I found this article over at the National Garden Bureau website which suggests some fun plants to grow.

?What?s best for the environment?? is often asked these days. Well, what?s best for the environment is teaching our children respect and concern for nature. One way to start this training early, and have some fun doing it, is a child?s garden. The immediate and long-term benefits of encouraging a child to plant his or her own garden are enormous.
Through school and the media, many youngsters, even preschoolers, are already very aware of nature and ecology. The garden is an excellent place to reinforce what they have heard and learned and a great place to encourage their creativity and self-discipline. They will be exposed to the beauty of Nature, a beauty they will help nurture, and through growing vegetables they may learn a degree of self-sufficiency. A childhood start on understanding and respecting the environment plants the ?seeds? for future responsibilities. We all know it needs to be done, so let?s do it with fun.

Some ?Fun? Plants to Grow
Calceolaria ? called the ??pocketbook? plant, the blooms resemble old-fashioned purses.
Four O-Clocks ? Easy to grow from seed, these colorful flowers don?t open until mid-to late afternoon.
Torenia ? The ?wishbone plant.? Inside the bloom is a small ridge shaped just like a wishbone.
Lunaria ? The ?money plant? forms disc shaped seedpods that can be easily rubbed and polished to resemble a silvery quarter sized coin.
Scallop Squash ? Summer squashes that resemble flying saucers
Impatiens ? ?Bizzy Lizzy? or ?Impatient? plant. The ripe seedpods burst open to scatter seed. Put a fat one in your hand and press lightly for a good tickle when it bursts.
