Cool Experiments with Magnets This web site is devoted to magnetism and the cool experiments you can do with permanent magnets and electro-magnets. Some of the experiments are very basic - things you've done since third grade. Others are unique - perhaps you hadn't thought of doing some of these before, or had difficulty in trying to set them up. Lists of the materials needed for the demonstrations, directions on how to assemble them, instructions on how to show them, and notes on how they work are all here for you.
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!7 Amazing Google Science Fair Projects Tonight, Google will announce the winners of its fourth annual Google Science Fair, which Scientific American co-sponsors.
Watch the awards ceremony here live. All Science Fair Projects. feelthefish.com What an awesome list!! I run a Science Club and these would be awesome for class ideas!! Thank you!! Report Kathie.
February 8, We used to do a science fair at our school, but it was more like a parent fair. Most of the projects were completed by parents. Awesome Science Fair Projects. Your Key to a Great Science Fair Project. Airport Manned Just By Robots.
When you think about an airport, you naturally think about the people who work there. The entire process of getting from your cab to your flight has you meeting and interacting with many airport officials.
However in the future, it may be. Technology Science Projects. Check out our awesome list of technology science fair projects for kids.
Find easy ideas from a range of topics that will help you create a first place prize winning science fair . The Science Fair has become a competitive sport and well-coached kids increase their odds of success. This blog is designed to help parents, teachers, and other mentors become better coaches for students wanting to successfully compete in a Science Fair.
You are down to the wire with your kid's science fair project — It needs to get done and it needs to get done quick.
That's we've provided a few great science experiments you can do at home, in.
