Literary Specialist
Just had an exhausting (2 hour) interview for a literary specialist position and I think it really, really well.

- Have students research substances that affect human heart rate
- Obtain blackworms (little aquatic worms translucent enough that a pulse is visible: http://www.carolina.com/product/lumbriculus+variegatus%2C+living%2C+culture.do?keyword=Lumbriculus+variegatus&sortby=bestMatches )
- After observations, have students hypothesize about what can affect pulse rate in blackworms. ID variables.
- Record starting heart rate!
- Perform experiments (make available caffeine, ethanol, assorted other chemicals)
- Record final heart rate!
- ID variables again to reinforce!
- Graph ALL THE THINGS
- Students make scientific presentation to share findings and comment on original hypothesis
- Error analysis, possible future experiments, etc
- The end
Got the idea from one of my teaching fellowship colleagues, and I finally feel at peace re: second week of school. This will be especially perfect for my ecology students and set them up nicely for designing a STEM fair project.

Daphnia are also good for this kind of experiment. I had a group of students research heart rate with Red Bull, Coke, and Gatorade on Daphnia.
