When the frilled lizard of Australia feels threatened, it fans out a hood-like flap of skin on its neck, rears back, and hisses! If that doesn't work, it makes a mad dash for the trees --

which is where it lives most of its life.

Forest in the Clouds

A cloud forest is a rare type of rain forest on a

mountainside. Trees, ferns, and other plants draw

moisture from the clouds that wrap around the slope

-- thanks to a process called horizontal

precipitation. (Precipitation is another word for rain.)


Pit vipers such as rattlesnakes have two pits under their nostrils to detect heat. These pits enable the pit vipers to hunt warm-blooded prey

by sensing electromagnetic energy that is a longer wavelength than visible light. What type of electromagnetic energy do the pits detect?

a) gamma

b) infrared

c) ultraviolet

d) microwave

a) 0%

b) 56%

c) 22%

d) 22%

During clear weather, a bright light can be seen for a long distance. During heavy fog conditions, visibility is greatly reduced and light does not travel very far. Which of the

following best explains the reduced

visibility?

a) light is absorbed by water vapor near the ground

b) light is refracted by water vapor in the air

c) light is reflected by water droplets on the ground

d) light is scattered by water droplets in the air

a)22%

b 33%

c) 23%

d) 22%

Stinky Rocks

A sulfide mineral called arsenopyrite smells like

garlic if you crush or heat it. The sulfur in the rock

reacts with oxygen in the air, creating that familiar

powerful scent. Just don't try to cook with it!

The First Blue Eyes Ever

People with blue eyes all have a single common ancestor. Scientists say

that, less than 10,000 years ago, one genetic

mutation created a "switch" that affected the production of pigment in

some brown eyes, turning them blue.

Swimming Swamp Birds

The hoatzin is a primitive South American bird that

builds its nest over swamp waters. The young have claws on their wings and are great swimmers --

so if their nest is threatened, they just drop

into the water, swim to shore, and climb back

home!
