Science 9:  We marked part of the Electricity Practice Test, then I collected it to mark the last portion.  Next day we will have a Test on the electricity unit; all learning since April 2nd.  We then reviewed continents and oceans, and shaded the countries we have visited as well as 3 that we wish to travel to.   A short discussion began about the 4 spheres that are used to organize the surface of our planet:  Geosphere, Atmosphere, Hydrosphere, and Biosphere.    Everyone made a graphic that showed three materials found in each sphere, plus ways that spheres are connected.  We read pages 296 to 299, then everyone sketched Figure 4.7 and added captions.  Below the sketch, 4 greenhouse gases were listed (water, carbon dioxide, methane, and nitrous oxide.

Chemistry 11:  We reviewed endothermic and exothermic reactions, and spoke about how the chemical energy in all the fuels we use originally came from the sun.  After a short review of predicting products and balancing, everyone prepared Lab 20C for next day's titration.  A titration was demonstrated for everyone, since this techique has a number of new glassware items that need special care.  We began Unit 7 # 33 - 36, but this is not due Tuesday.  Arrive with your Lab 20C prepared for tomorrow.   Expect a test early next week on Chemical Reactions.

Science 10:  After a short review of the inner solar system, we watched a short clip on the moon, which oddly enough allowed for the first careful study of the sun.  We completed pg 380 # 2-15 in the old textbook, half in point form and half in sentences.  This is due on Tuesday.

Science 8:  After going through the responses for page 186 # 1-6 we used convex and concave lenses to try to cast a real image of the window onto the classroom wall.  Only Convex lenses could cast an image, and these were small, inverted, and real.  We did the Lenses Mini Lab, then we labelled the Human Eye Anatomy diagram and did the crossword puzzle on the back.  No work is due for Tuesday.
