12-1C Piecing Together Pangea

Purpose: To find out how the continents fit together before Pangea broke apart.

1. South America and Africa, because they fit nicely. 2. The spots showing where the different animals were because it was self explanatory. 3. a) Yes. b) Knowing at the beginning that some continents flipped over.
 * Analyze**


 * Conclude and Apply

1. a) First I cut the pieces out. Then i pieced them together, which took a bit of time. Then I glued them to a piece of paper. b) I figured out in what areas the fossils were and placed them close together. 2. Because with just one it would have been guesswork. 3. a) Back together again? b) The ecosystems would get dryer because the continent would be closer to the equator.

Purpose: To investigate the rate of conductivity through different metals.

Materials: -four 8cm conduction bars -felt pen -ruler -wax strips or candles -matches -hot plate -brick or block of wood -stopwatch -graph paper -coloured pens or pencil crayons


 * Analyze

1. The wax melted at different times.

2. a) No, some metals conducted better or worse than others.

b) Copper, Tin, Aluminum, Lead, Carbon, Zinc.

**Conclude and Apply

1. As the heat travelled, the molecules started hitting each other, passing it on.

2. Zinc, because it would not warm as fast, therefore transfering less heat to me, therefore hurting me less.

Conduction- the transfer of thermal energy from one substance to another or within a solid by direct contact of particles.
