our eyes in the process of seeing. They are asked to consider the evidence that supports the idea that light travels in straight lines, which is a core concept in the study of optics. The worksheet's aim is to foster a deeper comprehension of this scientific principle by engaging students in both observation and critical thinking, thereby reinforcing their learning through active participation and reflection.
