Take an Animal Census
A census is a count of how many people -- or animals -- live within an area. Governments take a census to count how many people live in the country. You can figure out the animal population of a spot near you when you take an animal census.
What You'll Need:
Wooden stakes or sticks
In an open field or wooded area, use four stakes or sticks to mark off a square that is one meter on each side. Then run string around the four sticks to make an actual square.
Take a census of all the animals inside the square. Look carefully to make sure everybody gets counted. Look under rocks. (Be polite and put the rocks back when you're done counting.) Look in any bushes or trees.
Make a record of your census, telling how many of each kind of insect, spider, and other animal you found living there.
