Green Bean Sprouts
Outline
Introduction Objective of study Factors and Levels Experiment Procedures Data Set Description
Introduction
Green beans are mainly grow in China, Thailand, Philippines, Indonesia, Burma, Bangladesh and India, but also in hot and dry regions of southern Europe and the southern USA.
Uses China: dessert (green bean soup) Indonesia: popular dessert snack (es
kacang hijau)
Introduction
Green bean sprouts are germinated by leaving them watered with 4 hours of daytime light and spending the rest of the day in the dark.
Green bean sprouts can be grown under artificial light for 4 hours over the period of a week.
Fluorescent bulbs or incandescent light bulbs would be the best to use for green bean sprouts.
Introduction
Germination of green bean required: Water Temperature Oxygen
However, in our experiment we leave our green beans in the specific location 24 hours .
Objective
To find out the factors that influence the rate of germination
To explore the main effect that influence the rate of germination
To investigate the interaction of the factors
Factors and Levels
Factors :
1. Location (expose under sunlight (outdoor), normal
room (indoor), air condition room)
2. Number of beans (5, 10, 15 beans)
3. pH (<7, 7, >7)
Experiment Procedures
Place cotton
inside the container
Evenly distribute the green
bean s(5, 10, 15 beans)
Watering(Tap water, RO water,
Diluted Lemonade)
Location(under the sunlight,
