2. Conduction, Convection, Radiation…Match the photos to the correct heat transfer method

4. What do these results tell us about thermal energy?

5. 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.

9. Energy Conversions

10. 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.

11. Circuit City! Build your own!

12. 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

13. Resistors around the house?

14. 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

15. What type of bulb?

17. Current & Magnetism:How are they related? Observe what Michael Faraday observed!

28. 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

29. 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

36. Bonding: Ionic or Covalent?

37. Organic Molecules Carbo the Carbon Atom It’s all about carbon!

38. The Global Carbon Cycle

39. Monomers, Polymers, & Crosslinking

40. 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. ? =
