Gummy Bears on Fire!

Image
As this was more fun to do then video, we found an old video on YouTube to give a demonstration. This was fun, exciting and awesome to do!! In this experiment, a demonstration of a spontaneous exothermic reaction will take place between a gummy bear and molten potassium chlorate. Once the potassium chlorate has been melted in a test tube, a gummy bear will be dropped to his doom and flames will burst out of the tube as a result. Materials:  1. Safety first! Wear safety glasses  2. Plastic Shield  3. Gummy Bears  4. Potassium Chlorate (About 5-7 grams)  5. Pyrex Test Tube  6. Ring Stand with Clamp  7. Bunsen Burner  8. Matches  9. Tongs  10.Fume Hood or Snorkel Safety:  WARNING! Do not stand near experiment, and always remain on the outside of the fume hood. Viewers must stay behind demonstrators at all times for safety precautions. Those who are sensitive to light should avoid this demonstra...

Briggs-Rauscher Reaction

Image
Having fun as always in my chemistry lab!!This with 15-17 year olds in a workshop INTRODUCTION The Briggs-Rauscher reaction, also known as 'the oscillating clock', is one of the most common demonstrations of a chemical oscillator reaction.  The reaction begins when three colourless solutions are mixed together. The colour of the resulting mixture will oscillate between clear, amber, and deep blue for about 3-5 minutes. The solution ends up as a blue-black mixture. SOLUTIONS Solution A: Add 43 g potassium iodate (KIO 3 ) to ~800 ml distilled water. Stir in 4.5 ml sulfuric acid (H 2 SO 4 ). Continue stirring until the potassium iodate is dissolved. Dilute to 1l. Solution B: Add 15.6 g malonic acid (HOOCCH 2 COOH) and 3.4 g manganese sulfate monohydrate (MnSO 4  . H 2 O) to ~800 ml distilled water. Add 4 g of cornstarch. Stir until dissolved. Dilute to 1l. Solution C: Dilute 400 mL of 30% hydrogen peroxide (H 2 O 2 ) to 1 L. MATERIALS 300...

Explosion boxes

Box example Explosion Boxes If you love pop-ups – those playful, joyful constructions that bring books and cards to life –  then you will enjoy making “ explosion boxes .” These popular 3D paper crafts take pop-ups to a  whole new world. Like pop-ups, “explosion boxes” offer an engaging way to invite students into the world of  math and engineering. They encourage students to explore and work with measurement, parallel  and perpendicular lines, angles, triangles, symmetry, and transformational geometry, all in the  context of engaging students to design and make themselves. Although the deepest learning comes when students design from scratch,  The simple explosion box shown here is designed to enclose a small Valentine’s Day treat, gift, or note.  It can be printed first and then cut, or cut without printing from coloured card stock or plain white paper  that students decorate themselves. Box Example ...
