Advanced Science Fair Projects – Expectations for Top Projects and Tips on Getting There – – Statistics –

Teacher Workshops for CUSEF/SLVSEF 2011

The Top Competitions  Intel Science Talent Search • Seniors, individual projects only • New online system • Application DUE November 17th  Siemens Competition • Seniors or teams • Application DUE October 1st

The Top Competitions (cont.)  Junior Science and Humanities Symposium • All high school grade levels • Intermountain region hosted at the U  Other Opportunities • Davidson Fellows • USA Today Academic High School Team • Dr. Bessie F. Lawrence ISSI • Research Science Institute (RSI) • MASTERS & ISWEEP

A Few Basics…  It involves A LOT of hard work and motivation!  Students need mentors  Can use up to 12 months of continuous research

 Maintain a detailed/complete project notebook • eCAT is an electronic lab notebook. An ELN is a valid form of a lab notebook.

Characteristics of ISEF Winners  Winning projects tend to have 3 characteristics: •

Sound methodology



Useful applications and meaningful implications



Contribute something new to science

A Look at the Scientific Method

Environmental Science, 10th ed, by Wright and Boorse

Research and Question  Research will help you find a topic and a meaningful question  College/University libraries  Google scholar  Follow passion, not a “hot topic”

Hypothesis and Methods  Always include the “why”, not just the “what”  Include your statistical hypothesis  Procedures should be similar to that used by science and engineering professionals—ask them!  As many replicates as possible—aim for 30

Analysis and Conclusions  Analysis is the key to sound conclusions  Use statistics to help you analyze your data  State your conclusions (not just “I was right.”)

 Support your conclusions with your analysis  State the “why”—explain the outcome

Presentation and Communication  Communicate clearly, concisely, and correctly  Discuss project and adjacent areas of science  Know the current state of things in your field

 Dress for success  Consult journals/style guides to help with format

Statistics is Your Friend!  Begin with the end in mind  Think stats when: • Developing a hypothesis • Designing an experiment • Analyzing your data • Framing conclusions • Presenting results

Three Principles of Design  Replication • 30 is a great goal  Control • Positive and negative  Randomization • Let chance choose for you (SRS) • e.g. - coin, dice, random number table

Design: An Example  100 bits of granite need to be split into 2 groups  Why randomize? How randomize? • Number for 000 to 099. First 50 random numbers go in control group.

Exploratory Data Analysis  First step in analyzing data – do not skip it!  Start with graphs • Histogram • Boxplot • Scatterplot  Then use numbers • Mean, median, mode, standard deviation
