Term 3 Integrated studies unit: Light Fantastic

Posted in Science on 06/20/2009 08:34 am by Mrs Baldwin

What would our lives be without light? We need it to see everything we do in every moment of the day. We rely on light to read a book, cross the street, admire artwork, watch the sunset and look into faces. Light plays a role in some of our most sophisticated technology. It enables our CDs to play music or record movies. High speed optical cable is used in our communications. Through your investigations you will be able to explain how light enables us to see and how we can use light to meet our needs.
