Pick up a package of cucumber seeds in your local garden center or store. Share them with your friends and plant them in your back yard or in a container on your balcony or patio, in some good earth. Follow the directions on the back of the package. Be sure to water the seeds regularly and that you place them where the sun shines. Label each row with your names and watch them grow over the summer. When they mature, measure them and see who grew the largest cucumber! Be sure to take pictures so you can see if you can grow bigger ones next year.
