Week of February 27, 2017

There are four more weeks until the end of the third quarter, and March starts this week. Time is flying by!

This Week on Physics
On Monday we will take a quiz over goal set 2 (classifying collisions based on system kinetic energy.) Also for Monday please take notes on PODCAST 3: The Impulse-Momentum Theorem. We will discuss this podcast in class and will then analyze impulse and momentum change data through the Impulse-Momentum Theorem Lab. After that we will do  assignment 4. Expect the momentum unit test by the end of this week or (more likely) early next week.

Cool Science of the Week
This week NASA announced the discovery of a solar system a mere 40 light years away (relatively close) that has SEVEN small, rocky planets, three of which are in the “habitable zone,” the region around a star in which a planet could have liquid water and a temperate climate and could, therefore, harbor life.* The system is called TRAPPIST-1, and the planets are so close together that if you lived on one, you’d be able to see other planets in the sky in such detail that you could see their atmospheres! Scientists’ next step is to analyze chemical signatures of the planets to determine if they have water along with other chemical conditions required by Earth-like life forms. Video link

Do you think if you lived there you’d take vacations from one planet to another?

*Given how close they are to the star, the intensity of the star’s radiation, and the potential for atmospheric composition, all seven could have liquid water!

 

 

Week of February 20, 2017

This will be a short week as we observe Presidents’ Day on Monday.

This Week in Physics
If you have not already done so (which would have been a mistake 😉 ) please take notes on PODCAST 2: Types of Collisions – The role of kinetic energy by Tuesday. We will go over the different types of collisions with an analysis of system kinetic energy and will then do assignment 3 together in class followed by a quiz over goal set 2 as announced. That should fill up our week, although it is possible that we will assign PODCAST 3: The Impulse-Momentum Theorem for Friday. ~*Due on Wednesday*~ Your Conservation of Momentum lab report is due on Wednesday (postponed from Friday the 17th.) A hard copy is due at the start of class, and an upload to TurnItIn.com is due by 3:00 on that day. Use our writing guides to organize and create your reports properly: Lab Report Writing Guide and Lab Report Rubric. As always, you must write while logged into your Google account on a shared Google Drive document. You must share your document with me as an editor. Use this email address: burgessm@alstudent.org.

Cool Science of the Week
About a decade ago the BBC set viewership records with its series Planet Earth. Known for its extraordinary photography and storytelling, the show has finally returned with Planet Earth 2, filmed in ultra HD. Here’s a preview as a young sloth goes in search of love (awww!!!) The series premiers this Saturday, February 18th at 9:00 on BBC America.

Happy Valentine’s Day!!! <3

This Week in Physics
On Monday we will take a quiz over momentum goal sets 1 & 2. Next we will crunch numbers from our  momentum lab and analyze the role of kinetic energy in the two types of collisions we explored. When announced please take notes on PODCAST 2: Types of Collisions – The role of kinetic energy. Important notes:
~*1*~ This is course recommendation week, so expect significant disruptions to our physics work as we explore your many options for next year. I will conference with each of you individually to help you make informed decisions. Please spend some time looking through our Program of Studies. As seniors you will have more choices than ever before, and it’s worth taking time now to ensure that your senior year will be both productive and enjoyable.
~*2*~ Your Conservation of Momentum lab report is due on Friday. A hard copy is due at the start of class, and an upload to TurnItIn.com is due by 3:00 on that day. Use our writing guides to organize and create your reports properly: Lab Report Writing Guide and Lab Report Rubric. As always, you must write while logged into your Google account on a shared Google Drive document.

Cool Science of the Week
Did he flop? (link) The physics of inertia, energy, and momentum holds the answer! (Hint: Look at the inertia and momentum of the lower half of LeBron’s body when Draymond Green so viciously attacks him)
P.S. LeBron is the GOAT

Week of February 6, 2017

This Week in Physics
We will complete assignment 1 & 2 on momentum and will take a quiz on goal set 1 when announced. Next up we’ll analyze system momentum experimentally by doing the Conservation of Momentum Lab. If/when announced, please take notes on PODCAST 2: Types of Collisions – The role of kinetic energy.
The Conservation of Energy Lab is due on Thursday. A hard copy is due at the start of class, and an upload to TurnItIn.com is due by 3:00 on that day. Use our writing guides to organize and create your reports properly: Lab Report Writing Guide and Lab Report Rubric. As always, you must write while logged into your Google account on a shared Google Drive document.

Cool Science of the Week
In honor of our snow day, here’s some LITERALLY cool science that takes you on a “Snowflake Safari” to discover whether the old adage is true that no two snowflakes are alike.
