COULD YOU EVER MEET AN ALIEN?
a book in the Could You Ever? series by David Darling
Invent your own alien
Describe your alien, how it lives, what it does, and the world it comes
from. Then make a model of it. Begin by imagining a planet going around
another star. Decide on its size, gravitational pull, atmosphere, surface
features, temperature (day and night, winter and summer), length of day
and year, and numbers of moons. How do these factors affect the type of
creature living on its surface? If the gravitational pull is strong, will
the life forms be short and squat? If the planet is completely covered by
ocean, could highly intelligent life evolve? If, like Jupiter and Saturn,
the planet is blanketed by an immensely thick atmosphere, could creatures
develop that looked like flying gas bags?
Be adventurous. Try to come up with something that is totally unlike any
animal or plant you have ever seen before. Describe its body, sense organs,
and lifestyle in detail. How does it communicate? How smart is it? What
has it invented? Can it travel to other planets and stars? Draw or paint
it and its world. Compose a scrapbook about it.
From your artwork, construct a model of the alien. Use stiff wire to obtain
the basic shape. Then cover the wire with strips of paper mâché
until the shape is just right. Use thin wire for antennas, string for hair,
and any other materials you need for special features. Then finish the model
by painting it. Invite friends and relatives to an exhibition of your alien
from Planet X.
