Happy St. Patrick’s Day and welcome to OGT testing week! This week means that we have SIGNIFICANTLY (up to 48%) less time together due to late start for juniors and seniors and a shortened daily bell schedule. Be ready to work in a very concentrated way in class.
This Week in AP Physics
Electrostatics homework 4 is due on Monday. My fingers are crossed that we’ll also be able to start electric circuits notes on that day. The electrostatics test is on Wednesday, your electric fields lab report is due on Friday (hardcopy at the start of class, upload to TurnItIn.com by 3:00), and we’ll really get into electric circuits on Friday. ALSO we are losing a day next Tuesday, March 24, because we have to do the end-of-course testing required by the state. That week the chorale will not be here on Thursday and Friday, so if you are in chorale, please plan ahead with me so that you don’t get behind.
This Week in Physics
We will begin the electrostatics unit. For our first day of class together this week (whichever day that is for your class period,) please take notes on the following podcasts: Podcast 1 – Introduction to Charge and Podcast 2 – Conductors, Insulators, and Charging. We will go over these in class and do some experimentation with creating electrostatic charge, and then we will do assignment 1. When we finish assignment 1, plan for a quiz the following day and also take notes on Podcast 3 – Electric Force. That oughta do it for the week.
This Week in Astronomy
On Monday we will tie up a few loose ends with the sun unit and will then start to take a look at the moon. We don’t see each other on Tuesday or Thursday, so our sun unit test will be on Wednesday. On Wednesday your Unit 2 – Homework Questions are due, as well. We’ll spend the rest of our time researching the appearance and visibility times of the moon through one lunar cycle. Now that your unit 1 outdoor lab is done, you’re ready for the unit 2 outdoor lab. This lab requires multiple observations made at the same time of day many days apart. You’ll need to start NOW in order to finish on time. It is due on Friday, April 17.
Cool Science of the Week
It’s going to RAIN this week..not snow, but rain! That’s oddly awesome! A lot of people (myself included) love the smell of rain, but have you ever wondered, “Why does rain smell?” I mean, it’s just water, right? Well, researchers at MIT may have figured out the answer to the question. Apparently as raindrops hit soil, small amounts of gas hovering above the soil get sort of smashed into the rain drop, where they then bubble out (like a in a glass of pop.) This disperses into the air the scent-filled layer of gas that usually just sits on the soil. Cool!
In the top row you can see the raindrop colliding and then forming bubbles. In the bottom row you can see the bubbles bursting.
