There are two weeks left to third quarter. Heads up! 🙂 Also, as you know, our schedule will be a smidge topsy-turvey due to the SAT administration for all juniors on Wednesday morning.
This Week in Physics For Monday completeassignment 3. If you are in first or third period, please also completegoal set 3. We will take the momentum unit test on Tuesday or Thursday as announced in your class period. Then we will complete theImpulse-Momentum Theorem Lab. (This experiment will result in a gorgeous lab report… yay!)
Cool Science of the Week Silent space: Did you know that every science fiction movie that allows you to hear a blast is boldly lying to you? Sound waves need a medium to travel through, so in the vacuum of outer space, there’s no sound…or is there? A plasma physicist has discovered that charged particles interact with Earth’s magnetosphere to create a different kind of sound wave, a magnetosonic wave. These waves are very low in pressure and are therefore undetectable, but they can affect satellites. Below the awesome gif is an audio file that makes these space sounds audible by condensing a year’s worth of sound into six minutes. Check it out!
On the audio below, click on the white lines in the lower right to hear the sounds after clicking the play button in the top left. Alternately you can click here to access the researcher’s external site.
This Week in Physics We lost a lot of time last week due to scheduling, and each section has different starting points for the week. Therefore please follow the announcements for your particular class section regarding when each of the following will be due. (Your class period may have already done some of these.)
Cool Science of Last Week Last week Elon Musk‘s SpaceX launched a new rocket model into space. The Falcon Heavy rocket has the cool feature of returning its rocket boosters back to Earth in a way that allows them to land for reuse. You can check out their synchronized landing at the end of the short video clip below – so cool! Also super cool: The Falcon Heavy, while in space, released into an orbit around the sun a Tesla Roadster, an electric car from Mr. Musk’s other company, Tesla. In the Roadster: an astronaut mannequin named Starman. On the dashboard: a sign that says “Don’t Panic.” Music playing in the car: Starman by David Bowie, natch. Bonus trivia: For how long could the mennequin hear the song play (if the mannequin could hear)? Bonus bonus trivia trivia: Elon Musk was the inspiration for the movie version of which fictional character? (Bonus trivia is worth only the bonus of fame and glory, not points. 🙂 ) The following is a real picture! Ridic!
This Week in Physics For Monday please complete assignment 1. In class on Monday we will go over assignment 1 and will put the finishing touches on our law of conservation of momentum experiment. On Tuesday we will take a quiz over goal set 1. (If your class does not finish going over goal set 1 in class on Monday it will be due on Tuesday.) As announced please take notes on PODCAST 2: Types of Collisions – The role of kinetic energy. We will complete assignment 2 and will reprocess our data from our mini law of conservation of momentum lab from the perspective of analyzing the types of collisions. By the end of the week we will take a quiz over goal set 2. We may be ready to take notes on the last podcast of the unit by Friday, but with scheduling for next school year taking place this week, it is likely that you will take notes on that for next week. Stay tuned!
Cool Science of the Week We’ve been discussing conservation of mechanical energy. A type of energy we don’t cover in class deals with the rotational motion of objects. This is called rotational kinetic energy, and a system’s initial mechanical energy can convert to rotational kinetic energy as well as straight-line (“translational”) kinetic energy. Engineers have put this concept to good use by creating rolling traffic barriersthat take the translational kinetic energy of vehicles and convert some of it to the rotational kinetic energy of rolling barrels inside of the barriers. This helps slow the cars down more than rigid barriers. Pretty cool use of simple physics!
Welcome to our first five-day week of school since the week of December 11! (wow!) We will have guest speakers from the TEE program on Friday, so if you have an interest in TEE, be sure to make an extra effort to be in class on that day.
This Week in Physics
We will discuss our results from theWork-Energy Theorem Experiment. The lab report will be due next week on Tuesday, January 30 at the start of your class period. You must share your Google document with me at my Gmail address, not my school email address. You must then upload your document toTurnItIn.comby 3:00 p.m. on the due date. The class ID is 16214937, and the password to join the class is Tesla.
Cool Science of the Week Who doesn’t love adorable sea turtles? They’re precious, right? Almost every species of sea turtle is also endangered, and their plight has hit a serious hurdle by way of climate change. The sex of a hatchling sea turtle depends on the temperature of the sand during incubation, andwith rising global temperatures, 99% of the recently hatched green sea turtles are female! Obviously that’s a big problem for future generations of sea turtles. Sad! “Not cool, dude!”
This Week on Physics For Tuesday please complete Unit 4assignment 1andgoal set 1. (Both are due at the start of class on Tuesday.) We will take a quiz over goal set 1 on Wednesday or Thursday, as announced in class. For Wednesday please take notes onPODCAST 2: Work-Energy Theorem. We will go over this and will then doassignment 2. Time-permitting we will perform theWork-Energy Theorem experiment. (If we don’t get to it this week, we will do it next week.)
Cool Science of the Week I don’t know about you, but when it’s as cold outside as it’s been lately, I love to comfort myself with a nice, sugary, hot beverage. One chilly day in 2016 an engineer poured himself a latte and discovered a strange phenomenon:The latte formed striped layers! Being an engineer he used his scientific resources to figure out why and ultimately discovered that lattes can undergo a process that involves both fluid mechanics and thermodynamics, a process called double-diffusive convection. This process is similar to the one that creates the weird hot/cold layers that freak you out when you swim in Lake Erie!
