The sun entered a total eclipse over South America for a few minutes 🌤️.
Total solar eclipses occur when the New Moon comes between the Sun and Earth and casts the darkest part of its shadow, the umbra, on Earth. A full solar eclipse, known as totality, is almost as dark as night. A total eclipse is spectacular to see.
The chemical traffic light is a stunning colorful reaction! The experiment involves changing colors with an indicator – indigo carmine in an alkaline solution of glucose. The alkaline solution of glucose is poured into a solution of indigo carmine, and we observe a gradual change of color: blue – green – red – yellow. We can reverse the reaction simply by shaking the solution. The indigo carmine is oxidized by the oxygen in the air and the colors change in the opposite direction.
Initially, the solution colored by the indigo carmine (blue) is oxidized by the oxygen in the air to a green color – this is the color of its oxidized form. When the green solution is left to stand, the glucose begins to reduce the indigo carmine, first to red, and then to yellow. If you shake the solution or decant it, it mixes with air, and the oxygen once more oxidizes it. to green.
Jupiter’s volcanically active moon Io casts its shadow on the planet in this dramatic image from NASA’s Juno spacecraft. As with solar eclipses on the Earth, within the dark circle racing across Jupiter’s cloud tops one would witness a full solar eclipse as Io passes in front of the Sun.
Such events occur frequently on Jupiter because it is a large planet with many moons. In addition, unlike most other planets in our solar system, Jupiter’s axis is not highly tilted relative to its orbit, so the Sun never strays far from Jupiter’s equatorial plane (+/- 3 degrees). This means Jupiter’s moons regularly cast their shadows on the planet throughout its year.
Juno’s close proximity to Jupiter provides an exceptional fish-eye view, showing a small fraction near the planet’s equator. The shadow is about 2,200 miles (3,600 kilometers) wide, approximately the same width as Io, but appears much larger relative to Jupiter.
A little larger than Earth’s Moon, Io is perhaps most famous for its many active volcanoes, often caught lofting fountains of ejecta well above its thin atmosphere.
🔴 Measles is a fairly uncommon disease in the UK now because most people are vaccinated against it when they are young children.
It causes a red, blotchy rash, a raised temperature and sneezing & coughing. In some cases, it can lead to complications including infections of the lungs and brain which can be life-threatening.
This is one of the 7 diseases on the spec that you need to know for AQA GCSE Biology & Combined Science. Learn about them all using my revision videos on YouTube - link to my channel is in my bio!

Liquid Nitrogen + Boiling water = Water Vapour explosion 💥
When you pour the liquid nitrogen into water, you get a big burst of mist, frantic boiling (the liquid nitrogen, not the water!), and a wash of fog pouring from the water container. It's a lot easier to get dry ice than it is to get liquid nitrogen.
Kesler Science Stations on Ecosystems today. Kids were busy the whole class period learning about biotic and abiotic factors in ecosystems. Great day of Learning at Le Mars Middle School! #LeMarsLearns#ScienceRocks

I’m super sad that being on maternity leave during December means I’m missing the school door decorating contest (it’s my fav 👏🏼) but I guess that gives other teachers a chance to win 😆 Here is my door the past three years 👏🏼🎅🏽🎄
@ashlee_stood’s little guy Hudson is sharpening his science skils, and having a blast doing it! We love to see young talent at work, and we love that our Loop Lab subscription box can help him get there 👨🔬 Tap the link in our bio to order yours today!
Students in Mrs.C.Smith’s CP Earth Science classes participated in a Rock Cycle Review with the Breakout EDU called “Solid as a Rock”. Students reviewed for their Midterm exam while cooperating and working together to gather clues in order to stop Dr. Stone’s plans to use his “laser” on international monuments. #AllMeansAll#ScienceRocks
