Chemistry 11:  After the Reactions Unit Practice Test was collected, we did the Reactions Unit Test.  Following this, time was given to work on Lab 20C (all questions & a fine conclusion) as well as Unit 8 # 13-19 and 22.  Both of these tasks are due on Friday.  We looked at the evidence for subatomic particles, including a real Cathode Ray Tube, [shows us electrons] as well as an amimation of Rutherford's Gold Foil Experiment [indicates a small, dense, positive nucleus]  We also looked at some pics of an recreation of Rutherford's actual experimental set up.

Chemistry 11:  Wednesday, tomorrow, we will have a Reactions Unit Test.  Today we wrote notes on Atomic Theory, then we read pg 139 -148.  Lab 20C, with a  Conclusion, is due Friday.  The Practice Test is due Wednesday at the start of class.  Click here to view the Reactions Practice Test answer key.

Science 8:  We reviewed reflection and refraction, then we used some concave mirrors to cast a real, inverted image of Crusty the Clown onto a screen.  With the image in focus, we measured the focal length of the mirror.  We did Lab 5-7, but this is not due Thursday.  Read pages 168 - 175.

Chemistry 11:  Today we worked on the Practice Test and Lab 20C.   Due Tuesday is the Practice Test and Lab 20C (all questions, no conclusion).  We will have a test on the Reactions Unit on Wednesday, May 3rd, 2023.

Science 8:  We went through pg 171 # 1-5, then we learned about refraction.  We watched this clip to try to understand why light refracts when it enters glass or plastic.  We did lab 5-3, and we only recorded the path of the light ray as it entered the block and as it exited the block.  We measured the angle of incidence and angle of refraction at each boundary, for a total of 4 angle measurements.  Angles are always measured agains the normal.
