Oyster Doctors: High School Workshop

Description: What are those slimy, squishy invertebrates? This workshop includes an oyster dissection and introduces students to shellfish, their unique biology, and their challenges to survival in diverse marine environments. Students start by collecting phenotype data and observing oysters for infection by macroparasites. Then, students dissect an oyster collected from the US Atlantic or Gulf coasts and locate such anatomy such as the gills, digestive tract, and gonads! Students will then learn how to measure ocean salinity using a refractometer and discuss how oysters can adapt to rapidly changing marine habitats.

I designed this workshop and have presented it during: 
  • COSA (Coastal and Ocean Science Academy), Northeastern University Marine Science Center 2025
  • Northeastern High School Marine Science Symposium 2024
  • Northeastern High School Marine Science Symposium 2023
  • COSA (Coastal and Ocean Science Academy), Northeastern University Marine Science Center 2023

Northeastern Global News wrote an article about the 2024 Marine Science Symposium and featured the workshop here! Photos from the workshop were also featured here in the 2023 press coverage. 

Workshop Presentation Materials:
All workshop materials are available for public use. The workshop is designed to run for 20-30 students and takes ~ 1 hour to facilitate. 

(1) The presentation for the workshop is available here.
(2) The student participation sheet is available here. 
  • This worksheet is designed to be distributed to each student. Students will fill in their observations for each section, following closely with the powerpoint slides.
(3) A list of materials required for the workshop is available here.

Skype-A-Scientist

I began outreach with the Skype-A-Scientist program in the spring of 2024 to share my research with K-12 students remotely! During these 60-minute visits, I meet with students and describe what a PhD student in marine science does, how I became a scientist, and present a synopsis of my current research. Prior to the visit, I also distribute a resources worksheet to teachers with activities to help their students get excited about the visit (see below). 

I've recently had Skype-A-Scientist visits to: 
  • Beverly Elementary 5th graders (3 classes)
  • Lighthouse Connections Academy 6th, 7th, and 8th graders

Coastal Massachusetts High School Visits

​
​The Northeastern University Marine Science Center often hosts local high school students from the North Shore of Boston and other coastal Massachusetts regions (Lynn, Swampscott, Revere, Marblehead, Nahant, etc). I have presented my research and pathway to becoming a marine scientist as well as taken students on lab tours through the Lotterhos Lab molecular space.

  • COSA Marine Science Academy, August 2023

Animal Science: K-5 Lessons

I served in City Year AmeriCorps at the San Jose/Silicon Valley, CA site from 2020-2021. While there, I primarily taught 4-5th grade STEM lessons. I also developed an 8-lesson curriculum about animal science suitable for K-5 remote enrichment. These lessons are designed to be presented over a 45-minute period and have activities that can be tailored more to specific age groups within K-5. 

The eight lessons include the following topics: Introduction to Animal Systems, Deep Sea, Desert, Arctic and Tundra, Coral Reefs, Natural History Museums and Preservation (featured slides below), Predation, and Conservation.

​All slideshows, videos, and activities are available for public use here.

LAND ACKNOWLEDGEMENT
We acknowledge the territory on which Northeastern University’s Marine Science Center stands, which is the land of the Mattakeeset tribe (1) of the Massachuset Nation (2,5) and which has been inhabited by the Pawtucket (3,5) and Naumkeag (4,5) people. We honor and respect these peoples' past, present, and future, their continuing presence in this region, and the enduring relationships that exist between them and these lands. We strive to be mindful of these relationships, and to integrate them into our research, teaching, decision-making, and actions, while also acknowledging that we still have much to learn.
