51.  1.2 x 10^-10

Chemistry 12:  We began with a short discussion about the equilibria in a saturated solution, and how the equilibrium reaction equation is traditionally written as a dissolving reaction.  The Keq is called Ksp for dissolving reactions.  We did Review of 3.1 to 3.4, then we did the Solubility Lab WS.

Science 8:  Today I collected the Measuring Volume WS.  We learned how to determine the density material by first finding mass and density.  Everyone found the density of a metal, a non metal solid, water, and a colored liquid. 

Chemistry 11:  Moles Test Tuesday.  I collected and marked the practice test, then handed it back to you.  We took notes on Chemical Reactions then we read pgs 105 - 108, then we did the WS titled "Writing Chemical Reaction Equations", which is due Wednesday.  Moles Unit Test tomorrow - Tuesday.

Science 8:  We did the Immune System Practice Test and the Worksheet titled Measurement.  Click here to see the assignment log.

Science 8:  We went through Elements names and symbols to identify how these are created.  We generated a pretend new element, and created a name and symbol for it (ensuring its symbol was unique).  After a short discussion about solids, liquids, and gases, we looked the the Phet States of Matter animation.  Once we read pgs 246- 249, we completed pg 249 # 1-5.   These are due Wednesday.

Wednesday's Immune System Interactive Link.

 Science 8:  Today I collected the Immune System Flippit and the placemat (Disorders of the Immune System & How to care for your Immune System).  We looked at samples of elements to start our Chemistry Unit.  On a table, we wrote the Symbol, Name, Properties, and Metal/Non Metal category.  In the final minutes we wrote the atomic number as a subscript on the lower left of each atomic symbol.

Chemistry 11:  I collected Lab 4D, which was due today.  We took notes on Molar Concentration, read pgs 96-98, and completed Unit 5 # 59, 61-64 (due Thursday).

 Chemistry 11:  We began with a short review of finding percent composition and finding empirical formula.  Time was given to complete 3 more practice problems (total) from # 44-46, work on Lab 4D, and finish the WS titled "Finding Empirical Formula".  All these items but the WS are due Monday.  Click here to see the assignment log.

Chemistry 12:  Time was spent on Lab 19B, which is due by the end of the day on Thursday.  Click here to see the assignment log.

Science 8: I collected pg 109 # 2,3,5-12, then we reviewed ideas about Vaccines.  We watched this clip about Vaccinations and this clip about mRNA vaccines, a relatively new technology.  We made a placemat to learn about disorders of the immune system and 7 ways to care for your immune system, then we read pgs 112 to 114 to fill in brief notes on the placemat.  The placemat is due Monday.  In the last minutes we marked pg 109 after Neige the Super TA returned our work to us.  Click here to see the assignment log.
