Chemistry 11:  Today we did the procedure for Lab 4D.  Nothing is due for Monday, but ensure that Thursdsay's assignment (Unit 5 # 44/45 (any 10 problems) and 42 a-d ) is complete.

Science 10:  We took notes on speed and kinetic energy, then we complete this WS to practice our skills.  The WS is due Monday.   In the last 25 minutes we went through a short intro on Nuclear energy, the energy stored in the nucleus of an atom.  We looked at this animation of radioactivity called alpha decay.  We also reviewed atomic structure, with a particular focus on the contents of the nucleus (protons and neutrons). 

Science 9:  We added a few notes to our Meiosis diagrams, then we reviewed human male and female reproductive anatomy.   We watched this clip on human pregnancy, then we read pgs 52-56 and completed pg 57 # 1-6 in sentences.

Science 8:  We wrote a results and conclusion section for the Density Lab, then the lab was handed in.  We read pages 260 - 263 and completed Activity 7-6 (Dense, Denser, Densest) in sentence format.  This clip is about gold, which is very dense.   In the final minutes, we determined the density of irregular mineral samples (feldspar and galena) using displacement to find the volume.  Special care was taken to record data in a clear way and show clear calculations to find the density.   More time will be given for the irregular objects on Monday.
