Knowledge of waves

What do you know about waves now, then what you knew before?

  • Now i know a lot more, because now i know more types of waves and how they work. Also how they move and how they effect in good ways and bad ways. Like irradiated waves, they can be bad because they can cause a lot of bad sicknesses. 
  • Also there are X rays which i knew before because i broke my arm and then i saw my arm. Also i could see my brain.  
  • The thing i most liked was the ultraviolet, because it was very interesting and it ad a lot of interesting facts to explain to me what it does and how it can help and not help. 
  • I wouldnt change anything because i thought me and Mary did a very good job with the info and how we set it up.

Food Radiation

Notes

  • Food travels a long way to get to your plate. 
  • Potatoes come from Maine and strawberries from Florida or Mexico. 
  • Sometimes food makes people sick.
  • Millions of Americans get sick every year from contaminated or spoiled food.
  • A way to preventing you from getting sick is to treat your food by irradiation.
  • Gamma rays are sent through fresh or frozen foods. 
  • More then 40 countries dont allow food irradiation. 
  • Radiation kills living cells. 
  • It can destroy nutrients.
  • Irradiation doesnt make food radioactive.
  • Irradiated food must be labeled.
Questions 

  1. In your own words explain the problem of food irradiation. 
The problem to me is that food irradiation is being taken lightly and not seriously. So more and more and eating irradiated food even thought they dont know its bad and what it can do. 

    3. You see two containers of a food at the supermarket. One is irradiated; one is not. The price s the same. Which would you buy?

I would buy the one that is not because it is healthier and i dont really trust irradiated food. I also dont really know what it does, so i would rather just stick with normal foods.
