Chemistry 11:  We found the percent error in our water density from the Density Lab, then this was handed in.  Next was Lab 3A, where we completed the procedure, Questions 1,4, and Follow-up Questions 2,3.  No conclusion.  This is due Friday.  Click here for 3A data that you can use if you are away and want to complete 3A now.  We also learned what hydrates are, read page 72, and completed Unit 4 # 6 and 7.  This is also due on Friday.  We finished with a quiz on significant figures and calculations.  Click here to see the Chemistry 11 Assignment Log.

Chemistry 11:  After a practice quiz on Significant Figures and Calculations, we completed the Density Lab.  Everyone had to find the density of 4 materials (a metal solid, a non-metal solid, distilled water, and a colored mystery liquid).  The marked practice quizzes were given back before the end of class, and next day we will do a similar quiz.  The Density Lab is due Wednesday.  Click here to see the Chemistry 11 Assignment Log.

Science 8:  We went over the answers to page 21 # 1-5, then we performed a short inquiry.  "Does diffusion occur faster in hot water, or cold water?" was the question, and everyone worked with an assigned partner to design an experiment, carry it out, and record data and observations.  We finished by listing the single independent variable (the condition that the scientist changes - temperature in this case) and all the controlled factors (every other aspect must be the same for each trial, to be fair).   In the process we learned our way around room 313, practiced being safe and focused, and worked on our science communication skills.  The lab was handed in at the end of class.
