Objectives
• To determine the effect of light
intensity on the growth and
development of green soya plant.
Tools and materials
Tools:
• Lamp
• Aqua glass
• Spoon
• Written equipment
• Analytic scales
Materials:
• Green soya seeds
• Water
• soil
Variables
Independent variables :
• The light intensity:
In sunlight/ outside place
In dark place
In usual place
In lamp place
Dependent variables:
• Length of plant
• Length of leaf
• Color of leaf
Control variables:
• Time of watering
• Deep of hole
• Volume of watering
• Total of soil
Relation about physic, chemistry, and
biology
Physic: measure length of stem and
also length of leaf.
Chemistry: the macro and micro
element in the soil
Biology: affect light intensity toward
green soya seeds
Procedure
•

•
•
Choose the best and same green soya seeds
Put it in the water until one day
Prepare 4 of the aqua glass
Give name 1 until 4 to the aqua:
 1 is sun light place
 2 is dark place
 3 is usual place
 4 is the lamp place
• Scale the each soil with 150 gram
• Enter the each soil into aqua glass with have
namely
• Make deep of hole in that soil, the deep is 1 cm
• Enter the green soya seeds into the hole
• Observe the change about green soya seeds
Table of observation result
explanation:
• 1 : sun light
directly
• 2: in dark room
• 3 : usualy room
• 4 : lamp
• yellow (+)
• yellowish green
(++)
• green (+++)

KESIMPULAN
Dari percobaan di atas, dapat disimpulkan bahwa, intensitas cahaya
sangat berpengaruh terhadap pertumbuhan kacang hijau karena
kacang hijau yang mendapatkan cahaya yang cukup (sinar matahari
langsung) panjang batangnya akan lebih pendek, daunnya lebar, daun
berwarna hijau dan pertumbuhannya akan lebih lambat dari pada
kacang hijau yang tidak mendapatkan cahaya. Pada kacang hijau
yang tidak mendapat cahaya (di ruang gelap), pertumbuhannya akan
semakin cepat, panjang batangnya juga semakin panjang, namun
batang tersebut loyo dan batangnya lebih kurus dibandingkan dengan
tanaman yang berada pada tempat yang terkena cahaya matahari
langsung kemudian untuk daunnya yaitu daun tersebut tidak lebar
dan berwarna kuning (pucat).
