In our Observing Worms activity, you will see how worms are a necessary part of nature's delicate balance.
What You'll Need:
Strong magnifying glass
For this activity, you'll need to find some good-sized worms to observe. You can dig in soft, moist garden soil to find lots of small ones.
To find big nightcrawlers, go out onto a healthy lawn at night with a flashlight. You might try lifting a large stone or flowerpot, or digging under the ground's surface.
Once you've got your worm, wet your fingers and run them down both sides of the worm at once. You may be surprised to feel short, stiff bristles (called "setae") that help the worm move through the soil.
Put the worm on a dry piece of paper and let it crawl. You will hear a faint scratching noise as the setae rub on the paper.
Notice how the worm moves. Strong muscles running up and down the body shorten it, while ring-shaped muscles squeeze it to make it longer.
Write down your findings and make drawings of your worm. Always put the worms back where you found them when you are done. After observing individual worms, watch worms making tracks in our next activity, wiggly workers, on the following page.
