An executive Building Committee was quickly formed to oversee the design and construction of the exhibition building, comprising Isambard Kingdom BrunelRobert Stephensonrenowned architects Charles Barry and Thomas Leverton Donaldsonthe Duke of Buccleuch and the Earl of Ellesmereand chaired by William Cubitt. By 15 March they were ready to invite submissions, which had to conform to several key specifications: Two designs, both in iron and glass, were singled out for praise—one by Richard Turnerco-designer of the Palm House at Kew, and the other by French architect Hector Horeau  but despite the great number of submissions, the Committee rejected them all. Opponents of the scheme lobbied strenuously against the use of Hyde Park and they were strongly supported by The Times.
Did you know crystals aren't just for decoration? Crystals are everywhere around us from salt to snow. If you need some science fair project inspiration or just want to make fun keepsake crystals, then try out one of these crystal growing projects.
Goodness, why not try them all? It's a simple and fascinating way to learn about crystals and how common such an extraordinary thing is. Rock Candy When you first think of crystals you may think of a fortune teller bending her eyes into reading a glassy future, or maybe you think of overhead chandeliers in glimmering hotels or your friend's favorite jeans with the snazzy back pockets.
Do you ever think of salt? Because salt also known as sodium chloride or halite crystals is a crystal, as is sugar and snow. Sugar Crystals Now, prepare yourself for some science. Crystals are so common because the word crystal refers to any matter that is arranged in an ordered form.
The units that are arranged can be molecules, atoms or ions which are all much too small to see with the naked eye, but whose arrangement gives crystals their characteristic structure.
There are seven categories of crystal structures which are called lattices or space lattices. Salt Crystals Because of their certain structural characteristic, you can actually grow crystals! Well, not grow like you or a flower grows, but better to say build crystals, like you would build something with Legos.
When the molecules of the to-be crystals called solute are bumping around each other in a liquid called solvent they like to stick together. There are other forces in the solution that cause them to pull back apart but once in a while you get two molecules that hang on just long enough to attract another molecule and then another and another until a crystal structure starts to form.
The more solute in the solvent the faster your crystal will come together.
This process of building crystals is called nucleation. There are so many crystals to explore, play with and create. Here are just two types of crystals to whet your appetite, but know there are many many more out there waiting for you to discover them!
Crystal Needles Crystal Needles are a great introduction to crystal growing. You can have some delicate, really cool crystals going within three hours time! Add the ingredients together in your bowl or cup. Stir the solution until all the salt is dissolved. There may be some crystals still at the bottom, but that's ok.
Place the cup or bowl in the refrigerator and let sit for 3 hours. You can carefully scoop the crystals out of your bowl or cup to get a better look at them. The Needle Crystals are Quick and Delicate Sugar Crystals You may know Sugar Crystals by their other name, rock candy, or perhaps by their most common adjective, delicious!
These take a little longer than the Needle Crystals to build, but they are easy enough to do and their taste is well worth the wait!In this science fair project you will make a saturated solution of sugar and water in order to grow your own rock candy sugar crystals.
You will compare the rate of growth between rock candy that is left to nucleate on its own in the solution, and rock candy that starts off with some assistance. Science projects for kids are supposed to be able to give details concepts of science in a simple way and the projects should be easy enough that they could be performed by kids themselves.
Materials or the equipment used should be accessible easily and the experiments should be protected.. Google Science Fair is a global online competition open to individuals or teams from 13 to 18 years old.
Growing crystals on a cardboard tree is pretty cool, but it isn’t a science fair project. You can create a science fair project by identifying a variable, or something that changes, in this experiment. In fact, at the science fair this past year crystal growing projects were the project de jour, and I can understand why, growing a Crystal Garden has ranked pretty high up there on my list of fun science experiments since I myself was a kid!
The Manual The page, full color manual offers an introduction into the fascinating world of crystals. The step-by-step illustrated instructions guide you through 15 experiments with solutions, crystallization, solubility, temperature, and the chemistry of crystal growing.
Baggie Science This activity introduces students to the idea of chemical reactions by having them mix chemicals inside zip-lock baggies. Although this activity was designed for younger students, it can be used as is or modified for high school students.
