Starting the Garden
Here are the steps you'll need to follow: 

Raking
With a bamboo rake, gather together leaves and trash left from the fall
and winter. Raking is easy, but it needs to be done carefully to be done
right; you may need to practice a bit first. Save the leaves and other
organic debris for your compost heap! 
Weeding
Weeding can be boring, but if you have a big-weed contest, and hang up the
biggest, most unusual, and longest weeds in the hallway display, you'll
have fun challenging yourselves and the work will get done a lot faster.
Small weeds can be pulled by hand, but grass (sod) and large weeds will
need tools, such as a gardening spade. Be sure the weeds come up with
their roots intact. Add the weeds and grass to your compost heap, provided
they haven't been treated with a weed killer. 
Tilling
Now that the surface of the garden is clear, it's time to turn the
soil. This is hard work, particularly with a new patch of ground. The best
way to turn the soil is with a power-driven tiller, although small gardens
can be turned by hand with a spade. Try to borrow a tiller from parents, a
garden center, or a hardware store. You'll need adult volunteers to run
the tiller as well. If more help is needed than parents and staff can
supply, consider putting announcements in the local newspaper, garden
center, or library, inviting the community to a Digging Day. Local
chapters of Future Farmers of America, garden clubs, or agricultural
colleges may also provide help. It's ideal to turn the soil to a depth of
one foot.
