LOL...the diagram looks like it was taken out of my college bio textbook...I went to school In Iran and I really don't know how you guys do biology in 3rd grade u.s but anyways...I remeber they told us to put paper towls around a cup and then fill 1/4 of cup up with water. the water has a tendency to pull it self up, in other words it's adhisive, specially when there's a suface to grab from...like triachiams (as best as I can remember, too much drinking not enough studying...) in wood...(paper is taken from wood) anyways, continuing on... the water climbes up the paper towl and moistens it...not too much but just right....leave the cup somewhere dark to simulate a seed being underground (thus no light) and after couple of days it will germinate....
