Science questions..

In science today, a lot of questions arose that I didn't have answers for. Feel free to do some research to answer any of the following questions and post them as a comment. Extra credit goes to the students that have the correct answers!

• Explain, in detail, the pasteurization process.
• When was soap made/created/used?
• When were outhouses used?
• When did people start to have plumbing in their house to allow for running water and toilets to be used?
• Any other questions that you had? Just comment and tell me the question you had and what the answer is!

Element Symbols

Some students in class asked why some elements had symbols (abbreviations) that were not using any of the letters that were in the name. For example, Potassium has a symbol of K, Sodium has a symbol of Na. WHY???? If you can find out, please EMAIL me so that multiple people can respond for extra credit. I will post on here what students get the extra credit and will put the answer on here by Monday.

LBS???

Leah asked a very thoughtful question today asking "Why is the abbreviation for pounds, lbs?". In order to allow multiple people extra credit, feel free to email me the answer. If you get it correct, I will let you know in class. Good luck!
