The diagram below shows how molten rock (magma) rises towards the surface of the earth. There, it may cool and harden into crust, or sink and be reheated.
The apparatus shown in Figure 1 is a homemade “Calorimeter” and was built by a team of students to help them calculate the Calorie content of different foods. Students recorded the water’s temperature change over time as a certain mass of food was burned.

Ohm's Law is a formulation of the relationship of voltage, current, and resistance, expressed as V is the Voltage measured in volts I is the Current measured in amperes R is the Resistance measured in Ohms
What type of bulb? Pure tungsten is steel-gray to tin-white and is a hard metal. Tungsten can be cut with a hacksaw when it is very pure (it is brittle and hard to work when impure) This element has an extremely high melting point (3422 °CC) (6192 °F) • Glass bulb • Low pressure inert gas • Tungsten filament* • Contact wire (goes out of stem) • Contact wire (goes into stem) • Support wires • Stem (Glass mount) • Contact wire (goes out of stem) • Cap (Sleeve) • Insulation (Vitrit) • Electrical contact

Environmental Problems Associated with Fossil & Nuclear Fuels
Fir trees (seen here) and red spruce are particularly vulnerable http://www.scienceclarified.com/everyday/Real-Life-Earth-Science-Vol-3/Biogeochemical-Cycles.html
60% of salamanders that develop in water with a pH less than 6 will die. • Of those that survive, many are malformed with curved spines, stunted gills, etc. http://www.elmhurst.edu/~chm/vchembook/195lakeeffects.html
A limestone monument in Leominster, Massachusetts that has been seriously eroded over the past hundred or so years. Can you identify the animal that rests atop this marker? http://edutel.musenet.org:8042/gravenet/grave_weathering.html

Cross linking may increase the strength of a polymer. Cross linking is a type of bonding that occurs between two chains of polymer. As the amount of cross linking increases, the polymer become less flexible. Often, an agent is needed to promote cross linking. ? =
