This Week in Physics
We will start off the week by examining graphs of position v time and velocity v time in ever increasing depth by completing assignment 1 together in class. We will also spend two days learning how to write lab reports. The following documents will guide us:
Your lab report is due on Friday, September 16 at the start of your class period. You will need to turn in one hard copy of your report in class, and you will need to have one person from your writing team upload one copy of your report to TurnItIn.com. The class ID is 13544558, and the password is Einstein. You can upload your report directly from Google Drive to TurnItIn.com using these instructions. The upload to TurnItIn.com is due by 3:00 on Friday.
Toward the end of the week, depending on the pace of your individual class, we may take a quiz over learning goal sets 1 & 2. Then, if assigned, please take notes on Podcast 5 – Introduction to Acceleration.
Cool Science of the Week
This past week the FDA (Food and Drug Administration) banned nineteen ingredients commonly used in antibacterial soaps, citing potential health risks from long-term use. They acknowledged that simply washing with regular soap and water is just as effective as using soaps with antibacterial ingredients. A side benefit of this decision may be to prevent bacteria from evolving to be resistant to antibacterial chemicals, which are still used appropriately in such settings as hospitals. We do know that bacteria can become resistant to antibiotics, and researchers this week shared evidence of this occurring within the confines of a petri dish. Bacteria that can resist antibiotics and/or antibacterial chemicals can become a threat to the health of humans and other living organisms.
