What I learned this week.
    In chemistry class this week we learned about lab safety what should be done and what should not, and if something ever happens what we should do about it. We also learned about the equipment, and utensils and what they are used for. We learned about the scientific method, and how most scientist don't follow it in order. Lastly we learned about hazardous materials, and how they are identified ether by color or scale. They are explained from 4-0 four being the most dangerous one.
  1.  Red would be flammability (likely-hood to catch on fire or how easily it does.
  2.  Blue would be health (or how it will affect your health.
  3.  Yellow would be stability. (or how easily it can cause a reaction likely to be an explosion) 
  4. White would be special. (special categories made for chemical that cause reactions but are not based on how bad, but on what they do)
