2. Water Cycle Experiment
points-1 point each for steps a, b, and c)
Instructions: This experiment is designed to help students
understand how extreme climate
events like drought and flooding will affect plant growth. Classes will prepare at least two
control pots and two pots of each treatment to test the effects ofdifferent watering "treatments"
on corn growth. In pairs orgroupsofthree, complete each ofthe 3 steps below for one or two
control pots or one or two ofthe three listed treatment pots. Your teacher will indicate how
many pots to prepare. After following these steps in your group, check with your teacher
to
receive a stamp for following correct scientific procedure.
a) Fill your 4-inch pots with slightly moistened potting soil to the top of each pot.
b) Using a ruler and a marker, mark 3 cm on the eraser end ofyour pencil. Use your pencil
to push I com seed 3 cm deepinthe middle ofeach pot.
c) Cover the seed with potting soil. Follow the watering directions below for control and
treatment pots. With a pencil, write your and your partner's names, period/mod, and the
water treatment on the label. Place the pot under a light source in the classroom or in the
greenhouse as directed by the teacher.
Control and Treatments:
- Control= Water 3X a week starting at planting ( ml each watering)
Treatment 1 = Water at planting and then water lX a week (100 ml each watering)
- Treatment 2 = Water at planting and then water
lXevery 2 weeks (100 ml each
watering)
- Treatment 3 = Flood with 400 mlofwater at planting, no water for 4 weeks, and
then
flood again ( 400 ml)
3. Hypothesis (3 points)
Remember to use an if/then/because format and make your writing clear. Check
with your
teacher if you need some coaching.
T hink about these questions as you write your hypothe i s:What could you measure on the corn
plants to determine if they have grown or not? How will water or the lack of water affect the
growthofyour com plants? What is changing in the experiment, and what is staying the same?
Which treatment will be the best/worse for plant growth?
