LESSON 2: Testing results of fertilizer.
OUTCOME: Students will determine the significance of the use of fertilizer on their plants.
CONDITIONS: This lesson will take place over the period of six weeks.
ACTIVITIES: Teacher and students…

are the same size and condition. These plants are clearly labeled
plant 1 and plant 2.
2. All students will apply once a week a dose of general 5-5-5 fertilizer
to plant #1 only. Plant #2 will receive water only. Plant #2
is being used as a “control” or check plant.
3. Weekly, students will measure and record the condition and size
of each plant.
4. At the end of the six-week testing period students will share with
the class their records, which note the differences of the plants’ growth
habits.
5. If significant, a conclusion, and therefore a generalization shall
be made about the usefulness of fertilizing plants.
MATERIALS: plants, charts, fertilizer, water, rulers.
