Light

Light is everywhere in our world. We need to see: it carries Information from the world in our eyes and minds. Colors and shapes to is second nature to see us, yet light is a perplexing phenomenon when we study it closely. Light is a wonderful topic to study for school, for Part because some facet of it can at all levels grade teaching.

Younger primary school students can create their own shadow against himself . Compare If you could it, questions like your shadow as you? Is it higher or shorter, or just the same height? These students will, in an Mirror to increase their right hand and answer to the question of which hand Reflection is triggered? At this stage they are only informal observations about light and color.

Here are some things to think about:

• Our brain and eyes to act together to do extraordinary things happen in perception. Movies are sequences of still images. Magazine Images are arrays of dots.
  
• Light acts like particles - little light bullet-stream from the Source. This explains the workings of the shadow.
  
• Light also acts like waves - curl in the room - instead of Bullet. This explains how to work Rainbows. In fact, light both. A "wave - particle duality" is one of the most confusing - and wonderful - principles of physics.

Scientists have lifetimes consistent physical development, biological, chemical and mathematical explanations for these principles issued. But we can on the road to deeper understanding without the begin equations to do as a scientist: make observations, Conduct experiments and test our assumptions against what we see.
