Diffusion, Osmosis and Scratch ...

Above, congrats Daniel for drawing the best flower using Scratch (and mathmatical formulas with the golden angle ... 137.5 degrees).

AP Biology - Today we wrapped up our regeneration lab.  We reviewed biochem, cells and cell membrane ... since we won't be back together for a week.  I did a demo using dialysis tubing and we went over our diffusion and osmosis lab for next week.  Students will prepare discussion questions for Chapter 6 (Enzymes and Biochemical pathways) and Chapter 7 (Cellular Respiration).

Selected Topics in Science - Tomorrow we will continue our study of genetics.  Our planarian and Great Plant Growing Contest will end on Friday.  We have some great bean plants growing!

Computer Programming II - We will wrap up our "The Show" problem that uses sound (music and percussion) and motion tomorrow.  We have already had some great programming performances.  Students will be working on user input programming the next few days.  Two hard working programmers below ...


Computer Programming I - We have moved on to problems that use decision statements and they are considerably harder.  We will check programs again early next week.  Most students are working on the Skyscraper Lay the Carpet problem.  All these programs are in Karel.
