  • The harder you shake, the more it changes colour.

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.

Citizen scientist Kevin M. Gill created this enhanced-color image using data from the spacecraft's JunoCam imager. The raw image was taken on Sept. 11, 2019 at 8:41 p.m. PDT (11:41 p.m. EDT) as the Juno spacecraft performed its 22nd close flyby of Jupiter. ➖➖➖➖➖➖➖➖➖➖➖➖➖➖

  • 🔴 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!
✰
Or visit www.emmatheteachie.com & go to the video section > infection & response.

  • You might have heard that humans share 50% of their dna with bananas, but did you know that we also share: 96% with chimps, 90% with cats, 85% with mice, and 61% with fruit flies!

  • 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 👏🏼🎅🏽🎄

  • 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
