Since Pippy was so quick to end the first Earth Science contest, here is another opportunity for my students in 3rd block. Although, I suspect that this may be a replica of the ancient "white-stone" wall of the Kremlin, it still looks pretty interesting. I did not have an acid bottle with me, but I bet this stuff will fizz! So Earth Science students.... what is it? (Other blog readers......please don't tell!)
Science is everywhere! Of course! I saw many applications of the topics we have been studying in class, recently. As promised, here is your opportunity to try for those bonus points. The first member of the class to post or email me the correct answer is the winner of this one. If you are not in one of these classes, I would love for you to read and comment, but please, contain your enthusiasm and do not give away the answers!
Physics students: This is the famous Czar Cannon on the grounds of the Kremlin. This was built of bronze in 1586 in Moscow’s Cannon Court by Andrei Chokhov.Although it was designed for the Kremlin’s defense, no shot was ever fired from it. If a shot had been fired what would be the shape of the path of the cannon ball, and what would be the approximate components of both the horizontal and vertical velocities?
Chemistry students: The Czar bell (purportedly the world’s largest) was cast at the decree of Empress Anne Ioannovna in 1730. The casters used pieces of an older broken bell made mainly of bronze to make it. During a fire in 1737, cold water was poured over it to extinguish flames and this resulted in a huge cracked piece. Now, look at the close-up. For your contest: What is the green stuff? What are the sources of the two reactants? Give the name and formula of the green product. And classify the reaction type in which it formed in two ways.
Earth Science students: The Armory Museum in the Kremlin has a display of carriages used by the Tzars of Russia. A particular one, owned by Nikita Ivanovich Romanov in the 1640’s has some very nice windows. What is the natural material that was used to make these windows?
Thanks to all of you who are reading and commenting. I am trying to keep up with all of this. So here are a few replies. To Ms. Whiteis.......I think the view from my window includes The Ivan the Great Bell-Tower in the Kremlin and perhaps a bit of The Assumption Cathedral? To Emily and Makayla...... I do not think the cheesy bread will travel well, but I have tasted some awesome candy here, so.....we'll see.Students, Look for the bonus contests very soon!
