  1. Colored Fire (Chemistry Concept)

  2. Big Idea: Visitors use fire in order to learn about 5 common elements on the elements

  3. Goals: Visitors will be able to interact with the exhibit and receive a small dose of information about the periodic table. Visitors will be able to at least remember and/or understand one element that was present in the exhibit.

  4. Idea: Periodic Table & Fire “I didn’t know that potassium could turn fire purple.” (Cognitive) “The Periodic Table isn’t as boring as I thought it was!” (Affective)

  5. Outline of Exhibit • Will have numbered pictures to demonstrate steps for exhibit. • Computer generated voice will inform the visitor about which ever element that they have selected. • Information will be short and brief and only include the element’s atomic number, uses etc. (pictures and bullets will also be available.) • After the visitor hears the brief summary for the element, they will be able to see the element combine with fire and see its reaction.

  6. Performance • 1) Visitor will point on earphones and select desired element. • 2)Visitor will listen to a brief summary about the element. • 3) After the summary the visitor will push a button connected to a small machine or dispenser that will dispense a small amount of the element on a plate. • 4) Visitor will press a button that will ignite a small flame. Visitor will see result of their selected chemical and its reaction with the fire.

  7. Advantages: • This is just a modified version of the flame test, which is done in some high schools. Materials and equipment are cheap and easy accessible. • Some elements are very safe (sodium, calcium) and not explosive. Many can be made a t home. • Easy up keep and not much maintenance. • Since exhibit is interactive and mainly pictures, visitors are more likely to remember something from the exhibit. • Compounds are premade so no big mess. • Fire will be big enough to see a reaction but small enough to not be very hazardous. • Fire proof glass is not that expensive. • Vent fans will ensure that no smoke will be contained in exhibit. • Vent fans are cheap.

  8. Disadvantages • Needs air circulation so exhibit is best place near somewhere that is close to the outside (wall). • Young kids may not be able to read yet, so maybe a computer animated voice should be used to pronounce the names of the elements.

  9. Materials List: • Calcium • Potassium • Coppers (I) and (II) • Iron • Fire Proof Glass • Fire Source( either gas or electric lighter) • Vent fans
