This Week in Physics
On Monday we will finish discussing unit 3’s PODCAST 1: Net External Force, Weight, and Normal Force and will work on assignment 1. On the day after we finish assignment 1 we will take a quiz over goal set 1. Your notes from PODCAST 2: Friction are also due on that date. We will spend the rest of the week discussing friction, doing assignment 2 and exploring friction in the lab. (Note: Third period will not get to assignment 1 on Monday.)

A reminder: Your lab report over the Human Cannonball Projectiles Lab is due on Thursday at the start of class. One hard copy must be handed in at the start of your class period, and by 3:00 on that day one (and only one) copy must be uploaded to TurnItIn.com. You also must share your Google Doc with me as an editor at [email protected]. (Note: This is not my primary email address.) Additional documents you will need are the Lab Report Writing Guide and the Lab Report Rubric. You will need to create a scatterplot in Excel and copy-paste it (and your data tables) into your Google document. Here’s a handy video tutorial that shows how to format your data tables and make a scatterplot.

Cool Science of the Week
Can science and technology help counter climate change? This article identifies seven megatrends that provide some hope, including dramatically falling costs for generating energy from solar and wind sources, including making batteries that store more energy (increasing the efficiency of electric cars), and including …brace yourselves… lab-grown meat!
