Homework
- Finish Earthworm Lab
- Make isopod lab
- Nature Article
What we did in class
- Earthworm Lab
- Isopod Lab Design
In the earthworm lab, we got an earthworm, placed it on a piece of wet paper towel and observed many things.
We observed the:
- Anterior End
- Posterior End
- Dorsal side
- Ventral Side
- The way it moved
Next we measured the legnth, in centimeters, and the number of segments
The results of each group(length(cm), # of segments):
- 20.5, 175
- 18, 150
- 17, 152
- 16, 164
- 21, 188
Then we looked and felt the clitellum, setae, and seminal receptacles. We then predicted if it sensed light, odor, sound, taste and touch. We did a test to see if they responded to wetness/ dryness and the worm seemed to sense both. A test with ammonia to see if it can smell, and it was able to. Finally we did our own experiment to see if it sensed light.
Tomorrow you are suppose to have a detailed design for the isopod lab.
Hope this post helps out.
Next post is ***Melissa
