Answer:

Explanation:

Hypothesis: Seeds germinated and grown in soda will not grow as well as those grown in water.

Materials:

Seeds

Paper Towels

Water

Dr. Pepper

Plastic Bottle

Ruler

Procedure:

1. 10 seeds will be tested as the variable and 10 seeds will be tested as the control.

2. The seeds will be placed on a paper towel on the bottom of a plastic bottle. A different

plastic bottle will be used for each treatment (control and variable).

3. Each paper towel will be dampened by the liquids (Dr. Pepper and water).

4. The paper towels will be checked daily (except weekends) and moistened as needed.

5. The length of time it takes for each seed to germinate will be recorded (# of days) and a

seed will be considered ungerminated after 1 week of no growth.

6. After the seeds germinate, growth will be determined by measuring the height of the

plant with a ruler.

7. This will be done for the next week.

8. After the data is collected, the mean number of days it takes a seed to germinate will be

recorded for both the variable and the control. This will be displayed in a bar graph, with

the x-axis having two categories (water and Dr. Pepper) and the y-axis being the average

number of days.

9. The median will also be determined and displayed in a table for the average days to

germinate.

10. The average growth for each seedling will be determined and displayed on a similar bar

graph. The median will also be determined for seedling growth.
