= **Conduction in Action** =


 * Purpose:** the investigate the rate of conductivity through different metals
 * Procedure:** see page 432 in the textbook
 * Materials:**
 * four 8 cm conduction bars [aluminum,brass,copper,steele]
 * felt pen
 * ruler
 * wax strips
 * matches or candles
 * hot plate
 * brick or block of wood
 * stop watch
 * graph paper
 * coloured pens or pencil crayons
 * **Distance** || **Copper** || **Aluminum** || **Lead** || **Tin** || **Carbon** || **Zinc** ||

 * Analze**

1) I could tell the heat was being conducted because the wax along the strips were melting. 2) a) no they didn't b) tin, copper, aluminum, carbon, lead, and zinc


 * Conclude and apply**

1) The kinetic molecular theory explains how thermal energy was transferred because as the fire was heating the top of the metal bars, the particles were moving faster and faster, bumping into each other as it went down the bar, creating heat 2) I would use tin or copper, because they conducted the heat the fastest up the metal strip


 * Conclusion**

I learned that differ ant metals conduct heat differently, some take longer to heat up with others are more quickly. I also learned that some actually melt and break off.

=**Activity 12-1c**  = = = 
 * Purpose:** to see how the continents fit together before Pangaea broke apart
 * Procedure:** see page 515 in the textbook
 * Materials:** photocopy of continents, scissors, sheet of paper and glue

1) Africa and South America, because there shapes matched each others, and because the patterns where it showed the dinosaur patterns matched. 2) The lines of the dinosaurs and the dotted lines 3)a) I found Greenland hard to place b)If the the pieces was a bit bigger, or the lines going across the piece were bigger
 * Analyze**

1)a) The steps I took to reconstruct it were linking up the patterns of the dinosaur trails, matching up the dotted lines and seeing which pieces have similar shapes where others would fit b)The process was the same because we both used the dinosaur fossils to fit it together 2) I used several pieces of information because without the pieces it would not fit properly or accurately 3)a) I think the Continents could turn into Pangaea, but on the opposite side of the world then the first one, and not as connected b) The ecosystem might become hotter or there wont be one, because if British Columbia moves toward the equator it will become hotter, and if North America joins up with Asia BC might not even have a West Coast
