General Science Vocabulary Trivia Quiz


I was bored so I opened up The American Heritage Dictionary of Science (1986) to a random page for each letter except J (that letter was angering me today). Can you guess the word from its definition?

Quiz Answer Key and Fun Facts
1. A polysaccharide made from seaweed used to culture bacteria and fungi.

Answer: agar

Believe it or not, this word comes to us from the Malay language for jelly. Also, agar is NOT gelatin as is commonly thought! Gelatin is made up of peptides (proteins) and bacteria love to eat it. Agar is virtually indigestible to bacteria and that is what causes them to create colonies.
2. A slow moving or sluggish creek that often runs through marshy ground.

Answer: bayou

This word is from a Cajun version of the Choctaw word for creek, which is bayuk. The term is particularly used in the southern parts of the USA, such as Louisiana and Mississippi.
3. A waxy membrane near the nostrils on the beak of some birds.

Answer: cere

This is from the Latin for wax. Do you want to know how to find out the sex of your budgie? The male has a blue cere and the female has a brown cere.
4. A generator. It normally creates direct current electricity.

Answer: dynamo

This is from the Greek for power. Some engineers distinguish between generators that produce direct current (dynamo) and alternating current (alternator). As an added bonus, Tesla's patent number for his "Dynamo Electric Machine" is 390721.
5. Illness found primarily among certain group of people or plants and found primarily in one region.

Answer: endemic

This is from the Greek for native (in+people). The main difference between endemic and epidemic is that an endemic disease is always present in a population but at a very low percentage. An epidemic is a sudden outbreak of a disease with very high numbers in a group.
6. A unit of frequency equal to 1 trillion Hertz.

Answer: fresnel

There is also an object called a Fresnel lens that is almost without spherical aberration. There is also a Fresnel zone that deals with line-of-sight for electromagnetic waves.
7. Small granular pellets of snow due to riming (adding a thin layer of ice due to condensation then freezing of water vapor.)

Answer: graupel

Graupel looks like miniature snowballs but in actuality, they are small hailstones.
8. What is the unit of inductance when a current varies at 1 ampere/second and creates an EMF of 1 volt?

Answer: henry

Although the unit is named henry after American physicist Joseph Henry, the symbol for inductance is "L" for German physicist Heinrich Lenz. Inductance can either occur on the same circuit (self-inductance) or a nearby circuit (mutual inductance). With self-inductance, the voltage created goes in the opposite direction of the change in current.
9. A number smaller than any positive magnitude yet larger than zero.

Answer: infinitesimal

Despite the apparent self-contradictory definition, many mathematicians believe that infinitesimals exist. The study of infinitesimal and hyperreal numbers is called nonstandard analysis.
10. An exceedingly hot wind from the Sahara Desert that blows into Egypt (usually) in the spring.

Answer: khamsin

The khamsin is very hot (over 100 degrees F) and very dry. It can also create sandstorms and in the past was regarded as a killer.
11. The jagged edge of a petal of a flower that forms a fringe.

Answer: lacinia

LaCinia is also a natural remedy for hair loss (according to their ad) and there is also a Temple of Juno Lacinia on the island of Sicily.
12. A looping turn on a river running along level ground.

Answer: meander

This is one of the ways to tell how old a river is: the older the river, the more meanders it will have.
13. A solution that contains one gram-equivalent of solid for every liter of liquid.

Answer: normal

The term normal can also apply to hydrocarbons where the carbon atoms are in a straight line.
14. A rock that is made up of little spheres of calcium carbonate.

Answer: oolite

The root meaning egg (oo-) refers to the fact that this rock looks like fish roe.
15. The tubes in a vascular plant through which nutrients pass.

Answer: phloem

In woody plants, the phloem surrounds tubes called xylem that carry water. When some trees are cut, you can clearly see the difference between the phloem and xylem.
16. A fifth-degree polynomial.

Answer: quintic

A 1st degree polynomial is called linear, a 2nd degree polynomial is called quadratic, a 3rd degree polynomial is called cubic, a 4th degree polynomial is called quartic or biquadratic, and a 5th degree polynomial is called quintic. There are not special names for polynomials of higher degree.
17. Similar to a root, this plant structure is a creeping underground stem.

Answer: rhizome

A rhizome stores food while a root gathers food for the plant. The best known rhizomes used in cooking are ginger and turmeric.
18. An iron rich black tourmaline.

Answer: schorl

Tourmaline is 7.0 on the Mohs Scale. It is found in more colors than any other mineral. It is also the national gemstone of the United States.
19. The unit of pressure that supports one millimeter of a column of mercury.

Answer: torr

This is also equivalent to 1/760 of one atmosphere or 1333.322368 pascals. The air pressure on the surface of Mars is often given as 6 torrs or less than 1% of Earth's air pressure at sea level.
20. The dark central section of an astronomical body's shadow.

Answer: umbra

A cool picture of what the moon's umbra looks like from space is at http://sepwww.stanford.edu/ftp/Earth_Images/eclipse/
21. The waxy covering of an embryo that protects it from amniotic fluid.

Answer: vernix

Also called vernix caseosa for its visual similarity to cheese. New research indicates that it has antibacterial properties. Another use of the word vernix is Toxicodendron vernix, otherwise known as poison sumac.
22. A diagram that displays various information about the winds at a location.

Answer: wind rose

The wind rose started as the eight points on a ship's compass showing the eight major winds. Today this is called a compass rose and the significance of the winds has been lost.
23. An anatomical object shaped like a sword, like the cartilage at the end of the sternum.

Answer: xiphoid

This word comes from the Greek xiphos meaning a straight sword. The Latin word for sword (ensis) gives the synonym "ensiform".
24. A rare-earth metallic element. Atomic number 70. Melts at 1097 degrees K and boils at 1467 degrees K.

Answer: ytterbium

This element was discovered by de Marignac along with lutetium in 1878 near Ytterby, Sweden. The two elements were separated by Urbain in 1907. Coincidently, these elements were also discovered about the same time by von Welsbach, except that he named them aldebaranium and cassiopeium.
25. A fertilized egg.

Answer: zygote

"Zygote" is a scholarly journal dedicated to gametes and newly developed embryos. Sample articles are "Cysteamine, glutathione and ionomycin treatments improve in vitro fertilization of prepubertal goat oocytes" and "The effects of chemical enucleation combined with whole cell intracytoplasmic injection on panda-rabbit interspecies nuclear transfer".
