Spec Lab, Microscopes and Karel

In Genetics this morning, we had a lab to learn how to use our spectrophotometers.  We had 8 solutions with different amounts of methylene blue.  Students had to put them in order from lowest concentration to highest using the specs.  We started reviewing for our first test which we will continue tomorrow.  Tomorrow's class will be shortened because of homeroom.

In Selected Topics, we finished our microscope lab and our planaria lab ... handing in logs and lab reports.  We looked at onion root tips and counted the number of cells in each phase of mitosis.  We related cell division to cancers and repair/growth.  Tomorrow, we will start review for our first test.  Picts below are from Selected Topics ...

In Computer Science we started checking our first advanced problems and will finish tomorrow.  Next week we have two tough problems ... SkyScraper and Mission Impossible.  After that, it is off to Microsoft qBASIC.

Took a walk to Long Creek and back to Holland after school with Hannah.  Goldenrod, wingstem, jewelweed and ironweed are all blooming.  The first planting of buckwheat is still blooming and the second crop that is mixed with sunflowers and austrian winter peas are about six inches tall.
