With Thanksgiving vacation coming, we only have two days during the week of November 21, so this entry covers the week of November 28, as well.
These Weeks in Physics Morning classes: Your quiz over elastic force is on Monday. (Keep reading.) Afternoon classes: Do assignment 3as homework, due Monday 11/21 at the start of class. (8th/9th, you are basically done. Just be sure you’ve got it 100% complete.) Your quiz over elastic force will be Tuesday. (Keep reading.) Morning classes: Please take notes on PODCAST 4: Newton’s Laws of Motion – First Law (Inertia)for Monday. (Keep reading.) Afternoon classes: This podcast is due for you on Tueday. (Keep reading.) All classes: We will discuss this podcast in class and will then completeassignment 4 together followed by a quiz as announced. When announced please take notes onPODCAST 5: Newton’s Laws of Motion – Second Law. We will discuss this in class and will then complete an activity andassignment 5together followed by a quiz as announced. As discussed in class, we are delaying the friction lab until right after Thanksgiving break so that it’s fresh in your minds while you write the lab report. Expect to do this experiment on Monday or Tuesday upon returning, with a formal lab report due the following week.
Cool Science of these Weeks 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…some of the same physics we’ve been learning, in fact! Here’s a short video fromScience 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 alittle more informationand a couple of awesome pictures.
The following document sums up the debrief we did in class regarding the lab. You can use it to guide your writing: Human Cannonball Lab
As always, you must write while logged onto you Google account on a shared Google Drive document. You must share your document with me as an editor. Use this email address: firstname.lastname@example.org.
As always, you must upload your lab report to TurnItIn.com by 3:00 on the day the lab is due (Wednesday.)
Now onto the rest of the week… By Monday be sure you’ve taken notes onPodcast 2: Friction. We will discuss this podcast and then doassignment 2together followed by a quiz on the day after we do the assignment. Next we will perform theFriction Lab. This will take us toward the end of the week. If announced, please take notes on Podcast 3: Elastic Force.
Cool Science of the Week How can there be a lake, nicknamed theJaccuzi of Despair, under the Gulf of Mexico? Density, of course! About 100 feet wide and 12 feet at its deepest, this dense brine liquid contains such a lethal does of salt that anything that accidentally swims into it dies a painful death. 🙁 The liquid that makes up the lake is so much denser than the salt water above it that it has sunk almost 4000 feet to the bottom of the Gulf. (P.S. Animal lovers, don’t worry…The fish makes it!)
There are only two weeks and two days until Thanksgiving break…Can you believe it???
This Week in Physics For Monday please take notes onUnit 3 Podcast 1: Net External Force, Weight, and Normal Force.We will go over these in class and then do assignment 1followed by a quiz on the day after we finish that assignment. When announced, please take notes onUnit 3 Podcast 2: Friction. We will go over these in class and then doassignment 2followed by a quiz on the day after we finish that assignment. This will prep us for ourFriction Lab, which will lead us to a formal lab report. Speaking of formal lab reports: Your formal lab report for theunit 2 projectiles lab is due for 1st period and 4th period classes on Thursday, November 10. The 8th and 11th period classes have this lab due on Monday, November 14. Remember these key requirements: ** You and your writing partner must each write under your own Google account using a shared document. ** You must also share this document with me as an editor, not a viewer at email@example.com. (Note that this is a new email address.) ** You must upload your finished lab report toTurnItIn.comby 3:00 on the due date. ** Be sure to follow all instructions given in class regarding lab report content and format.
Cool Science of the Week This past week we discussed the behavior of orbiting objects as projectile motion. We also discussed what happens if the horizontal velocity component is too small to create an orbit. Here’s a “fun” simulator from Purdue University to play with to see what would happen if asteroids of various densities, sizes, velocities, and impact angles were to hit Earth. Given that this is what scientists are confident caused the extinction of the dinosaurs, this adds up to one interesting website!
