=__10-1B Conduction in Action__= =Purpose : To test the ability of different types of metal to conduct heat.=

**Materials :**

 * ======four 8 cm conduction bars (//steel, brass, copper, aluminum//)======
 * ======felt pen======
 * ======ruler======
 * ======wax strips or candles======
 * ======matches======
 * ======hot plate======
 * ======brick of block of wood======
 * ======stopwatch======
 * ======graph paper======
 * ======coloured pens or pencils crayons======

Procedures : see page 432 Chart: Graph: Analyze b) tin, lead, alluminum, zinc, copper, and carbon

 * 1) We melted candle wax onto the metal strip, and let it cool to become a solid again. Then we put fire under the metal to see how fast the the candle wax would melt. by doing this we were able to see if the metal was heating.
 * 2) a) all metals conducted heat, some took longer then others but they all conducted heat.

Conclude and Apply
 * 1) The thermal energy was transfurred from the fire (candle) to the metal, how do we know this? beacsue the particles from the metal when heated made the particles move faster, which then heated the candle wax and started making the candle wax particles move faster forcing it to melt. Proving that the metals used, are conductors.
 * 2) I would use carbon beacause it takes longer for it to heat up, so i would not burn myself. Also carbon does not "fall apart" when heated like one of the other metals did.

Purpose: figure out how all the continents fit together before Pangaea broke apart. Materials: - photocopy of continents - scissors - 21.5cm X 28cm sheet of paper - Glue Procedures: See page 515 Chart and Pangaea on Separate piece of paper. Analyze: 1. South America, Africa, Madagascar, India, Antarctica, and Australia 2. The pieces with the fossils on it, it made a really easy pattern to follow. 3. a) North America, Greenland, Europe, and Arabic (part of Africa at the time) b) if they had a easier pattern to see, or they had fossils. Conclude and Apply; 1. a) I simply took the largest piece and built around that (Africa). I looked for patterns that matched other patterns and any the shape of the continent.   2.  it would have been more difficult to use just one piece of evidence, with four different types it was easier to construct.   3.  a) I think the continents could collide, combing two or more continents. b) Well it would change everything, because North America was to move our climate would change forcing everything living to adapt to new climate and water references.
