Radiation Effects on People

DAY 1
Get into a group of 3 or 4 and brainstorm on topics related to Radiation and its effect on people.
There are positive effects of radiation, such as for the following:  Your topics are not limited to the following topics but these are some ideas:

Pure research in radiation:  discovering elements
Discovering DNA using x-ray diffraction
Nuclear Power plants save energy
Nuclear medicine
-   using isotopes for cancer treatment
-   isotopes for imaging and diagnosis (breast cancer, x-rays, angiograms etc)
-   using subatomic particles to treat eye cancer at TRIUMF

There are negative effects:
The atomic bomb story. making the bomb
aftereffects of the bomb - victim impact Hiroshima, Nagasaki
Nuclear accidents - Chermobyl and other nuclear melt-downs
Japanese Tsunami and the radiation leak from nuclear power plants
Contamination of the ecosystem

ON A PIECE OF PAPER:
WRITE DOWN YOUR IDEAS ON THE POSITIVE AND NEGATIVE EFFECTS. Read the books provided by our librarian and come up with four proposals for a group presentation:
2 proposals deal with negative effects
2 proposals deal with positive effects

Have a good Winter Break

After winter break, we will start a new unit on Radiation, Nuclear Fusion, Alpha, Beta and Gamma Decay.  Our case study will be the Manhattan Project:  the science of the nuclear bomb and its devastating after effects on a population in Japan

Dec 18: Make a big summary sheet for your test next day!

Use a big 11 by 17 piece of paper and make a big summary sheet explaining how Bohr diagrams work and also Lewis diagrams.  Explain how to calculate atomic mass!  Use all the vocab words in your two worksheets handed out.  Make it creative, make it beautiful and colourful.  Explain how to draw the Lewis structure of ATOMS vs IONS.  When you are done, put your name on your summary sheet.  You will be given a mark out of 5 for your efforts today.

And try out these problems below:

2.  20 marks on acid base neutralization equations. 
3.  20 marks on balancing equations
4.  Challenging questions:  10 marks. 
I will give you a word equation.  You convert that to formula equation, and then balance it.

20 Multiple choice questions on Acids, Bases and indicators and our labs. See our worksheets on acid and base.

ex. What colour does phenylpthalein turn for base?  pink
What colour does litmus paper turn for acid?  red
What colour does universal indicator turn for base?  blue
