PRODUCT DESCRIPTION

Make your lesson planning easier with a whole year’s worth of bell ringers for just $39.99! Inspired by “The Disappearing Spoon” by Sam Kean, this file contains 94+ presentations covering hydrogen through plutonium. Take a journey through the periodic table, discovering the uses, etymology, and unusual properties or instances of the element cropping up in history. Excluding multiple variations of presentations (see “Other Information” below, the “Belements” contain 336 slides. Each presentation should take between 2-5 minutes, meaning you’re getting a minimum of 3 hours of material per class. Attention-grabbing and informative!
All presentations (except for Ac, At, and Pa; see below) include:

Slide 1: A picture related to the element.
Slide 2: Physical data (boiling/melting points, density, percent composition of a typical person and the Earth's crust), some more photos, and the etymology of the element's name.
Slide 3: Some chemical properties but mostly common uses of the element.
Slide 4: "Odds and Ends." Trivia, unusual uses, and other stories of how the element has played a role in history. Some presentations have additional slides (e.g., several slides covering iron working and steel are added to Fe).

Other information:
Three elements (Ac, At, Pa) are limited to three slides because of their scarcity and/or extreme radioactivity (i.e., there are no significant uses outside of pure research). Several presentations have multiple copies, denoted by a letter (b or c) after the atomic number. This was done for one of three reasons:
1. Time constraints (removed extra material, e.g., how a turbofan engine works).
2. Some of the material you may not feel comfortable covering, depending on the age/maturity of your class. For example, I removed the spermicidal properties of vanadium for the second presentation.
3. Some of the material may be considered controversial. For example, I cut out most of the information regarding the assassination of Alexander Litvinenko in the presentation on polonium and removed the slides covering the Thiomersal controversy in the mercury presentation.
