A student notices that plants in the desert that are able to grow quickly tend to have a better chance of surviving. After doing some research the student finds out that fertilizers can help a plant grow. Of the different brands the student wonders which of the brands will cause a plant to grow the fastest?

 

A Biological Question - Which type of fertilizer will help a plant grow the fastest: brand  A) Scotts , B) Miracle Grow or C) Pennington?

My Hypothesis: Brand A fertilizer.

Prediction: If Fertilizer A is given to a plant then that plant will grow the fastest when compared to others.

The Experiment:

• Use 4 identical plants.
• Each get the same soil type and sunlight conditions.
• Give water to each plant equally on Fridays.
• Plant 1 will just get water.
• Plant 2 will get water with fertilizer A added (Scotts).
• Plant 3 will get water with fertilizer B added (Miracle Grow).
• Plant 4 will get water with fertilizer C added (Pennington).
• Measure the height of each plant (in centimeters) on Mondays.
• Run the experiment for 9 weeks.
• Graph the data collected to determine which one of the fertilizer brands causes the plants to grow the fastest.
