Anastasia, Otzi, DNALC

Our fifth graders dug deep into the power of forensics and DNA while at the Cold Spring Harbor DNA Learning Center last week. They were asked to name highlights of their visit:

"The Anastasia Romanov case. It was a great example of how to solve mysteries."

The boys explored how DNA sequencing could solve the mystery of Princess Anastasia Romanov and determine whether she survived the Romanov family massacre.


"When we looked at the pollen and found out where he ate his meals.  I enjoyed this lab because it proves how incredible and advanced science is." 

After viewing in person the 3D replica of Otzi the Iceman (Europe's oldest known natural human mummy), the boys conducted a lab that looked at the types of pollen found in Otzi's digestive system to figure out where he was hiking and eating during his last 36 hours of life.




"The fruit flies because I saw cool genetic mutations." 

The boys also conducted labs in which they used special dissecting microscopes to observe genetic mutations on flies, such as having legs for antenna. 


In addition, a scientist from the CSH Laboratory discussed the use of genetics to combat diseases such as cancer. 




What a day of intriguing, revelatory experiences for our boys, who are currently engaged in a DNA unit that we conduct through Saint David's partnership with the DNALC. The partnership provides our boys with access to real-world scientists at the DNALC and their educators, who collaborate with our science teachers for sessions conducted in Saint David's STEAM labs.
