Students conducting a density lab
Teacher: Tracy Vassiliev
Graduate Students: Noah and Mark
Together, this group taught an experimental unit on rocketry to supplement the curriculum the students were already working with, a unit focusing on pressure and related forces using rocketry and the book October Sky. This exercise was broken up into two labs that the grad students worked closely with Tracy on to develop.

The first lab had students designing and building their rockets while at the same time, developing hypotheses about what might happen. The second lab involved building chemically fuelled rockets, demonstrating the science behind chemical reactions and related forces.

Teacher: Jesse DePue
Graduate Students: Nick and Melissa
On their initial visits to Jesse's three Grade 8 physical science classes and one 7th grade life science class, they both spent time introducing themselves and how they got into the field of marine science. They then gave brief PowerPoint presentations explaining their current research.

During their later visits, they taught students the concepts of density and ocean acidification using a PowerPoint presentation and a laboratory activity. For the topic of ocean density, Nick and Melissa had students:
  • Compare warm and cold water: students used a divided container with one side housing the warm water plus food coloring and the other, cold water with a different color. They then lifted the barrier and observed what happened.
  • Compare salt water versus fresh: students used the same divided tank with two colored types of water, but this time one was a saline solution and the other was fresh water. They then observed what happened when the barrier was removed.

On the topic of ocean acidification, Nick and Melissa discussed with students what ocean acidification was, asking questions like, "What is pH?" and "What makes something more acidic?" to guide the class towards increased understanding of how things like a changing climate can affect ocean acidification. During the PowerPoint lecture, they conducted a number of pH-related demonstrations and had students follow along by completing an "Acids/Bases: Learning about pH" worksheet that reinforced the idea that varying pH levels can have an impact on ocean ecosystems.

Teacher: Patricia (Tricia) Bernhardt
Graduate Students: Jeff, Mike, and Karen
When visiting Tricia's classrooms, these grad students focused on biological oceanography. Before diving into classroom activities, the grad students began with brief talks about their current research (spiny dogfish and phytoplankton). They were then able to spend the rest of class helping Tricia's students identify phytoplankton samples from the Gulf of Maine as part of a classroom activity.

During follow-up visits, the grad students had Tricia’s class participate in a "Foraging and Adaptation" game, the objective of which was to demonstrate to students how adapations in species are the result of competition and often increase rates of survival.

Teacher: Anne Mourkas
Graduate Students: Ali and Kerstin
 
Students conducting a density lab
In late March 2013, Ali Chase and Kerstin Cullen visited Anne Mourkas's 6th grade classroom to talk about ocean density and conduct a hands-on laboratory activity to help students visualize how density can vary among fresh and saline water. Throughout the activity, they asked students what they thought would happen at each step in the procedure. After going through the lab, Ali and Kerstin talked about their graduate work, showing photos of themselves in the field (Kerstin in the Arctic, Ali in the Gulf of Maine) and relating these photos to current study topics in Anne's classroom.
