Week of September 25, 2017

We are fully into the last half of first quarter, so be sure to pay attention to PowerSchool to check that your assignments are complete and up-to-date.

This Week in Physics
For Monday complete Goal Set 3 in your goal packet. We will go over this and take a quiz over these goals by the end of the period on Monday. For Tuesday take notes on PODCAST 4: Kinematic Equations and Free Fall but stop at 8:52 (where the topic of free fall begins.) We will go over this on Tuesday and Wednesday and complete assignment 3 together in class, followed by a quiz, as announced. When announced please take notes on the remainder of Podcast 4.
NOTE: For 8th and 11th periods…Follow these instructions except that your Goal Set 3 quiz will be Tuesday.

Cool Science of the Week
As icebergs melt and break apart due to climate change, researchers standing on the ice can feel vibrations under their feet. They have recently recorded those vibrations and realized that the icebergs are making sounds! Played at high speed, the sounds make a strange, eerie music. Listen here!


Close Look at a Crack on Larsen C
The rift in this iceberg is about three football fields wide and runs all the way through to the bottom of the iceberg. When it finally breaks off, it will be the size of Delaware.

Week of September 18, 2017

This Wednesday we have a late start, and classes will begin at 8:45. In addition, please be certain to check the schedule of Princeton Review pull-out sessions, which begin on Wednesday.

This Week in Physics
On Monday we will continue to experiment with acceleration in order to examine its effects on motion. This will include graph analysis and analysis of signs. We will then complete assignment 2 together in class followed by a quiz, as announced. By the end of the week you may be asked to take notes on Podcast 4: Kinematic Equations and Free Fall.

Cool Science of the Week
Twenty years ago NASA sent the Cassini space probe on a mission to Saturn. After visiting Saturn’s moons, flying through its rings multiple times, and taking atmospheric data, NASA today sent Cassini plummeting down into Saturn’s gaseous body where Cassini would be crushed to oblivion. On its way dowm it sent back to us information about Saturn’s surface and gravitational forces. Pretty amazing!

Week of September 11, 2017

On Monday we will have a special bell schedule to allow us to participate in an important presentation in observance of 9/11. In addition, we will have a special bell schedule on Wednesday, September 13, as the juniors will take a practice PSAT.

This Week in Physics
On Monday (and possibly Tuesday) we will complete assignment 1 from unit 1 together in class, so please be sure to bring your textbooks. (Note: 8th period has this assignment DUE on Monday.) On the day after we finish this assignment, we will take a quiz over learning goals sets 1 and 2. (Note: 8th period won’t have this quiz until Tuesday.) We will then begin to experiment with accelerated motion as we explore learning goal set 3. To prepare for this, please watch Podcast 3: Acceleration by the date announced in class, most likely Tuesday or Wednesday. Time permitting we will work on assignment 2 from unit 1, but this may carry over into next week. 

A hard copy of your lab report for the uniform motion lab is due at the start of your class period this Wednesday, September 13. All documents needed to write the lab can be found in last week’s blog entry. 

Finally, every student needs to add this class to her or his TurnItIn.com account by Tuesday at the start of your class period. The class ID and enrollment key are below. We will discuss in class how you should use the website. (Don’t forget to check out the Cool Science of the Week below.)

Cool Science of the Week
As the Western Hemisphere deals with so many horrible and tragic hurricanes, you can track the winds with this real-time
world wind map and this United States wind map. Both are pretty amazing.


Week of September 4, 2017

Remember to take Monday off to “honor the American labor movement and the contributions that workers have made to the strength, prosperity, laws and well-being of the country.

This Week in Physics
If you have not yet subscribed to this blog, you should. Look on the right side of this page (if you’re on a computer) or scroll to the bottom (if you’re on a phone) to find the subscription link. If you have not yet subscribed to Remind for this class, text @shellyburg to 81010. Read on…

For Tuesday please take notes on Unit 1 Podcast 2: Interpreting Graphs of Position v Time. (Remember that your podcast notes go in a notebook, not your composition book, although you need to bring both books to class.) We will debrief this in class as well as tie in the discoveries we made while doing our uniform motion experiment. We will also progress through some graph interpretation activities using the Moving Man application from PhET.

As the week progresses we will spend time in the media center learning how to write lab reports for this course. It is essential that you can log into your @alstudent.org account in order to work on the report, so be sure you have confirmed your login information before class on Wednesday. Your lab report for this class is due next Wednesday, September 13 at the start of your class period. Documents you will need to write the lab report are:

 

Cool Science of the Week
Imagine finding out that someone invented an iPhone long, long ago…A similar thing has just happened to mathematicians! We have long regarded Greek astronomer Hipparchus to have been the founder of trigonometry in 120 BC, but researchers have finally decoded a stone tablet found in the early 1900s (by the guy who was the inspiration for Indiana Jones!), and it turns out this tablet shows that trigonometry was founded long before Hipparchus did his work…3700 years ago around the year 1700 BC in Babylon! That’s 1900 years earlier in a totally different part of the world! (The tablet, known as Plimpton 332, was found in Babylon’s ruins near Baghdad, Iraq. Babylon was a major city in ancient Mesopotamia.)To mathematicians and scientists, this discovery is like finding out someone invented an iPhone 1900 years ago in the year 100 CE!
