Bob loves to garden and wants to grow lots of pink flowers for his girlfriend
Betsy. He bought a special Flower Power fertilizer. He wants to find out if the
fertilizer helps produce more pink flowers. He plants two plants of the same
size in separate containers with the same amount of potting soil. He places
one 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. He would count the number of flowers produced on each
plant. What 2 mistakes did Bob make in his experiment?
