Cool Science of the Week
Meet the Balloonatics! This is the team of people who engineer the balloons for the Macy’s Thanksgiving Day parade, and believe it or not, they use PHYSICS! It’s some of the same physics we’ve been learning, in fact! Here’s a short video from Science Friday that shows you how it’s done! Below the video I’ve included the science of cranberries, which I think is really cool.

The science of CRANBERRIES! I don’t know about you, but I LOVE to make homemade cranberry sauce for Thanksgiving. Did you know that cranberries are grown in BOGS? They’re grown on vines like strawberries, but they thrive if those vines are planted in wetlands. That’s cool. Also, 60% of our cranberries come from Wisconsin, while 25% come from Massachusetts, and if you have the chance to head out to those states, you can go to a cranberry farm (like we go to blueberry, raspberry, and strawberry farms here.) Here’s a little more information and a couple of awesome pictures.

Week of November 16, 2015

Hello again, intrepid physicists! It’s almost Thanksgiving, and interims are this Friday. Keep going strong!
Please note: Email continues to be down as of the writing of this blog (Friday the 13th.) If you need to contact me, please call the school and use my extension, which is 1262.

This Week in AP Physics
We will continue with momentum (ha ha) by completing our impulse-momentum theorem lab, homework, and classwork followed by a possible quiz. Next we’ll cover the law of conservation of momentum and will perform an experiment, do a small homework, and do some classwork followed by a possible quiz. Finally we will cover the role of energy in collisions and will do an additional experiment. I’d love to finish all of this by next Tuesday, but it might take some luck. 🙂

This Week in Physics
Please look at your class period…
1st period: On Monday we will take a quiz on friction. Then we will finish our friction experiment (including making up the lab for all of those who were out on Thursday) and will also finish covering elastic force, followed by assignment 3. On the day after we finish assignment 3 we will take a quiz and will then begin to explore Newton’s Laws of Motion.
3rd period: On Monday we will finish assignment 1 from unit 3 followed by a quiz on Tuesday. On Monday we will also take a podcast quiz over Force Podcast 4 – Introduction to FrictionForce Podcast 5 – Static Friction, and Force Podcast 6 – Kinetic Friction, so be sure to take notes on those. We will then do an experiment on friction for which you will write a lab report on the projectile experiment is due on Wednesday, November 18. We will also do assignment 2 followed by a quiz as announced. Time permitting, if announced, please take notes on Force Podcast 7 – Elastic Force and Force Podcast 8 – Elastic Force Sample Problems. Final note: Your lab report for the projectile experiment is due on Wednesday, November 18. (Remember that the hardcopy will be due at the start of class on the due date; an upload  is due to TurnItIn.com by 3:00 of that day.

We will go over these and will then do assignment 3 followed by a quiz, as announced.

Cool Science of the Week
It’s tough to see things that are really far away in space unless they glow. Stars and galaxies are fairly easy to spot using space telescopes, but planets are another matter (physics pun!) Astronomers theorize that our solar system extends outward to an giant icy asteroid belt called the Oort cloud, but we’ve never seen anything in the Oort cloud directly. However, this week astronomers in Hawaii announced that they’ve seen a dwarf planet that is the most distant object we’ve yet detected in our solar system. It is 103 times as far away from the sun as Earth is, and it is 3.5 times farther from the sun than Neptune! It is dwarf planet V774104, but the astronomer who discovered it is in the process of deciding on a better name, possibly the name of a deity from Hawaiian culture. What does this have to do with the aforementioned Oort cloud? It is possible that this planet’s orbit takes it into the Oort cloud, making it the first object we have direct evidence of that exists in the asteroid belt that has, up to this point, been theoretical.


The Oort cloud is theorized to be up to 100,000 times the Earth-Sun distance WIDE! Imagine the distance from Earth to the Sun and multiply it by 100,000…That’s how big we think the Oort cloud is! The tiny white dot in the center of the cloud on the image above is our entire inner solar system (as far out as Neptune)!

Week of November 9, 2015

Welcome to the third week of second quarter! Interims are just around the corner, and time is flying by!

This Week in AP Physics
On Monday we will take our test over our energy unit. On Tuesday we continue forward with momentum (ha ha.) Expect to do homework 1 and our first lab (on the impulse-momentum theorem) by the end of the week. Be cheerful: This unit has much shorter homeworks, and it integrates a lot of our previous topics, so it will feel a little better to you. 🙂

This Week in Physics
We will finish debriefing our introductory podcasts on forces, weight, and normal force and will finish assignment 1. (Note: 3rd period should take notes on those podcasts for Monday.) There will be a quiz over these topics on the day after we finish the assignment. Also due on the day after the assignment are your notes on the friction podcasts: Force Podcast 4 – Introduction to FrictionForce Podcast 5 – Static Friction, and Force Podcast 6 – Kinetic Friction. We will go over these in class and will then do an experiment on friction for which you will write a lab report (due when announced.) We will also do assignment 2 if we have time, but most likely it will spill into next week. 3rd period note:  Your lab report for the Human Cannonball Projectiles Lab is due on Monday, November 16. (Remember that the hardcopy will be due at the start of class on the due date; an upload  is due to TurnItIn.com by 3:00 of that day. Remember to write using Google Drive and share your document with me at alhsgb@gmail.com…Note that I do not use that for email correspondence.

Cool Science of the Week
We are in a shower! A meteor shower, that is…Earth is currently passing through the debris left behind by Comet Encke, which last passed us by in October 2013. A comet is like a party that leaves all of its trash behind, and that trash consists of rocks and dust. When we pass through that garbage heap, some of those rocks become meteors that enter our atmosphere at high speeds. As they encounter ever-thickening atmosphere on their way down, friction causes them to heat up and burn, appearing as bright streaks in the sky. (There is no such thing as a shooting star; even as stars move, they are too far away for us to detect their paths. What we call shooting stars are really meteors burning up upon entering our atmosphere.) If you’d like to see this Taurid meteor shower (named after the constellation Taurus from which many of the meteors appear to emanate,) go out any night this week. Your best bet (barring clouds) is to go out on the night of November 11th: The meteor shower will be peaking, and we will have a new moon (i.e., the moon will not be up at night.) The best viewing times are the hours just after midnight, but if you go out at any time and are patient, you could see up to ten “shooting stars” an hour. Fireworks for Veteran’s Day! Get a lawn chair and a blanket and have fun!
