How does a seed grow? 

The goat on the wobbly bridge asked “How does a seed grow?” We investigated using cress seeds. We followed these instructions: 

How to grow cress: 

1. Put cotton wool in a tray. 

2. Sprinkle the cotton wool with water. 

3. Scatter the seeds on top. 

   
      We observed what happened next:

After one day.

After three days.
We came up with this description of how a seed grows: “First the seed swells. Then roots and shoots appear. Next, the stalks get taller and light green leaves begin to sprout. Finally, the leaves expand and turn dark green.”
As cress is a leaf vegetable, we were able to eat it once it was fully grown. We made cress sandwiches. They were spicy and delicious!
