Science 9:  After reviewing Ionic and Covalent Compounds we practiced writing the names and formulas for ionic compounds.  We read pages 156 - 161 and completed Practice Problems #1-3 on Page 161, which is due next class.   We also started a crossword puzzle, but this is not due next class  Click here to see the Science 9 Assignment Log.

Science 8:   We reviewed heating curve graphs to start, then we completed an assignment on Elements - from a hand-out we did page 192 # 1, and 3-9.  In the final minutes we began to learn about the structure of atoms and looked at a Cathode Ray Tube.  Click here to see the Science 8 Assignment Log.  

February 12

Science 9:  We marked pg 223 # 3-8, 10, 11, and 14, then handed it in.  We learned the differences in properties between Ionic Compounds and Covalent Compounds, then we did # 1,2 on a new hand-out of page 234.  This is due next class.   Page 133 # 1-9 is not yet due.   Click here to see the Science 9 Assignment Log.

Science 8:   We completed a second heating curve graph - this one was for a mystery yellow substance.  Following this we reviewed density and prepared our kits for Lab 10-3 for next Tuesday.  In the last part we began learning about Elements and the periodic table.  A number of samples were placed around the side counter and we observed them and recorded their name, symbol, atomic number, and physical properties.    We finished with the beginning of this short clip about Gold.  Click here to see the Science 8 Assignment Log.

Science 8:   We reviewed density calculations, then we finished the Density Lab.  We read pages 260 to 263 and completed activity 7-6.  Only the Density Lab (determine the density of 4 materials, write a nice procedure) is due on Thursday.  We finished with a quiz on the states of matter and phase changes.  Click here to see the Science 8 Assignment Log.  

  Science 9:  We finished Lab 8.1 by completing a fill-in-the-blank Conclusion.  Note the style of writing:  mini essay style, written in third person, the purpose is addressed, etc.  After Lab 8.1 was handed in, we wrote brief notes on Ionic Compounds, then we read pages 140 - 143.  Using a hand-out,  we completed # 3-8, 10, 11, and 14 on our own paper in quality point form, and this is due next day.  Page 133 # 1-9 is not yet due.   Click here to see the Science 9 Assignment Log.

Science 8:   We drew a generic heating curve on the back of our Temperature vs Time graph for Lab 7-4.  We then completed this conclusion and handed Lab 7-4 in.  In the second half we did the Density Lab.  Click here to see the Science 8 Assignment Log.  

 Science 9:  We went through the answer to page 125 and 127 then completed a Density Practice Quiz.   Well do a quiz like this on Monday.  We took brief notes on Electron Arrangement, then read pages 130 - 132.  After Lab 8.1 was completed, we did page 133 # 1-9 in point form (not due Monday).  We finished by going through the answers to Lab 8.1.  Click here to see the Science 9 Assignment Log.

Science 8:  We completed lab 7-4 by finishing procedure #7-10 (drawing a temp vs time graph) and completing the "What did I Find Out" Questions # 1-4 in sentences.  We also practiced measuring volume and mass.   Due Monday is Lab 7-4 (all procedure steps and Questions # 1-4)  Click here to see the Science 8 Assignment Log.  

 Science 9:  Today we learned how to draw Bohr Models for all the elements from #1 to #20.  We read pages 124-127 and we completed #1-2 on page 125 and # 1-2 on page 127.  All these are due on Friday.  We also completed the procedure for Lab 8.1, but this lab is due on Friday.   Click here to see the Science 9 Assignment Log.

Science 8:  We looked over the Mass Mini-Lab first, then we reviewed measurement by completing this review WS.  We then reviewed changes of state and completed the procedure for Lab 7-4.  Only the Measurement WS is due next class.  The Lab is not due Friday.   Lets do a quiz on Friday on changes of state.  Click here to see the Science 8 Assignment Log.  

Science 9:  Today we learned how to draw Bohr Models for all the elements from #1 to #20.  We read pages 124-127 and we completed #1-2 on page 125 and # 1-2 on page 127.  All these are due on Friday.  We also completed the procedure for Lab 8.1, but this lab is not due.   Click here to see the Science 9 Assignment Log.
