Worm Lab
Procedure: In the worm lab, we looked at some tiny nematodes called C. elegans under two levels microscope and observed their behaviors.
Observations:
Low level microscope (3x)
High level microscope (10x)

Worm Lab
Procedure: In the worm lab, we looked at some tiny nematodes called C. elegans under two levels microscope and observed their behaviors.
Observations:
Low level microscope (3x)
- Snake-like
- Big bunches and little individuals
- Transparent
- Tiny
High level microscope (10x)
- Metallic/black in color
- Bigger worms hanging out with babies
- Snake-like
- Bigger looking than the lower power
Research:
- Transparent organism
- They can be male and hermaphrodite (both genders in one organism)
- In nature, hermaphrodites are common
- Self fertilization - approx. 300 eggs
- Male with hermaphrodite - approx. 350 eggs
- Contains constant 959 cells
- Life span = 2-3 weeks
- Used for genetic research
- Life cycle:

Questions:
After the observations in the worm lab, we went outside and collected samples of dirt to see if we could capture nematodes. My group, made up of Evan, Thomas, and me, got these two samples:
- Why is it transparent?
- What human-like organs do they have?
- What do they eat (other than e. coli)?

Observations:
Side 1: Found under a paving stone to the left of the entrance to the High School
Dark dirt, really moist, bigger particles, little rock things in it.
Side 2: Found next to the rock pile in crevasse behind Middle School.
Moss in small, bright green, chunks, light dirt, little salt looking particles (not naturally there).
Findings:
Neither of our dirt samples held nematodes, sadly, though there were a few in our class that did.
