Innovators 7/8 S.I.R. Scientific Investigative Reporter

The world is full of scientific mystery and wonder.  There are also issues that concern scientists and the general public based on the effects on both man and his environment.  It is important that the general public is informed and made aware of these issues.  Your role as a S.I.R. is to continually inform the public of the scientific topic that you have selected.  You will report out every month using various informational methods (written, audio, and /or video).  You will be able to use numerous resources but you will have to stay current by only using relevant news from the past or current month only!  For Innovators 8, your reports will be web based and updated with links and posts to the blog.  Please do your job diligently and have fun reporting out!

Topics For Innovators 7 Include:

  • Pandemic     Global Climate Change
  • GMO's          Food-borne Illnesses
  • Environmental Chain Reactions        Stem Cells 
  • Genetic Engineering

Topics for Innovators 8 Include:

  •  Pandemics       Global Climate Change
  • GMO's              Food-borne Illnesses
  • Environmental Chain Reactions     Stem Cells 
  • Wildfires           Hurricanes
  •  Gravity & G-Forces     Steroids
  •  Structural Engineering Failures     Robots
  • Fuel Cells          Artificial Satellites
  • UV Rays            Genetic Engineering

Innovators 6/7/8 May Nature Connections...

May is though to be named after Maia Maiestas, the Roman goddess of fertility.  Flowers and blooms are very prevalent now as spring swings into full steam.  The birds and insects are busy pollinating and producing offspring while the trees are beginning to fill out as their canopies begin to create shaded areas once again.  The days are getting progressively longer as well as warmer a true sign that spring has taken hold.  For a naturalist, this is one of the most exciting times as so many changes are beginning to occur which provides great opportunities for observation and learning to occur.

May Nature Connection Assignments:

  • My Nature Notes pg 153 (2 a week for a total of 8) 
  • Go on a Nature Quest! pg 154 
  • The Picture of the Month pg 155    
  • Learning Your Local Birds pg 160-161
  • Spring Fever (and Hay Fever) pg 162-163 (read for understanding)
  • Quite Bugging Me! pg164-165

Innovators/7 The genetics of graying hair... do you aready have the gene for it?

The graying of the hair is often seen in two different lights, either you are getting old and that is why your hair is graying, or you can been seen as wise and sophisticated which is usually related to age.  Scientists have now found the gene responsible for the graying of one's hair and there is a possibility that one day the gene could be turned off. Watch the video to determine who is most susceptible to this gene.  Also weigh in on your thoughts about the manipulation of the gene for better or worse.

Innovators/6 Extinction again rears its ugly head...

Continuing on the extinction topic checkout this 60 second science clip about the possible fate of the giant flightless birds from the land down under (Australia).  What clues have lead scientists and paleontologist to believe that we humans may be responsible for their extinction many years ago?

Innovators/6 Were Dinosaurs Doomed Before the Asteroid?

Were Dinosaurs Doomed Before the Asteroid? - D-brief: A new analysis suggests the branches of the dinosaur tree of life were shriveling millions of years before the asteroid finished the job.  Just as we finish our study of geologic history, this article was published highlighting the end of the era of dinosaurs.  As you recall the Mesozoic Era was the age of the dinosaurs and that this ended due to a meteorite impact in the Yucatan Peninsula.  Yet this new information may just shed new light on the final days of the dinosaurs.  Discuss you thoughts about this new information and how this may possibly change our understanding of the end times of the Cretaceous.

STEM/7 Fruit Flies and Heredity

Our study of genetics and heredity has lead us to discover the importance of how genes and traits are passed on from one generation to the next.  Eukaroytic organisms use DNA as the blueprint to pass on these genes which are expressed as traits that we can identify by looking at the physical characteristics of that particular organism.  The use of the fruit fly has enabled scientists to study the passing of genes from one generation to the next through selective breeding.  the simplicity of this procedure has allowed us to do the same type of genetic experiments in the class with our own population of fruit flies.  This experience will allow us to see first hand the importance of genetic inheritance and the affects of mutation on the genome.  An article entitled "The Fly People Make History With The Fruitful Fruit Fly", addresses the use of the fruit fly and the importance of it in the scientific realm of genetics.  Based on the reading, comment on the following questions;

  • What claims does the author make for using the fruit fly for genetic studies?
  • Why do scientists use these "model organisms" to help understand human genetics?
  • Describe the fruit fly's attractive characteristics that makes it suitable for genetic study?
  • What is the "Homebox"?  What is its importance in the realm of genetics?
  • How does your study of the transferring of genes through selective breeding help you better understand who you are as a human and as part of your family?

Innovators 8- Development of the Atomic Theory

The atomic theory of matter is an excellent example of the process of science. Our understanding of the world around us is reshaped and refined with each scientific experiment. The first recorded idea of the atom comes from the ancient Greeks in the 400’s B.C. Over time, scientific experimentation has added to our knowledge of the atom, redefining what it is and what its structure is like.
In class you have been assigned a scientist who you will research and answer questions on the blog.  Some scientist have more than one student researching them but you are both required to submit your own research and post.  The post must be written in complete sentences and some questions will require more than one sentence to receive all the points.  You are all expected to read each other’s posts and take notes (your individual notes on the other theorist will not be graded).  On an exam I can ask about any of the scientists or theories.
Possible scientists are:
Democritus                                                      Antoine Lavoisier
John Dalton                                                     J. J. Thomson
Ernest Rutherford                                           Robert Millikan
Marie Curie                                                     James Chadwick
Albert Einstein                                                Niels Bohr                              
Erwin Schrodinger                                          Werner Heisenberg

Questions to answer in your research
1) When did they live? Where did they live?
2) What new information did they contribute to the understanding of the atom?
3) How did they find this new information? (What experiments did they do?)
4) Interesting facts – other accomplishments, personal information, famous historical events at the time, etc.

Research Tips
Many of these scientists have developed other theories and performed other experiments as well.  When searching online for information it is a good idea to search, “Niels Bohr Atomic Theory” to help narrow your search.  When finding other facts about your scientist searching just the name is a good way to search as well.
