Science 9:  After a short review of electrical terms we add one more example to our notes on Electrical Energy, then we completed this WS on Electrical Energy.  We watched this clip on Solar energy, and this one on Nuclear energy.  Both ways do not create CO2 emissions directly.  Of the two, only Solar is considered renewable and sustainable.  In the second half we started a review assignment:  Make a crossword puzzle using key terms.  Friday will be practice test day, and Tuesday will be the electricity unit test.

Science 8:  We reviewed terms related to light and the Electromagnetic Spectrum.  I collected Lab 5-2.  We watched this clip showing the principles behind refraction before we completed Lab 5-3.  After reading pages 168 to 174, we completed page 181 # 1,2 and 4 to 9.  #8 was optional.   In the second half we did the star race track challenge, then we used the ray boxes and curved mirrors to learn about foci, focal length, principle axis, converging, and diverging.  Only lab 5-3 and page 181 is due on Friday.
