Our next unit of work in Year 6/7 Science will be Light and Sound. We will learn about luminous, incandescent and fluorescent objects and bioluminescent organisms (such as glow worms, some deep-sea fish and phosphoresence in the ocean.) We will also find out about the structure and function of your eyes and ears. We will find out the answers to the following questions:
- What makes a rainbow?
- What are polarised sunglasses?
- Why can’t you see through tinted windows?
- How do some animals see in the dark?
- Why can’t anyone hear you scream in space?
- What is a wave?
- Why can’t humans hear sounds that some animals can?
“How Stuff Works” is a great site for finding out how light and sound work. Some good resources from Scholastic StudyJams here. Recent article from New Scientist about how brain damage can have interesting effects on eyesight. The Bioluminescence Web site has some great information about the living organisms that emit light. Here are some links to some good Sound and Light Experiments you can do at home at Fizzics Education and ACS Chemistry for Life.
