At a greenhouse or garden
store, get some more seeds,
such as radish or bean seeds.
Sprout these as you did the
garden cress. Observe with the
magnifying glass whether they
germinate and whether they
grow faster or slower.
As long as the garden cress seeds are dry, they do not germinate, or start to
grow. Only when they come in contact with water will the seeds swell and begin
to grow. The seeds contain all the important nourishments that the young plants
need for their first growth. The cress will get the rest from the water and the air.
Garden cress is very healthy and contains many vitamins that we need daily. In
addition, the young sprouts taste very good. Therefore, many people plant cress
regularly to eat it in salads.
