Planaria Lab ends and picts ...

We finished our planaria regeneration labs in both Genetics and Selected Topics today.  We used my USB microscope (thanks Rachel!) for some images before returning our regenerated buddies back to the spring out in Holland. You can see the eyespots developing in the back halves as well as a small head.

These images are after about two weeks, changing the water ever other day and at room temperature.  We have about a 80% success rate, most problems occurred during transfers when changing water.  We also conducted a light and dark test (discussed taxis and kinesis).

In Genetics today we worked on plasmid mapping again and started our discussion questions for Chapter 3.  Tomorrow we will finish these questions and start our paper plasmid lab.

Selected Topics review modes of inheritance and finished the "Find My Baby" problem.  Results tomorrow as we wrap up genetics.  We have an enzyme simulation lab tomorrow ... entitled "Toothpickase".

In computer programming, we are working through our last advance Karel problems ... most students are finished with Karel can Add and are working on the "Lay the Carpet" problem.  We should wrap these problems up by Friday.  That leaves on Mission Impossible!

Faculty meeting after school today ... 3-5.
