Congratulations on making it through the drudgery of the first week! Now let’s have some FUN! (*Reminder to former students receiving this in email form…There is an unsubscribe link at the bottom of the email.)
This Week in Physics
1.) Please be sure to subscribe to this blog. If you choose not to, you’ll need to return to sgbscience.net every Friday to learn about your future.
2.) Please sign up for our Remind.com.
3.) If you did not turn in the signature page from our Course Policies and Procedures document, please be sure to do so this week.
4.) Assignments: By Monday please do two things:
****** First, please view the “How to Do Conversions in Physics” podcast on the
How Do I…? page of our website. I expect you to be proficient in doing conversions, and this method helps. If you need extra practice, you can (optionally) do the section on conversions on our Extra Math Help practice page and check your work with me. You also need to be fluent in writing and reading scientific notation. If you need extra help with that, the math help practice page also has a section on that topic along with resources. Feel free to try those problems and check your work with me.
****** Second, please take notes on Motion in One Dimension Podcast 1 – Distance v. Displacement, Motion in One Dimension Podcast 2 – Displacement & Direction, and Motion in One Dimension Podcast 3 – Speed vs. Velocity. We will go over these and will then dive into a short activity that will lead up to our first lab, which we’ll begin most likely mid-week. (Your lab report won’t be due until we’ve gone over how to write our lab reports.) It is possible that by the end of the week you may need to take notes on Podcast 4 – Slope of Position vs. Time Equals Velocity, but please do not do so until AFTER we finish the lab. (It contains secrets!)
Cool Science of the Week
One of the most fascinating areas in astronomy today is the search for exoplanets, or planets outside of our solar system. To date, we have discovered 3,374 exoplanets, 570 multi-planet solar systems, and 4.696 additional planet candidates. One of the questions scientists seek to answer about each new planet discovered is how similar the planet is to Earth. Most planets are too hot or too cold or too gassy to be considered as candidates for life or human exploration, but some planets are in the “Goldilocks Zone” with temperatures that could support liquid water, an essential ingredient for the kind of life forms we have on Earth. Amazingly, scientists this week announced the discovery of an Earth-like planet in the Goldilocks Zone around not some distant star but orbiting the CLOSEST star to us! The very short video below will tell you more.
This second 33-second video shows you what it would look like if you took a spaceship on the 4.25 light year (24,946,282,800,000 mile) journey to the planet. Happy travels!
Disclaimer: It would take more than 33 seconds to travel there. LOL
