Graph – N/A Analyze: <span style="font-size: 12pt; mso-bidi-font-family: Calibri; mso-bidi-theme-font: minor-latin; msobidifontfamily: Calibri; msobidithemefont: minor-latin; msolist: Ignore;">1. I could tell that heat was being conducted along the metal bars because the wax got hot again and melted, some of the metal bars started to melt, as well as getting very hot. <span style="font-size: 12pt; mso-bidi-font-family: Calibri; mso-bidi-theme-font: minor-latin; msobidifontfamily: Calibri; msobidithemefont: minor-latin; msolist: Ignore;">2. A) No, all of the metals conducted heat equally well. B) In best to worse thermal conductor it would be: Copper, Aluminum, Tin, Carbon, Lead, and Zinc.

Conclude and Apply: <span style="font-size: 12pt; mso-bidi-font-family: Calibri; mso-bidi-theme-font: minor-latin; msobidifontfamily: Calibri; msobidithemefont: minor-latin; msolist: Ignore;">1. The kinetic molecular theory helps explain how thermal energy was transferred along the metal bars because the particles on the bars started moving faster and produced more heat from the candle. <span style="font-size: 12pt; mso-bidi-font-family: Calibri; mso-bidi-theme-font: minor-latin; msobidifontfamily: Calibri; msobidithemefont: minor-latin; msolist: Ignore;">2. I would use zinc to stir a hot mixture because it is the worst to conduct heat, so it would not melt or get very hot when stirring the mixture. Conclusion: I learned that all metals have a different rate of conductivity, and some metals will conduct heat better than others and what those metals are.

The albedo in a city would be less than the albedo in a forested area because in a city there are more materials that would absorb the radiation. <span style="font-size: 12pt; mso-bidi-font-family: Calibri; mso-bidi-theme-font: minor-latin; msobidifontfamily: Calibri; msobidithemefont: minor-latin; msolist: Ignore;">B. Concrete. <span style="font-size: 12pt; mso-bidi-font-family: Calibri; mso-bidi-theme-font: minor-latin; msobidifontfamily: Calibri; msobidithemefont: minor-latin; msolist: Ignore;">C. Because concrete absorbs the radiation. <span style="font-size: 12pt; mso-bidi-font-family: Calibri; mso-bidi-theme-font: minor-latin; msobidifontfamily: Calibri; msobidithemefont: minor-latin; msolist: Ignore;">D. Tar. <span style="font-size: 12pt; mso-bidi-font-family: Calibri; mso-bidi-theme-font: minor-latin; msobidifontfamily: Calibri; msobidithemefont: minor-latin; msolist: Ignore;">E. Because the black tar would absorb the most heat and it would take the longest to release it as well. <span style="font-size: 12pt; mso-bidi-font-family: Calibri; mso-bidi-theme-font: minor-latin; msobidifontfamily: Calibri; msobidithemefont: minor-latin; msolist: Ignore;">F. The role in conduction to create an urban heat island is because the easier a material conducts heat and thermal energy means the hotter the material gets and at a faster rate. <span style="font-size: 12pt; mso-bidi-font-family: Calibri; mso-bidi-theme-font: minor-latin; msobidifontfamily: Calibri; msobidithemefont: minor-latin; msolist: Ignore;">G. The role in conduction to create an urban heat island is to increase the transfer of heat within fluids.

December 10, 2009 12-1C Piecing Together Pangaea Analyze: <span style="font-size: 12pt; mso-bidi-font-family: Calibri; mso-bidi-theme-font: minor-latin; msobidifontfamily: Calibri; msobidithemefont: minor-latin; msolist: Ignore;">1. The continents Africa and North America were the easiest to fit together because they had lines that matched up easily. <span style="font-size: 12pt; mso-bidi-font-family: Calibri; mso-bidi-theme-font: minor-latin; msobidifontfamily: Calibri; msobidithemefont: minor-latin; msolist: Ignore;">2. The lines and the help of the legend made the best clues to fit each piece together. <span style="font-size: 12pt; mso-bidi-font-family: Calibri; mso-bidi-theme-font: minor-latin; msobidifontfamily: Calibri; msobidithemefont: minor-latin; msolist: Ignore;">3. a) I found Madagascar difficult to place. b) Evidence that would help me piece it together is if there were more lines on the piece and if it was bigger.

Conclude and Apply: <span style="font-size: 12pt; mso-bidi-font-family: Calibri; mso-bidi-theme-font: minor-latin; msobidifontfamily: Calibri; msobidithemefont: minor-latin; msolist: Ignore;">1. a) The steps I used to piece together Pangaea are, first, look for all the matching information that is on the legend, then look for the matching lines and finally line everything up. b) The methods I took were to see which pieces matched up together and that is how Alfred Wagner discovered the continental drift theory. <span style="font-size: 12pt; mso-bidi-font-family: Calibri; mso-bidi-theme-font: minor-latin; msobidifontfamily: Calibri; msobidithemefont: minor-latin; msolist: Ignore;">2. I used more than one pieces of evidence because with just 1 piece of evidence, the pieces would not fit together properly. <span style="font-size: 12pt; mso-bidi-font-family: Calibri; mso-bidi-theme-font: minor-latin; msobidifontfamily: Calibri; msobidithemefont: minor-latin; msolist: Ignore;">3. a) I believe the continents in 200 years will be opposite to Pangaea, on the other side. b) British Columbia will not have an ecosystem because we won’t be on the coast anymore.
