Rocks become more than just your everyday rocks when looking under a petrographic microscope. Videos show how polarized light travels through basalt, schist, marble, and limestone.

Incredible watching this time lapse!

[NOAA Satellites @NOAASatellites]

Happy #FullDiskFriday! Tomorrow at 2:50 am ET, astronomical #autumn officially begins in the Northern Hemisphere!🥳🍂

To celebrate, here is a time-lapse from @NOAA's #GOESEast 🛰️ showing the change in the angle of the sun from last year’s #equinox through today.

[Stephanie Sarmiento @sarmsci]

Thanks so much! It's great to connect with you!

[Ann Kozma @annkozma723]

@sarmsci @MicrosoftFlip Hi Stephanie! I'm Ann from the @MicrosoftFlip Team - just wanted to say glad to get connected! I love seeing your tweet -- we are so glad that YOU are part of the #Flipsider family! Give us a shout if we can help in any way... hope you're having a great week! 💗

It's fascinating to learn more about what sparked the Quebec wildfires!

[Instant Weather Ontario ⚡️ @IWeatherON]

"How did the Quebec wildfires start all at once?!" is a question we've been receiving quite a bit.

We were curious too so we decided to review the data. Using GOES-16 satellite data for fire hotspots and by overlay lightning data, the answer becomes pretty clear.

Of course, not all fires are caused by lightning. In rare cases, they can be caused by human negligence such as a bonfire that has gotten out of control, improperly disposed ashes, lit cigarette butts and even arson.

Nevertheless, you can review the data yourself at: https://t.co/vlGbS1sofj

Graduation rehearsal for the class of 2023! This year has flown by! So proud of all of their accomplishments! @TJHSST_Official

[Stephanie Sarmiento @sarmsci]

Thank you @MicrosoftFlip for letting me join the Flip Insider program! Can't wait to learn about what's coming down the pipeline with Flip! #Flipsider

[Stephanie Sarmiento @sarmsci]

That's pretty incredible. And here I thought conditions in the DC area were bad!

[National Weather Service @NWS]

No. This is not Mars.

This was taken at the NWS forecast office in Binghamton, NY, where the current air quality due to smoke from wildfires in Canada is in the "Very Unhealthy" category.

We ended Geosystems by creating concept sketches of what we learned this year. There were a lot of "ah-hah" moments as we realized just how much Earth's spheres are connected to one another and to ourselves. A true illustration of Earth as a system! @TJHSST_Official

[Stephanie Sarmiento @sarmsci]

40 TJ seniors spent their Saturday collecting rock & fossil samples dating back to 500-300 mya in Corridor H. Such an amazing experience thanks to a grant from the NSF and Prof Gilleaudeau of GMU and Prof Kaufman of UMD. Ty for a memorable time! @TJHSST_Official

We did one of my favorite labs that looks at water masses and how they situate themselves in the ocean. This group got one of the best visual results. You can clearly see 4 layers of water.

[Stephanie Sarmiento @sarmsci]

This is hands-down, one of my favorite labs, it clearly illustrates how water masses will stratify based on density. Students love it, too! I'm planning on sneaking it into the TJ geosystems curriculum.

[Elizabeth Wood @SciTeacherWood]

Oceanography students modeled density currents with dyed water at different temperatures and salinities! @apsvirginia @generalspride @APSscience @APS_STEM Huge thanks to my Oceanography predecessor @sarmsci for this cool activity! #GeneralsSci @Principal_WLHS @WLHSAsstPrinPJ

[Stephanie Sarmiento @sarmsci]

Celebrating the year of the rabbit at TJHSST. May the year provide us with peace, hope, and prosperity! @TJHSST_Official

[Stephanie Sarmiento @sarmsci]

Why stand & lecture, when students can collaborate on understanding big ideas? TJHSST students loved walking around the room to learn more about & draw connections among an array of topics related to geosystems. The feedback was motivating! @FCPSScience

[International Space Station @Space_Station]

Active volcanoes are easy to spot from the space station and are frequently photographed by astronauts during an orbital flyover. More Earth pix... https://t.co/qcHlvByj8M

[Stephanie Sarmiento @sarmsci]

Geosystems goes up to eleven as we visit a local stream to study rocks and stream features.

This coming week, Earth passes closer to Jupiter than in six decades.

Rising at sunset & setting at sunrise, look for it overnight — the brightest "star" in the sky.

Jupiter, at its closest, exerts a force of gravity on Earth 5x higher than when at its farthest

[Stephanie Sarmiento @sarmsci]

So proud of you, Lourdes!! This is so well-deserved. Congratulations!

[Francisco Durán, Ed.D. @SuptDuran]

Congratulations to Washington-Liberty Science Teacher Lourdes Sotomayor for being an #APSAllStar who does innovative hands-on labs & who decorates her room with posters of scientists of all backgrounds & ethnicities so her students can see themselves as scientists! @GeneralsPride

[Stephanie Sarmiento @sarmsci]

The next wave of mind-blowing images of the universe is upon us! Almost every spot in this picture is a galaxy!

[NASA @NASA]

It's here–the deepest, sharpest infrared view of the universe to date: Webb's First Deep Field.

Previewed by @POTUS on July 11, it shows galaxies once invisible to us. The full set of @NASAWebb's first full-color images & data will be revealed July 12: https://t.co/63zxpNDi4I

[Stephanie Sarmiento @sarmsci]

@aims107 Thank you so much! It's been bittersweet leaving W-L, but I'm excited for this next step.

[Stephanie Sarmiento @sarmsci]

It has been such a joy teaching at W-L for the past 11 years. A new adventure awaits for me at TJHSST next school year.
