Saturday DNA!

Welcome to Saturday DNA! programs!

Come to the science scene on Saturdays!
Join us for exciting, Saturday DNA! sessions!

Add some DNA to your day . . .

One session is offered for each Saturday scheduled monthly during the academic year. Some sessions are for ages 10-13, with a chaperone required, others are for ages 14 to adult, with a chaperone required for participants under age 15.

All sessions are two hours long: 10:00 am – noon. Chaperones register, pay, and fully participate in program activities.

Sessions are $22.00 per person, per session ($44.00 per session for a participating student and accompanying chaperone) plus the Eventbrite registration fee.

The sessions are held at the Dolan DNA Learning Center at 334 Main Street, Cold Spring Harbor, NY 11724. (Directions to this location.)

Please note we use Eventbrite for registration and payment!

  • All seats, in every session, must be reserved using Eventbrite. We do not accept walk-ins.
  • Seats for each session are awarded on a first-come, first served basis.
  • The name and phone number of each ticket purchaser and/or chaperone and the name and age of each minor registrant must be included on your Eventbrite registration. We will not honor reservations that fail to provide this information. If you do not provide this information, your reservation will be cancelled and your registration fee will be refunded.
  • Chaperones must be 18 or older..
  • Once you are registered and payment is made, you will receive an email which will be your entry ticket.

Register through Eventbrite!

The Magic of Microscopes

10:00 AM–noon
Ages 10–13, chaperone required

Our world is full of living diversity. Some of it is visible and much more is too small to see with the naked eye. Join us to explore the visible and tiny, invisible life that surrounds us. Using both compound and stereo microscopes, you will study samples you collect and samples of microscopic life collected by the instructor. What you find may surprise you!

Participants will:

  • collect samples from the local environment;
  • learn how and when to use different types of microscopes;
  • carefully examine samples and record observations.

The Transforming Principle

10:00 AM–noon
Ages 14-adult, chaperone required for students under 15

In 1928, Dr. Frederick Griffith discovered that genetic material can be transferred from one bacterial cell to another, transforming the recipient cell’s traits. He called the genetic material a “transforming principle,” but didn't know what substance caused the change he observed. By the 1940’s, it was established that the genetic material is DNA. Now, scientists routinely use DNA to engineer bacteria and other many other organisms so they acquire many different traits!

Participants will:

  • isolate DNA from a strand of harmless, antibiotic resistant bacteria;
  • introduce the DNA to non-resistant bacteria and determine if transformation occurred;
  • learn about genetic engineering techniques that allow scientists to put other types of DNA into bacteria cells.

December 8, 2018 (Session Closed)


10:00 AM–noon
Ages 10–13, chaperone required

In the 1800’s Gregor Mendel, the “Father of Genetics”, used plants to show how traits were passed from one generation to the next. Mendel’s observed laws of inheritance explain how some genetic diseases and traits are inherited, how children can have different traits from their parents and why some traits can “skip” generations.

Participants will:

  • learn about Gregor Mendel’s classic experiments with pea plants;
  • use Punnett squares to predict outcomes of genetic crosses;
  • build an imaginary creature with unique genetic traits following Mendel’s laws.
