BI 441/541 Human Heredity: Datablitz

One slide, one minute

That's not a lot of time or space! Plan out what you want to say and the best and shortest way to say it.

  • Figure out your points before you make your slide. Talking about something for one minute is easy. Give it a shot once or twice before you make your slide (practice with a timer) it will help you sort out what you want to say.
  • Practice.  You have time. If you want, you can practice 60 times in an hour! This will be less time than most television commercials – you can make great points in a short time... if you refine your thoughts. The entire Gettysburg address takes about 2 and a half minutes, while the sermon on the mount can be read in about 5 minutes.
  • Practice recovering. Don't let a speaking stumble throw you off. You will make mistakes when you practice. They'll help you "go with it" when it happens in front of class.
  • Keep your fonts large and graphics simple. Assume people don’t see well. Even if they do, they will be trying to listen to you. The more you try to cram text on the screen at the same time, the less likely any of it will be understood. Same goes for complex diagrams – there just isn’t time. Simple images work best.

Round 1

Find information on a human disease of your choice that is caused by abnormal genetics.

  • Choose a disease with one main gene involved.
  • Read through several descriptions before choosing a disease. Sign up on the sheet in class. Every student is responsible for choosing one disease upon which to blitz.
  • No more than two students may choose the same disease, so have a back-up choice or two.
  • You will need to find additional resources - at least one reference in addition to the Genes and Disease website is required.
  • Include:
    • name of disease
    • phenotypes
    • chromosome location
    • name of gene affected
    • what the gene product does normall
    • the specific problem with the gene that leads to disease.

Round 2

Choose a “hot topic” (from the list below).

Do some research on your topic using GOOD sources (journal articles, websites sponsored by medical schools/clinics, popular science magazines) and put together a Datablitz II slide. You need AT LEAST two resources, one of which must be a primary journal article (i.e. – the authors of the article describe research they themselves performed).

Include on Your Slide:

  • Your topic
  • basics on what is currently known (from research and good sources)
  • reasons why topic is “cool” / of interest to us.
