This kit • Comes with enough chemicals to perform each demonstration five to seven times. • Can be performed in just 10--30 minutes. • Requires only basic labware that you provide. Amaze your students as you produce a large quantity of foam by adding detergent and potassium iodide to hydrogen peroxide.http://www.theopenuniversity.com/post/scholar-catalytic-decomposition-of-hydrogen-peroxide-demonstration.htmlSat, 03 Sep 2011 00:00:51 -0500Available at Ward's Natural Science: wardsci.com The ScholAR Teacher Demonstration is the perfect supplement to your chemistry lectures. This kit • Comes with enough chemicals to perform each demonstration five to seven times. • Can be performed in just 10--30 minutes. • Requires only basic labware that you provide. Create orange-gold foam to generate enthusiasm in your students by adding hydrogen peroxide to a solution of sodium potassium tartrate. As you heat the solution, you add copper sulfate solution to turn the solution to a light blue color. Then, as you continue to heat the solution, it will foam and turn orange.http://www.theopenuniversity.com/post/scholar-orange-and-blue-reversible-redox-demonstration.htmlSat, 03 Sep 2011 00:00:50 -0500Available at Ward's Natural Science: wardsci.com The ScholAR Teacher Demonstration is the perfect supplement to your chemistry lectures.

Gently swirl a flask containing a yellow solution to change the solution to red. If you shake the flask, the solution will turn green. Let the solution sit and it returns to yellow. Includes materials for seven demonstrations.http://www.theopenuniversity.com/post/scholar-traffic-light-reaction-demonstration.htmlSat, 03 Sep 2011 00:00:50 -0500Available at Ward's Natural Science: wardsci.com The ScholAR Teacher Demonstration is the perfect supplement to your chemistry lectures. This kit • Can be performed in just 10--30 minutes. • Requires only basic labware that you provide. This dynamic demonstration illustrates Le Chatelier's Principle and chemical equilibrium. The equilibrium system of iron(III) ion, thiocyanate ion and iron(III) thiocyanate complex ion is disturbed by changing the concentration of reactants. Students observe the equilibrium shifts through the color changes that take place in solution. Placing the reaction vessel on an overhead projector allows the demo to be projected onto a classroom screen. Includes potassium thiocyanate solution, iron(III) nitrate solution, potassium thiocyanate crystals, sodium phosphate, monobasic, instructions, and materials for seven demonstrations.http://www.theopenuniversity.com/post/lechatelier-s-principle-a-dynamic-demonstration-on-the-overhead.htmlSat, 03 Sep 2011 00:00:49 -0500Available at Ward's Natural Science: wardsci.com The ScholAR Teacher Demonstration is the perfect supplement to your chemistry lectures. This kit • Comes with enough chemicals to perform each demonstration five to seven times. • Requires only basic labware that you provide. Nylon is a synthetic polymer that is used in many different products. With this activity, you can show your students how Nylon 610 is synthesized at the interface of two liquids as you wrap it around a stirring rod. The demonstration can be completed in 20 minutes. It comes with the two solutions and instructions.http://www.theopenuniversity.com/post/scholar-nylon-rope-trick-demonstration.htmlSat, 03 Sep 2011 00:00:48 -0500Available at Ward's Natural Science: wardsci.com Expand Student Knowledge of Polymers The ScholAR Teacher Demonstration is the perfect supplement to your chemistry lectures. This kit: • Comes with enough chemicals to perform each demonstration five to seven times. • Can be performed in just 10--30 minutes. • Requires only basic labware that you provide. Ideal for illustrating foam and polymer production, as well as the use of catalysts in reactions, this dramatic demonstration will cause foam to grow 30 times the original volume of the reactants - a polyether polyol and a polyfunctional isocyanate. Use of a hood with adequate ventilation is recommended for this experiment. Materials included for repeat use.http://www.theopenuniversity.com/post/scholar-polyurethane-foam-demonstration.htmlSat, 03 Sep 2011 00:00:46 -0500Available at Ward's Natural Science: wardsci.com A Visual Demonstration of an Exothermic Reaction The ScholAR Teacher Demonstration is the perfect supplement to your chemistry lectures. This kit requires only basic labware that you provide. If the energy released during a chemical reaction is light, it is called chemiluminescence. With this activity you can demonstrate this phenomena to your students right in the classroom. The demonstration can be completed in ten minutes and includes all necessary materials to perform the demonstration five times, as well as instructions.http://www.theopenuniversity.com/post/scholar-chemiluminescence-demonstration.htmlSat, 03 Sep 2011 00:00:46 -0500Watch more free lectures and examples of Organic Chemistry at www.educator.com Other subjects include Geometry, Algebra 1/2, Pre Calculus, Pre Algebra, Calculus, Statistics, Biology, Chemistry, Physics, and Computer Science. -All lectures are broken down by individual topics -No more wasted time -Just search and jump directly to the answerhttp://www.theopenuniversity.com/post/organic-chemistry-stereoisomers-enantiomers.htmlWed, 10 Aug 2011 00:01:42 -0500Please visit www.alokguptaclasses.blogspot.com .

Glenn Seaborg Peter Armbruster Jacob Marinsky Darleane Hoffmann Al Ghiroso -aka "The Mickey Mole Mobile" or even "The Lewis Octet Valence electron Dot Folding and Rolling Periodic Table of the ...."... has been cross country numerous times and signed by over 3000 kids since 1999 (their signatures have faded...) been in the Berekeley Parade six times, Doo Dah Parade. Appeared at over 50 schools to present chemistry lectures to thousands of kids!***** IN NEED OF REPAIR****YOU CAN HELP WITH A DONATION TO FIX SO SHE CAN HIT THE ROAD AGAIN and maybe find a home at a science museum somewhere for a year or so???? (as at the TOWE Museum in SACRAMENTO one year.. Kenneth Gregorich and Sam Markowitz (are the other two Sam just an isotope of tin so a real element discovery) Send or contact ScienceIsGOlden.com thanks GOD BLESShttp://www.theopenuniversity.com/post/periodic-table-car-aka-mickey-mole-mobile-raw-footagetv50-1999.htmlSun, 06 Feb 2011 00:00:56 -0600
