Plants

In Science we have started our plant unit.  We planted bean seeds and grass.   Almost all the bean seeds are growing rapidly and the students were amazed at how quickly the grass sprouted.  We will use the grass to demonstrate erosion and how the grass and roots hold the soil.  The bean seed is demonstrating the life cycle of a plant.

Can a seed grow without soil?

After a 4 day long week-end, we had grass!

BEANS!



We have witnessed the seed coat falling off!

The plant pushing its way out!

WOW!  It is growing without soil! Look how much the seed grew too!
