Objectives

• To determine the effect of light intensity on the growth and development of green soya plant.

Page 4: The light intensity can affect green soya seeds growth and development

Tools and materialsTools:• Lamp• Aqua glass• Spoon• Written equipment• Analytic scales

Materials:• Green soya seeds• Water• soil

Page 5: The light intensity can affect green soya seeds growth and development

Variables

Independent variables :• The light intensity:

In sunlight/ outside placeIn dark placeIn usual placeIn lamp place

Page 6: The light intensity can affect green soya seeds growth and development

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

Page 7: The light intensity can affect green soya seeds growth and development

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

Page 8: The light intensity can affect green soya seeds growth and development

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 (+++)

KESIMPULANDari 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).
