The golden rain experiment involves two soluble ionic compounds, potassium iodide (KI) and lead(II) nitrate (Pb(NO 3) 2). They are initially dissolved in separate water solutions, which are each colorless.
Elephant toothpaste reaction Two people watching the reaction of Elephant's toothpaste. Elephant's toothpaste is a foamy substance caused by the quick decomposition of hydrogen peroxide (H 2 O 2) using potassium iodide (KI) or yeast and warm water as a catalyst. [1]
So, in early 2001, Ken Hess started a charity with a mission of developing online tools and support for students doing science fair projects. [ 1 ] In collaboration with high tech companies, government labs and agencies (like NOAA and NASA ), universities, and other science education resources, Science Buddies offers scientist-authored tools ...
She teaches general chemistry and scientific literacy to classes of five hundred students. [4] [9] After a few months, she created the program Fun with Chemistry, [10] which introduces elementary, middle and high school students to chemistry experiments. [4] [11] The program reaches more than 20,000 students every year. [4]
The alka-seltzer rocket experiment demonstrates Newton's third law. The film canister rocket has a buildup of gas that wants to come out of the weakest spot making all the gas come out at once through the hole at the bottom. The gas comes out from the underside and pushes the rocket up.
A column of porous black graphite formed during the experiment. Carbon snake experiment. The carbon snake is a demonstration of the dehydration reaction of sugar by concentrated sulfuric acid. With concentrated sulfuric acid, granulated table sugar performs a degradation reaction which changes its form to a black solid-liquid mixture. [1]
For instance, this chemistry is related to the setting of Portland cement, the formation of hydrothermal vents, and during the corrosion of steel surfaces on which insoluble tubes can be formed. The nature of the growth of the insoluble silicate tubes formed within chemical gardens is also useful in understanding classes of related behavior ...
Jeffrey Vinokur was born in 1990 to Russian immigrant parents. He attended Montvale Public Schools. [18] His early interest in science was fueled by doing kitchen science experiments in elementary school, which later progressed to creating a chemistry lab in his parents' garage at age 14, where he would do amateur experiments like making sodium metal from household supplies.
