Group S4 Rebuttal nd (2 Presentation) Joshua Moreno Danielle Miller Scott Marwil General Comments • Overall, there was very little negative feedback on the presentation. • Thanks to all for the constructive criticism. • We feel we have greatly improved our presentation skills from the first presentation to this one. Speaker Performance • Several notes were made about inadequate use of the microphone and laser pointer. We will do our best to ensure that we make full use of the items available to present topics clearly. • We felt that the presentation was a solid performance and that only small improvements could have been made. Presentation • Several comments were made about the good use of relevant pictures and humor. We tried our best to implement more of these aspects into our presentation. • We were missing some citing information and will do our best to not make this mistake in the future. Food • Everyone loves ICE CREAM!!!!!!!!!!!!!! Presentation: Nanotechnology in the Daily Life By Group 4  Fantastic topics chosen  Slides had good format  A lot was presented   ◦ Lots of details and specifics about nanotechnology in computers and cars ◦ Really captured the audience with relevant, and important, data critical to devices used everyday ◦ Easy to read ◦ Lots of helpful graphics ◦ The need for further inquiry of certain topics was almost unnecessary due to thorough presentation Showed a variety of uses from small microprocessors, to travel and clothing, to an overall global economic scale. The topics were broken up into clear, succinct, subjects that were easy to follow, and all important to everyday use.  Group 1 thinks that the only area for improvement would be to practice working together as group presenters more ◦ However, the overall presentation, transitions, data, and topics presented were highly professional  Danielle is a bit quiet when speaking. Perhaps better use of the microphone would have helped S2 review of 2nd S4 Nanotechnology in Daily Life The bad • Sources of images not cited • Some font size was too small • Almost 3 presentations in one file; disjointed feeling • Did they really only use 4 sources for the whole thing? • Not based on any specific paper(s) The good • Professional layout • Color Scheme was effective and not distracting • Relevant figures • Excellent ability to see how electronics and automobile applications are relevant to daily life; not easy to see for clothing By S3: James Kancewick Michael Koetting Bradford Lamb Positives  The variety of topics discussed made the presentation interesting and showed the wide applicability of nanotechnology in common uses.  Speaking was very good throughout the presentation.  Presentation contained plenty of pictures, which helped keep the audience entertained with the presentation. Areas for Improvement  Almost none of the images had cited sources.  Cite your sources!  Although a lot of information was presented on what nanotechnology can do in our daily lives, not much was said about how it achieves these goals.  Add more information regarding mechanisms of each application.  This would have made each application seem more real (i.e. currently being done) and less like the dreams of some futurist. CHEN 481 Presentation 8 Review Group 5 Trevor Seidel Laura Young Pradip Rijal Jason Savatsky Presentation Review • The speakers all did well. They spoke clearly and loudly. • Adding humor to the slides was a good way to keep the attention of the audience. • The topics that they chose to discuss were relevant to the audience. This also helped to make their presentation interesting. • The graphics that were shown complimented the material. Presentation Review • The graphical effects on the car picture with the scratched surface were good and helped to show the scratches to the audience. • Overall, the team did a great job, and the ice cream was very good.  Review: Nanotechnology in the Daily Life S6: Daniel Arnold John Baumhardt Michael Tran Michael Trevathan http://c2.api.ning.com/files/fuwBh-9*s2IPTynyWgo21mY5IfL2QjfDkfW4fFyCspSRbKBDGTafKNslLXXmED5zWcNkoBVWVnn8nkRvyrzKsfAAuEimkf/Daily_Life_by_Ennokni.jpg Review • We enjoyed the macro-scale approach of the presentation; the impact of nanotechnology in our daily lives was interesting • High quality slides ▫ looked like a lot of work was put into making them ▫ Clear and easy to read ▫ Great text to picture ratio • It was a good to split the topic into electronics, automobiles, and clothing. ▫ They all have a large impact on our lives • There were many pictures that helped convey the concepts throughout the presentation that made everything easier to understand Review • All the presenters spoke clearly and confidently ▫ No filler words ▫ Great transitions ▫ Excellent tone/poise/dress code • Improvements ▫ The laser pointer should have been used more ▫ All the pictures and text should have been properly cited (we recognize that each section was sited, but more is required) ▫ The sources at the end of the presentation should not simply be website pages • Overall, great presentation – it was a great change from all the traditional nano-scale experiments • The ice cream made the entire presentation much more enjoyable- thanks!
