1. Announcements, April 19
• Poster session April 24th, 11am-2pm, Student Commons 2nd
floor, write reviews of three posters (Assign. 4), due April 26
(submit as one word file)
• Assigned research topic (molecule) in the gradebook section
of Blackboard. Assign. 8 is the written report (10 refs, 3 kinds
of refs and 3 databases) and Assign. 9 is the oral presentation,
due April 25.
2. Assignment 8
•
Assignment 8: Complete a literature search on your
assigned molecule, 20 points. Due April 25
• Use at least three searching tools (databases,
including at least two on-line searching tools).
• Locate 10 appropriate references including at least
three different types of sources (journal, book, thesis,
etc.).
• Use American Chemical Society format.
• Summarize each reference using one-two sentences.
•
•
Estimate the importance of the reference to the
research topic (3 = very important to 1= slightly
important).
Upload as a word file into assignment section.
3. Assignment 8 Format
Number each reference 1-10, including the following
information:
a. Authors, Journal information (use ACS format)
b. Title of article
c. Database source (where did you find the article)
d. Summary of article (a few sentences in your own
words)
e. Level of importance (1-3 where 3 is very important
and 1 is not so important to your search)

Title: Time profile of putrescine, cadaverine, indole
and skatole in human saliva.
Database: Google Scholar
Summary: They used concentrations of cadaverine
along with putrescine, indole and skatole to see if
they increased in saliva throughout the day. They
found that vials that contained sodium fluoride
inhibited the formation of cadaverine and putrescine.
They found that cadaverine, putrescine and indole
were most abundant when one first woke up and then
decreased upon eating and brushing teeth, whereas
skatole was not found at all in the samples studied.
Importance: 3
5. Assignment 9

Assignment 9: Give an oral, PowerPoint presentation
on your assigned molecule. 20 points
• Limit your talk to FIVE (5) minutes.
• You should have 3-5 slides describing the topic and
the scientific concepts related to the topic, and 1-2
slides describing your literature search.
• Upload your PowerPoint slides to blackboard by
April 25.
• Grading rubric posted in Assignment 9
• Presentations will be given during class (in various
rooms) April 26. You will receive an email reminder
with your room location next week.
• BRING A COPY OF YOUR PRESENTATION ON

Title
References
Background (not too distracting)
Use color to emphasize
Legible – try to read from back of room
Structures- make sure lines are thick
Limit amount of information on each slide
Do not use large amounts of text
9. Organization of Presentation
• Title and affiliation
• Introduction – state problem
• Background information
– Cartoons helpful
– Include references on bottom of slide
– Restate problem
10. Organization of Presentation
• Results and discussion
–
–
–
–
Data including charts, tables, diagrams, spectra
Label all data clearly
Use limited writing, explain data in detail
May include important experimental details
• Conclusions and future directions
• Acknowledgements
– People who helped but are not coauthors
– Funding sources (NSF REU)
11. Organization of Presentation
• Know your audience!
• Develop talk for audience expected

Professionals
Mixed audience
• Add information or leave out depending on
audience and time frame for presentation
12. Presentation
•
•
•
•
Face audience
Maintain eye contact
Check each slide
Use pointer to emphasize points, avoid
circles with pointer
• Avoid staring at computer or walls
• Project voice and/or use microphone
• Avoid excessive movements

Be enthusiastic
Scientists rarely use notecards
Rehearse in seminar room if possible
Stand back from slides so audience can see
Pace yourself – know time limits of talk
Thank audience for attention
Request questions – do not run away

16. Example 3
• Some backgrounds can be very distracting
• Use of excess color can deter from science
•Excessive amounts of text that goes on and on when
the same point could be made by simply using a few
words that are bulleted is really very ineffective
because the audience will be spending most of the
time reading the work of literature that you have so
carefully written on the slide, instead of paying
attention to the important points you are trying to
make!!
17. Example 4
• Animation can be effective to illustrate
points in a timely fashion
• This keeps slides from being too congested
• Excessive animation can be distracting
• Animation should be kept to a minimum
18. Example 6
Black background makes room very dark
and is harder on the eyes
Choose font size wisely
Times New Roman 28 point
Times New Roman 24 point
Times New Roman 20 point
Times New Roman 18 point
Times New Roman 16 point
Times New Roman 14 point
This 14 point fort will be difficult to read from the back of the room.
