Grow mustard and cress seeds in a pot on the windowsill. Put a sprinkling of the seeds on a layer of damp kitchen tissue. Ready to eat in a week, kids love fast stuff.
Get a clear glas jar, put a layer of sponge inside it, an inch of water in the bottom to be soaked up by the sponge and put a few peas in between the glass and the sponge, they can see the seed germinate and the roots start to form.
Lettuce seeds germinate fairly quickly in a pot, according to type, then when they are about 3"-4" high, you can plant them out in the garden.
Radishes are really quick, some varieties can be pulled and eaten in a month or so.
Spring onions(scallions) germinate fairly quickly in a pot in the warm, also kids like the way they push up through the compost in a loop. Then when the pot is full of roots, you can plant out the hole deal to continue in the garden.
My first experience with seeds was in kindergarten. My teacher gave us each two marigold seeds and we planted them in a styrofoam cup with a hole in the bottom and some potting soil. We each got to put the soil in the cup, poke a hole with our finger, put in our two seeds, and then cover up the hole. Then, we took them over to the sink and gave them a good dose of water. The teacher put them on the window sill with our names on the cups and we got to watch our seeds sprout, grow, and even bloom. It was fantastic! And you considered yourself the real gardener if BOTH of your seeds sprouted. What fun. I miss my childhood:(
