Introduction:
Most house plants or home gardens are typically watered with simple tap water or water from a
hose. But, tap water is likely not the ideal water to use when it comes to growing.
Objective:
The purpose of this experiment is to determine which type of water is ideal for germination.
Hypothesis:
If tap water, salt water, and distilled water are used to attempt to germinate batches of seeds, the
batch with tap water will have the most successful germinations.
Materials List:
● Distilled water
● Tap water
● Salt
● Petri dishes
● Graduated cylinder
● 350mL beaker
Procedure:
1. Prepare Petri dishes by lining them with paper towels that have been cut to shape
2. Dampen paper towels with 2mL of water, repeat for each type
3. Place seeds between damp towels
4. Cover with lid and place in light
Data:
Conclusion:
The results of the experiment were inconclusive, as no seeds successfully germinated in any of
the three conditions.
Discussion:
The lack of germination in the seeds is likely due to temperature fluctuation or human error in
setting up the seeds’ conditions.In a repeat of this experiment, temperature would be more
closely controlled and conditions would be reevaluated.
