Quality Teach Speech Presentations (E.C. - Berry)

• Use Microsoft PowerPoint (save as 97-2003) or Google slides., or Prezi.com.
• Content should reflect YOUR understanding. Do not copy and paste from the Internet (this is plagiarizing). 
• Keep the design very basic and simple. It shall not distract.
• Pick an easy to read font face.
• Consistently use the same font face and sizes on all slides.
• Keywords only. No sentences!
• Use images to reinforce or complement your message, not to decorate.
• Use images to visualize and explain. Talk about your pictures. Gesture.
• Cite all images below the actual image, whether from Microsoft clip art or a website. 
• No animations or useless graphics. (School computers are slow.)
• Have a title slide, table of contents slide, organized content slides, and a source slide. 
• Practice! Be prepared!
• Know your slides inside out.
• Never read your slides; talk freely.
• Know how to pronounce all words. Dictionary.com will pronounce most words for you.
• Speak with confidence – loud and clear.
• Don’t speak too fast. You are not giving your speech for yourself. You are giving your speech to teach OTHERS what you learned.
• Maintain eye contact with the audience.
• Bibliography (source slide) should include at least three sources. One must be a book.
• Relax! You made an INTERESTING presentations. We will enjoy it and learn from it! :)
• Presentation should be 4-6 minutes long.
• When you're sure you're done, e-mail it to TAG5Berry@gmail.com. The subject should be your first and last name with your topic name. Only use this address for PowerPoints or class projects. Communication should be through the other e-mail address.

Now, what happens if you "force" shapes to tessellate by joining your gaps? Look at these hexagons and pentagons:

By forcing the shapes to not have gaps, the structure takes on a curved shape, resulting in a truncated icosahedron (a.k.a. soccer ball).

This website, named for Archimedes, is fantastic for acquainting yourself with polyhedra. (Notice "poly"? Think word study.)
