Chemistry 11:  Today we began by looking at pictures of mixtures and pure stuff at the atomic level to better our understanding of the Kinetic Molecular Theory.  We prepared Lab 2D, the completed the whole procedure.  Well done!  Click here to see the data for table 2.  Due next class is the WS titled "Atoms and Molecules".   At the very end I collected Unit 3 # 33-39.  Click here to see the assignment log.   

Tuesday, Sept 12

Chemistry 12:  After a mini review of rates of reaction we read section 1.4 and completed # 17-19.  We prepared Lab 18C for Thursday in the same way we did in Chemistry 11.   Click here to see the key for the mini review WS.

Science 8:  After a short review of cell anatomy and microscope anatomy, we read pgs 22 to 30 in our Science Probe 8.  We spent some time talking about how to read science textbooks.  Mr. Gale read pg 22 to 24 to you and did his best to point out many text feature like bolded words, titles, and subtitles.  Students read pg 25 - 30 silently then completed pg 31 # 1-6 in sentences. Pg 31 is due Thursday.  We finished with a practice quiz on microscope anatomy.

Chemistry 11:  We took notes on the Categories of Matter, then we read section 3.3 and filled in brief notes on Mechanical Mixtures and Solutions.  Unit 3 # 33-39 was competed, and is due on Wednesday.  We finished with a short discussion on separating mixtures - we brainstormed how some mixtures might be separated into their individual components: 

1) contents of a pencil case, a classic mechanical mixture (you would separate the different components mechanically)

2) a mixture of 2 gases (someone suggested cooling it until one gas condenses, then drain off that liquid)

3) a mixture of sand, salt, iron bits, and sawdust (!!)

4) a mixture of two food colorings (what?)
