                         Health or Physical Science

Date: ________________                        Name: __________________

      For a ½ credit in Health or Physical Science do the following.

I.   Read:   Part 1 “How Radiation Was Discovered” and “Radiation
      and You”

     A. Define the following:

         1.   Alpha radiation                        2.  Beta radiation
         3.   Black light                                4.  Cosmic rays
         5.   Electromagnetic spectrum         6.  Fission
         7.   Fusion                                       8.  Gamma rays
         9.   Infrared                                   10.  Ion
        11.  Ionization radiation                 12.  Isotopes
        13.  Microwaves                              14.  Neutron
        15.  Nucleus                                    16.  Ozone
        17.  Radiation                                 18.  Radioactive
        19.  Radium                                    20.  Rem
        21.  Speed of  light                          22.  Ultraviolet
        23.  Uranium                                   24.  Wavelength
        25.  X-rays

     B. Research the following people on the internet 
       ( go to www.metacrawler.com)
         What are their contributions to Health and Science , and when 
         did  they live and die or are they still living?  (Half a written 
         page for each)

         1.   Becquerel, Henri                   2.   Newton. Issac
         3.   Roentgen, Wilhelm               4.   Curie, Marie
         5.   Maxwell, James                    6. Young, Thomas

    C. Research the following on the internet.  Do a one page 
         investigation.

        1. Ozone is an interesting chemical.  It is harmful when we
            breath to much of it.  It is necessary at high altitudes to
            keep out potentially harmful radiation coming to us from 
            the sun.  In other words, we don't want ozone and we do
            want ozone.  Investigate the details of this problem today. 
            Look into contributions trees make to ozone accumulation.

            a. (http://www.safeparks.org/urbantrees.html)

            b. (http://www.epa.gov/ozone/science/makemore.html)

              c.  (http://sedac.ciesin.org/ozone/)
 
 

       2. Investigate specific ways the sun's radiation can help and
           harm.  One unusual application of sunlight today is in 
           combating depression.  See if you can come up with others. 

          a.   Harmful
        (http://odp.od.nih.gov/consensus/news/release/074_release.htm)

          b.   Helpful

Enabling Activity
   Students will research the internet for web resources to collect data for their hand
written activities.  Students will also be given handouts to help them with there
investigations of terms and scientists.

Culminating Activity
Students will turn in all hand written papers for evaluation (must pass with 70% or better).  Students will be given a test (must pass with 70% or better).
