"The Story of the Seed" Lab Report

Title Page: This is the lab that we performed on growing collard greens with different liquids by Nathan Ferrari, Elliot Hooper, Jack McCarthy, and Ethan Short on 8/22 - 9/14.

Introduction: We are testing which liquid, water, sparkling water, and ginger ale, will make the collard greens germinate the best.  Our hypothesis is, if the Co2 and added ingredients affect the germination of the plants, then the water will germinate the best, followed by sparkling water, and ginger ale won’t germinate at all.We are trying to see if the Co2 in the sparkling water and ginger ale will affect the plant growth.  Also the ginger ale has added flavors and ingredients, so that is another factor.  

Materials: We used a 50 ml watering tool, 3 cups for our plants, 60 seeds(20 each cup), and the 3 liquids, water, sparkling water, and ginger ale.

Method: We put 10 seeds in each cup and water them with 20 mL of each liquid everyday.  1 watered with water, 1 with sparkling water, and 1 with ginger ale.  After we water them, we put them under the lights at the same time.  Then we just repeat everyday for around 22 days.

Results/Analysis: Our results were quite surprising.  Our hypothesis was technically wrong.  We assumed that the ginger ale wouldn’t grow at all and the sparkling water would, but not as good as the water.  What happened was the sparkling water had the most seeds germinated, then water, and then ginger ale.  The ginger ale didn’t grow the best, but still it did germinate.  Next, the water had the tallest plant, followed by sparkling water, and then ginger ale.  We decided to test both of these dependent variables so we could see what did better in which are vs just one area.

Conclusion: In conclusion we discovered that the carbon dioxide didn’t affect the germination of these seeds as much as we thought it would.  However, the added ingredients in the ginger ale did affect the germination as you can see by the graph. We could’ve improved this experiment by having more test like 2 cups of each seeds that were being watered specifically.  Now with what I know I could test different flavors of soda to see which flavors affected the germination the most.
