I offered my card to the mother, as the young man had his hands quite full, and told them Advanced Biofuels USA had an exhibit table at the EnergyPath conference, they might want to stop by or to check out our web site. I planned to stop by the poster session to see his project. Science Fair students explain their projects to judges and EnergyPath attendees.

Here's how chemistry should be taught: Briggs-Rauscher Reaction [ YouTube Clip ] The Briggs-Rauscher reaction is a well known example of oscillating chemical reactions, also known as chemical clocks because the periodicity can be used to tell time.
What's going on in the beaker is actually quite a complex set of chemical reactions. Here's how to do it: Here's what happen if you drop a Gummy Bear which is mostly sugarto a tube of molten potassium chlorate: Diet Coke and Mentos Mentos in various carbonated liquids.
From left to right: Shimada [Wikipedia] You've all seen this before. But what exactly happens when you drop a Mentos into a solution of Diet Coke? According to Hyneman he's the mustachioed MythBusterit's a process called "nucleation," in which the particular chemistry of the Mentos candy interacts with the chemistry of the carbonated Diet Coke, causing the carbon dioxide gas, or CO2, to suddenly come out of suspension in the liquid and make a break for freedom.
Basically the Mentos start to dissolve, and it's like tripping a switch. It's not what you would call a chain reaction, because that's something else in chemistry terms, but it's a cascade whereon all of a sudden, all of the CO2 that was contained in the liquid is suddenly not as attracted to the liquid as it was before, because of this slight change in the chemistry that occurs.
Elephant Toothpaste [ YouTube Clip ] Yes, even elephants need to maintain good dental hygiene, but what kind of toothpaste do they use?
Here's a favorite chemistry demo called Elephant Toothpaste no, elephants don't actually use this as a toothpaste, silly - it's only called that because it looks like the kind and quantity of toothpaste an elephant would use. This one's easy to do, all you need is dish soap, hydrogen peroxide, and potassium iodide: Grape Plasma What happens if you put a grape and nuke it in a microwave?
You get something very cool Here's the explanation, according to The Plasma Universe: It is relatively easy to generate a plasmoid using a microwave and a medium that will initiate the formation of a plasmoid, this can be caused by the carbon microparticles in the smoke from a naked flame or match, which ignites and moves about as plasmoids, and some biological cells are known to produce plasma under microwave conditions, such as grapes electrons try to move through highly resistive grape-skin, and plasmoids may form This is due to the fact that microwaves, being high frequency electromagnetic radiation in the GHz range, are capable of exciting electrodeless gas discharges in air, similar to the process used in Sulfur lamps.
Obviously you haven't seen alcohol, barium chloride, boron, strontium, calcium, lithium, sodium, copper, and potassium salts set aflame Magnesium in Dry Ice You've probably heard that fire needs oxygen to burn indeed, the principle behind CO2 fire extinguisher is to use the heavier carbon dioxide to displace the oxygen needed by the flame.
But does a fire really need oxygen? It'll burn even when encased in dry ice solid CO2. Ferrofluid Ferrofluida colloidal mixture of nanoscale magnetic particles in a solvent, reacts to magnetic field in an awesomely bizarre way.
Sachiko Kodama uses ferrofluid to create dynamic sculptures called Morpho Towers:8th grade science fair projects for students and teachers. We offer free high school science experiments on every science fair topic, including physics, chemistry, biology, engineering, and even psychology.

Marine biology is a vibrant subject with a large number of concepts that lend themselves to the scientific process. Marine biology science project topics can cover a large amount of information, but they are best summarized into three groups: ocean geography, ocean inhabitants and chemical compositions in .
Food Allergy Science Fair Project. By Multiple Food Allergy Help on March 21, in Blog. Caleb’s 1st Grade Science Fair Project.
Last night Caleb had the school Science Fair. He was very excited to participate in it this year- [we missed it last year]. When he said he wanted to do the science fair, he did not really have any ideas in mind.
In difficult or simple 8th grade science fair projects, the concentration is kept on including scientific methods and experiment designs. Chemistry Projects Take a look at some chemistry projects for 8th graders in this section.
Detailed guides to help high school students compete in advanced science competitions such as the Intel Science and Engineering Fair, ISEF.
