Science 8: pg 151 # 1-9.  Electromagnetic Spectrum placemat.   Lab 5-2 (no questions, just the ray diagrams)

Science 8:  Today we read section 4.2 and did pg 151 # 1-9 in sentences.  We also spent time finishing pg 143 # 1-7 from Monday.  Both of these problems sets are due on Wednesday.


Monday, April 24

Science 8:  Today we spent time finishing these tasks:  Pendulum Lab, WS on waves and frequency, pg 143 # 1-7 in sentences.

Science 8:  Today we wrote our Chemistry Test.  If you were absent, write your test at HW Club on Monday after school.  You will need your usual supplies (ruler, calculator, pencil, and our periodic table).  We worked on the Wave WS and the Pendulum lab today too, but only the WS  is due Monday.

Wednesday, April 19

Science 8:  Today we marked the Practice Test.  We took notes on waves, and how light behave like waves. Frequency is the number of cycles per second for some repeating behaviour, like the wingbeat of a bird.  We calculated that humming bird wing beats occur at about 88 Hz, and students were encouraged to try flapping their arms at that same fantastic rate.  We did a waves WS, which is not due on Friday.  We finished the day with a pendulum lab.

Thursday, April 13

Science 8:  Today we completed notes on Atomic Structure.  We read a section from the Science 9 Text, and did pg 208 (blue hand-out) # 5-10, 12,13 in sentences, which is due Tuesday.  We also did Lab 10-3 from our text, but this is not due Tuesday.  Expect a Chemistry Test at the end of next week.

Tuesday, April 11

Science 8:  Today I collected the Can Implosion Lab and the Density of Irregular Objects Lab.  We looked at some slides showing the TRUIMF particle accelerator in Vancouver.  Please take a free tour if you have time on your next trip to Vancouver.  We created an experiment to prove that condensation on the outside of a cold glass of water does not form by water leaking out of the container.

Science 8:  Due Tuesday is the Density of Irregular objects lab (calculations only, no conclusion) and the Can Implosion Lab (your conclusion will describe how to light and use a bunsen burner, including safety considerations).  The Quark mini-poster is not due.  Please refresh your paper supply.

Science 8:  Today we marked the Atom Drawings you made on Thursday.  We looked at evidence for the existence of electrons.  We watched a video about quarks and then we spent some time researching quarks for a mini poster, which is due on Tuesday.  We finished with a fun quiz on Atomic structure and drawing models.  Due today was the Electrostatics lab, which was not collected.

Science 8:  We started by reviewing Atomic models and practicing sketching 6 different atoms with their internal structure (electrons, protons, and neutrons).  This homemade WS is due Friday.  We then worked on the electrostatics lab, by performing our experiment,  recording data, and writing a conclusion.  This is also due on Friday.

In the second half, we did the Can Implosion Lab, a good excuse to use and learn about bunsen burners.  For a conclusion for this lab, write a how-to manual on bunsen burners.  Include safety precautions, how to start and use it, and mention that it should be cool before returning it to the storage drawer.

Term ends on April 20.  A print out of grades was sent home today and students are asked to show it their adult.  Adults are encourage to email me if they have not seen the print-out andwould like to see it.  (ggale@sd19.bc.ca).

Science 8:  Today we wrote notes on Atomic Theory (atoms are made of electrons, protons and neutrons).   We spent some time exploring static electrical charge, which has role in the structure and behaviour of atoms.  We charged various types of plastic, glass and metals by rubbing them with textiles or fur.  We then held them in a cradle (to allow very small forces to be detected) to determine if attraction or repulsion or no effect occurred.

Science 8:  Today we learned about atoms, then briefly explored the contents of the Periodic Table of the Elements.  We observed about 20 different element samples, and wrote the name, symbol, and physical characteristics in a hand made table with 3 columns.  If you were away, you can look up 20 elements on the web and/or use items around your house to see elements in their elemental forms (diamond or pencil lead(carbon), gold, copper, air (oxygen, nitrogen),  silver, helium, aluminum, zinc, iron).  No homework for Tuesday.

Friday, March 17

Science 8:  Today we made a temperature-time graph for a mystery metal.  From it, we determined the melting points and boiling points.  In a rare moment of poor judgement, the instructor invited students to use their web connected phones to determine the mystery metal's identity.  Lead.  At the end of the day, the Density Lab and Lab 7-4 (Change of State for Water).  No work was assigned for Spring Break.



Wednesday, March 15

Science 8:  Today we created a graph of Temperature vs Time for the Change of State for Water lab and we answered pg 256 "What did you find out?" questions.  We did a short lesson on Density, and read pg 260-264.  We did # 1-6 on pg 263 and # 1-4 on pg 264.
