General Science For Kids Trivia Quiz

Answer: Jupiter

According to the latest figures (January 2006), Jupiter has an amazing 63 moons! Saturn is second with 47, and Uranus is third with 27. Mars has two moons - Phobos and Demos.

Answer: Hydrogen

The formula for sulphuric acid is H2S04, which means there are 2 hydrogen, 1 sulphur, and 4 oxygen atoms in the sulphuric acid molecule. Sulphuric acid is the acid used in car batteries.

Answer: Light Emitting Diode

An LED is a special type of diode that emits light when a voltage is applied across its little connections. They are used extensively as "pilot lights", and indicator lights, in a whole range of electronic equipment and tools.

Answer: Siamese twins

The name "Siamese twins" is attributed to Chang and Eng Bunker, who lived from 1811 to 1874. Conjoined twins, to give them their more technical name, are born with their bodies physically linked, and have intrigued and amazed people for centuries. There are only a few who have survived unseparated into adulthood.

Some have described their experience, but it must be impossible to imagine what it is like to have such an intimately shared existence, joined to another human being 24 hours a day.

Answer: Does not contain iron

The ONLY property that determines if a metal or alloy is non-ferrous is the fact that it does NOT contain iron. Both ferrous and non-ferrous metals can be magnetic or non-magnetic, some resist corrosion and others don't.

Answer: It would slope up from the ground

When a very long bridge is constructed, it is NOT built perfectly flat. It actually has to have a very slight curve downwards - to account for the curvature of the earth! Theoretically, if an infinitely long bridge was built perfectly level and straight, it would rise up eventually into outer space!

Answer: Lead

Lead melts at 327°C, aluminium melts at 660.25°C. The melting point of copper is a little higher than gold.
Lead has numerous uses in industry; it used to be used for domestic water pipes until it was realised that it is poisonous!

Answer: Cobalt oxide

Blue glass is manufactured by the addition of cobalt oxide. Many different colours of glass can be made by adding different metals and/or oxides. Red glasses are made with gold, copper, or selenium oxides, and one part of nickel oxide in 50,000 produces a tint that may range from yellow to purple, depending on the base glass.

Answer: A space containing absolutely nothing

A perfect vacuum exists ONLY when a space contains absolutely nothing at all. If a space contains so much as ONE atom, it is NOT a perfect vacuum. Even in outer space where there is no air, a total vacuum is not as common as you may think, because even outer space contains dust.

Answer: 28

Our skeletal bones are not totally "set" or ossified until we reach the age of around 28, so until that time we are actually still growing. Scientists are able to tell the age of a skeleton from the amount of ossification in the bones. Most of the cells in our body are replaced when old ones die, so in one sense we never stop growing. Metabolic changes start to occur though at around age 28, and our bodies actually start to "slow down", so unfortunately we start to "grow old".
