Science 9:  Today I collected pg 57 # 1-6 after going through the answer key.  This clip shows meiosis very well.  We read pages 64 - 67 and filled in a placemat comparing sexual and asexual reproduction.  Next day we will have a quiz on male and female reproductive anatomy.

Chemistry 11:  We learned how to find the empirical formula from the percent composition, then we completed Unit 5 # 46 (a,c,e,f,h,k,j).  Lab 4D was the next item, and all of the Questions and Calculations and Follow-up Questions are due Tuesday.  No Conclusion yet.  Lab 4D will be due Wednesday.  

Science 8:  After a short review of density, we did Lab 7-4 and started the graph of Temperature vs Time (called a heating curve).  Time will be given to complete this graph on Tuesday.  

Science 10:  I collected the WS on velocity and kinetic energy at the start.  This clip shows how waste heat is minimized in when items in machinery has to rotate.  We took notes on radioactive decay, then we read pgs 228 and 229.  This animation shows alpha decay, and this one shows beta decay. Due Tuesday is the WS titled Nuclear Decay Reactions.
