Your first lab assignment in Chemistry Survey is to take care of lab-related business-- the lab safety contract and finding, buying or ordering the materials you'll need starting in Week 1. This information will also be listed in your Chemistry Survey Resources packet (the last packet in this course) so you can find it again easily when you need it. LAB SAFETY An important first step in laboratory safety is for you and your parents to sign a contract that will help guide your steps when doing at-home science experiments. We won't require you to handle dangerous materials, but any activities involving heat, electricity, water, etc. require your conscientious participation. Please go to this web site to print out the Flinn Scientific Student Safety Contract: http://www.flinnsci.com/Documents/miscPDFs/Safety_Contract.pdf. (Be patient; the document can take a few minutes to load!) Print two copies--one to sign and mail to MNOHS, and one for your work area. Be sure to read the contract carefully before signing, and before taking the Week 1 Lab Safety Quiz. You must sign the lab safety sheet. If you are under 18, your parents must sign it as well. Send it to:
Minnesota Online High School
Att: Ms. Raffa
University Technology Center, Suite 227
1313 Fifth Street SE
Minneapolis, MN 55414 If you have any questions about the contract, please contact Elissa Raffa at elissa.raffa@mnohs.org. REQUIRED MATERIALS Many weeks in Chemistry Survey, you will have one an at-home lab activity. These can generally be completed using common household supplies and utensils that can be bought at your local supermarket, discount store, pharmacy, hardware store, etc. Below you will find a week-by-week list of these materials. When doing at-home lab activities, it's a good idea to wear inexpensive safety goggles. You can find these at a hobby or hardware store, or order them from Ward's Natural Science for approximately $4.00 plus $5.00 for shipping. You can order from Ward's online using a credit card or you can call their customer service number (listed on the web site) to place an order by phone and pay with a credit card or check. Do not send a check without calling first! If you have any questions about the Lab Safety Contract or lab equipment and supplies, please contact elissa.raffa@mnohs.org. Thank you!
