1) When was the idea of the atom first introduced?

The idea of the atom was first introduced by Leucippus of Miletus around 450 B.C.. Leucippus and his pupil, Democritus, theorized that all matter was composed of atoms, or bits of matter too small to be seen. The word "atom" comes from a Greek word, "atomos", meaning uncuttable, because Leucippus believed that atoms were the building blocks of all materials and therefore could not be broken down any further.

2) An earthquake that measures 8 on the Richter Scale would be how many times stronger than an earthquake that measures 4 on the same scale?

The Richter Scale is logarithmic, which means that each successive whole number represents a 10-fold increase in power. Thus, an earthquake that measures 8 would be 10,000 times stronger than an earthquake that measures 4.

3) What physicist discovered that a wave's frequency changes when the source and the observer are in motion relative to one another?

Austrian physicist Christian Johann Doppler (1803-1853) discovered that a wave's frequency changes when the source and observer are in motion relative to one another. This is known as the Doppler effect.

4) What is the gestation period of a Hippopotamus?

The gestation period for a hippopotamus is 8 months. The mother will then go off by herself to have the 27-50 kg. baby which may be born either on land or underwater.

5) In what type of matter are atoms most tightly packed?

Atoms are most tightly packed in a solid, and are usually in a regular pattern. Atoms in a liquid are close together, with no regular arrangement. Atoms in a gas are well separated, with no regular arrangement, and move freely at high speeds.

6) In 2004, what was discovered on the island of Flores in Indonesia?

In 2004, on the island of Flores in Indonesia, a team of Australian and Indonesian researchers discovered the remains of a hobbit-sized human, one that stood no more than a meter tall. Remarkable, these researchers determined that this new species of human lived as recently as 13,000 years ago, shattering the long-held belief that Homo sapiens have had the planet to themselves for the past 25,000 years.

7) What planet has the most moons?

Jupiter has at least 67 known moons. The largest four are called Io, Europa, Ganymede, and Callisto.

8) Hurricanes only form over ________?

Hurricanes are like giant engines that use warm, moist air as fuel--which is why they only form over warm ocean waters.

9) Which method of heat transfer best describes a lava lamp?

Convection, the transfer of heat through a liquid by circulation of currents, is very apparent in lava lamps. When the wax is heated it becomes less dense than its surroundings and rises. As the wax travels up through the water it begins to cool, by dissipating heat into its surroundings, and by the time it reaches top it begins to sink again.

10) Where are your taste buds located?

The taste receptors are located around the small structures known as papillae found on the upper surface of the tongue, soft palate, upper esophagus, the cheek and epiglottis.
