a few hives of bees provide an excellent project.

LESSON FOUR. 
SUBJECT : CBOPS. TOPIC : HOW PLAXTS FEED. 
Food from the soil. — The plant food in the soil must be dissolved 
in water before it can be taken up by the roots and used by the plant. 
There are at least 10 elements of plant food taken from the soil, 
but the most important are nitrogen, phosphorus, potash, and 
calcium (lime). 
Food from the air. — Plants take food from the air through tiny 
openings in the underside of the leaf. Carbon is the only element 
of plant food taken from the air. but it unites with water to make 
starch, which constitutes the great bulk of the plant.
