Saturday DNA!

Welcome to the Winter 2015 Saturday DNA! programs!

Come to the science scene on Saturdays!
Color Conscious
Cauli-flower Power
Join us for exciting, new Saturday DNA! sessions!

Add some DNA to your day . . .

One session is offered for each Saturday in this newsletter. The January and March sessions are for students ages10 – 13 each with an accompanying chaperone. The February session is for ages 14 to adult with an accompanying chaperone for any participant under 15. All sessions are two hours long: 1:00 – 3:00 p.m. Chaperones fully participate in all program activities.

Sessions are $15.00 per person ($30.00 for a participating student and accompanying chaperone.)

The sessions are held at the Dolan DNA Learning Center at 334 Main Street, Cold Spring Harbor, NY 11724. Click to view directions to the Dolan DNA Learning Center.

Saturday DNA! was developed by our educational and scientific staff to serve children, teens, and adults interested in DNA programs outside of the school setting. We offer a variety of 2-hour laboratory- and computer-based sessions.

The Eyes Have It: Natural Selection and Senses

1:00 PM – 3:00 PM
Ages 10 – 13; chaperone required

Take a look around you…have you ever truly thought about the number of colors you can see? There are a variety of shades of green on one leaf, the same way there are a variety of yellows on a golden retriever. Color blindness, or color vision deficiency, changes the way a person perceives color with normal light. Some types of color blindness can be traced back through generations using family trees. We invite you to learn how sight, color blindness, and natural selection.

In this activity you will:

  • discuss how you see colors and compare descriptions with your classmates;
  • explore the genetics of being colorblind;
  • learn about how coloring and perception can affect natural selection.

1:00 PM – 3:00 PM
Ages 14 – Adult; under 15 years chaperone required

In 1884, Danish Scientist Hans Christian Gram developed an empirical method in bacterial identification commonly known as Gram staining. Gram staining allows scientists to differentiate bacterial species by the properties of the cell wall. After morphology, or physical features, this method is often the first step to determine the identity and pathology of unknown bacteria. Come join us for a closer glimpse at the microscopic world!

In this lab session participants will:

  • mount various bacterial species onto slides and view them husing compound microscopes;
  • explore the mechanisms and procedure of Gram staining;
  • identify unknown bacteria by their unique physical and chemical properties.

Cauliflower Cloning

1:00 PM – 3:00 PM
Ages 10 – 13; chaperone required

Did you know that the part of the cauliflower plant we eat contains stem cells?  Stem cells are undifferentiated, meaning they haven’t yet “decided” what they are going to be.  In the cauliflower, these stem cells may become flowers or leaves.  Scientists can manipulate these cells and use them to grow new cauliflower plants! 

In this lab students will:

  • clone cauliflower plants from small cauliflower florets;
  • explore how stem cells can be used in research;
  • view plant cells with compound microscopes.
