Science 9:  Today we measured and calculated to determine the density of 4 materials that you chose:  a metallic solid, non-metallic solid, water and a colored liquid.  Organizing your data and calculations as well as showing math statements are essential to making your work readable.  For Tuesday, have all of your calculations completed.

Chemistry 12:  We reviewed the answer keys to this Rates Mini Review #2 WS, then we took notes on Enthalpy.  Time was given to complete U1 # 23-28 as well as Lab 18A.  The entire lab and conclusion is due on Wednesday.

 Science 9:  We practiced 10 names and formulas of ionic compounds, then spent time completing Lab 5A.  Lab 5A is due next class (analysis a-h in sentences).  

Chemistry 12:  We took notes on the recent topics we have covered, the we completed this review assignment.  Time was given for Lab 18A.

 Science 9:  We began with a short review, them we learned how to name and write formulas for binary ionic compounds, like Sodium Fluoride.  We did 10 practice problems, then set up Lab 5A.  In the second half we completed Lab 5A to learn about the chemical change that occurs when a candles is burned.  You will be given time to complete Lab 5A on Friday.  Make sure that pg 208 from Tuesday is complete.

 Chemistry 12:  Mr. Shea collected Unit 1 # 10-17.  Today we Read sections 1.4 and 1.5 to start our learning about Collision Theory.  Please do not test out the principles of collision theory on the ski hill or while driving.  Complete Unit 1 #18-22 in Hebdon as well as the Rates of Reaction Mini Practice WS - both are due Wednesday.   See Monday's post for a link to the WS.  Prepare Lab 18A for Wednesday morning.  Thanks for maintaining your learning while I am away.

Science 9:  Mr. Shea collected pg 192 # 1-12.  We read section 7.1 and completed pg 208 # 2-10, 12, &13, which is due Thursday.  Thanks for maintaining your learning while I am away.

 

Chemistry 12:  Today we read section 1.3 in Hebdon and did # 10-17, which is due Tuesday.  Time was given to complete Lab 7, as well a short WS on Stoichiometry Rate Problems.    To review what we learned today,  recite the  6 Factors that Affect Reaction Rate to the nearest person or empty chair.  On Tuesday, you will Read sections 1.4 and 1.5, and do # 18-22.  You will also do WS titled Rates of Reaction Mini Review. A key will be available later.

Science 9:  Today we finished page 192 # 1-12 (due Tuesday) , and we reviewed classroom safety.  We completed a safety quiz for fun, to test our safety knowledge.    

 Chemistry 12:  Today we went through the classroom safety equipment, then we read sections 1.1 and 1.2.  We completed Exercises 1-9 in quality point form, and this is due Monday.  A little time was given for Lab 7, but this is not due.  We wrote a Quiz in the last 15 minutes.

On Monday we will Read section 1.3 and do # 10 - 17.  We will also finish Lab 7 as well as this WS on Rates Problems using Stoichiometry.  

Science 9:  We marked pg 156 # 2-4 and 7-11, then I collected it from you.  We spent time learning to measure volumes in beakers and Graduated Cylinders - always measure to 1 tenth of the smallest division.  The last minutes were spent beginning pg 192 # 1-12, but this is not due on Monday.  

 Chemistry 12:  Today we started with a lesson on the Rates of Reaction.  The Rates of Reaction WS is due Friday, and we also spent a little time reading section 1.1 in Hebdon.  In the second half we completed Lab 7, but this is not due until Monday.  Please work on getting your supplies, including a calculator and 20 sheets of graph paper. 

 Science 9:  Today I checked your signed outline.  On Friday I will check your supplies.  We learned about how matter is categorized, and we spent time exploring Elements on the Periodic Table.  We watched this clip about Magnesium, which we burned in air to make Magnesium Oxide.  In the second half we read section 5.1 and completed pg 156 # 2-4 and 7-11 in sentences.    This is due on Friday.
