  5. 5. The surface of the sun is roughly 10,000 °F. At the core, temperatures can reach over 25,000,000 °F.

  8. 8. Created by friction, the ignition temperature for a match is around 360°F. Once burning, the initial burst of heat can reach 1100°F.
  9. 9. How do they make different colored fireworks? By using different powdered elements in the shell. Here are just a few of the elements and the colors they produce. aluminum, titanium, magnesium Silver strontium and copper Purple copper and chlorine Blue barium and chlorine Green magnesium, aluminum White incandescence of iron, charcoal Gold calcium chloride and sulfate Orange strontium, lithium Red Chemical Compound Color

  11. 11. Next month in the Science Lab… … MUSIC
  12. 12. Peppers have a chemical called capsaicin - this is what makes them hot. Because of the effect it has, capsaicin can be used to treat arthritis, headaches, and neuropathy. Peppers can also be used as a deterrent against insects, squirrels, and elephants. Of course, there is always pepper spray to fend of an attacker or a bear.

  14. 14. The Inner Core of the earth, made up mostly of iron-nickel alloy and more than 2,000 miles under our feet, is estimated to be just as hot as the surface of the sun – 10,000°F.
  15. 15. Lava, or molten rock, flows from beneath the Earth’s surface and reaches temperatures between 1300 and 2200°F
