Hon Chemistry 11-10-21 Using Chemical Formulas

HON CHEMISTRY: So the little mole turns out to be a pretty big deal – and a very handy tool!!

Great job today! Here’s discussion on formula mass and molar mass, and then using molar mass and Avogadro’s number as a conversion factor. You’ve got a couple of great tools – so now think through the problems and go forth and conquer!! Be sure and practice them so you don’t forget!

  1. STEM-This week I researched how flamingos have a certain type of serum they produce called carotenoid that allows their feathers to maintain their red/pink color. The flamingos need this color to attract mates and without the carotenoid, the color of their feathers fade. Scientist studying found that feathers that were out in the sun fade much faster than feathers that are not exposed to the sun.

  2. STEM- Today I researched pearls and how they form such perfect spheres. The research showed that the mollusks self-adjust and can determine how thick or thin a layer needs to be on a certain place on the “pearl-in-progress” They propose that we can one day apply them as a new generation of “super material”,maybe in satellites or military use.

    • Stem- I researched the process of how pearls are made and how they are produced into a perfect sphere. It happens whenever an irritant gets inside of the mollusk, the mollusk produces a layer of nacre which protects the mollusk and overtime it produces multiple layers which can self correct themselves to form a perfect sphere

  3. Stem- Today I researched how flamingos prevent their feathers from fading in the sun. They rub a serum produced from their glands around their tail on their feathers. This serum protects the carotenoids in their feathers from breaking down from the sun’s UV rays.

  4. Stem- I researched about how much of a certain protein someone has can affect how traumatic a head injury could be for somebody. Neurofilament light is a protein detected in blood tests and based how much or little of it you have in your blood, it can affect how severe these injuries are, and how easily you can recover from severe brain injuries.

  5. STEM: For my Science In the News Assignment this week, I researched about pearls. I learned that recently new discoveries have been made regarding their formation. Scientists, using methods of cross-sectioning and spectroscopy, have newly discovered that oysters can control the amount and distribution of nacre in each layer of the pearl. They discovered this by examining the specific layers of a pearl that they had cross-sectioned with a diamond wire.
