9. SpongeBob loves to garden and wants to grow lots of pink flowers for his pal
Sandy. He bought a special Flower Power fertilizer to see if will help plants
produce more flowers. He plants two plants of the same size in separate
containers with the same amount of potting soil. He places one plant in a sunny
window and waters it every day with fertilized water. He places the other plant
on a shelf in a closet and waters it with plain water every other day.
