Viewing the Sun Safely

Introduction

The Sun is Earth's closest star.  It is so large that about one million Earth's could fit inside of it!  It is made up of mainly hydrogen and helium gases.  The Sun could be considered the boss of the solar system, with all of the planets revolving around it.  As you know, it takes the Earth three hundred sixty five days to revolve around the Sun once.  

Much of planet Earth relies on the Sun's heat energy.  Humans need the Sun to exist on Earth.  Without the warmth from the Sun, we could not survive.  The Sun's energy is needed for photosynthesis of plants, which we eat as food.  Today, the Sun's energy is also used to provide some homes with electricity and hot water.

Task

Many people on Earth are not aware of how powerful the Sun's energy is.  After only 3 seconds of looking at the Sun, your eyes can become permanently damaged.  There are no pain receptors in the retina of the eye so there is no pain to warn us of the damage being done.  


Your job is to create either:

  • a 1 page document, using Microsoft Word, that teaches other people how to protect their eyes from the Sun.  

    OR
     
  • a Powerpoint or Prezi presentation, that teaches other people how to protect their eyes from the Sun.
    **NOTE: If you are creating a Powerpoint or Prezi, please email it to me at: Lyndsay.Bender@lethsd.ab.ca**
     
  • You will have only this class to work on it.


Your page must include the following:

1) Name and Class
2) Why it is important to protect your eyes from the Sun
3) 3 ways to safely view the Sun
4) 3 ways to unsafely view the Sun

5) Pictures of 3 safe Sun viewing objects (for example: pinhole camera)
6) Descriptions of the 3 safe Sun viewing objects you have chosen 


Be creative!  This is an information sheet, but we want people to be excited to read it!

Evaluation

Your project will be marked on whether or not you have included the necessary elements.

Use this as a checklist to make sure you have completed the project.

  •  Have I put my name and class on the page? 
  •  Have I explained why it is important to protect your eyes from the Sun?
  •  Have I included 3 different ways to safely view the Sun? 
  •  Have I included 3 different ways to unsafely view the Sun?
  •  Did I put pictures of 3 safe Sun viewing objects?
  •  Did I describe my 3 safe Sun viewing objects? 


The project you have created will meet this "I Can" statement: I can explain the safe/unsafe ways to view the Sun.
