Hypothesis Case

Hypothesis:

The roots of the mung bean(s) will grow towards the location of where water is being poured because the plant requires water to survive and generate photosynthesis and the roots transport water and nutrients to the plant so the roots will grow towards the water source.

Apparatus:

1) 9 plastic clear cups

2) Indoor plant soil

3) 9 mung bean seeds

4) Water

5) Ruler

6) Measuring cup in mL

Variables:

Independent Variable: location of where water is being poured into the plant

Dependent Variable: length of root growth

Controlled Variable: amount of water being poured into each plant, amount of soil in each cup, amount of sun light each plant is receiving, temperature, where the seed is being planted

Type of Data:

1) How long the roots have grown each day for each plant

2) If root hairs are visible

3) Color of roots

4) If other roots can be seen branching from main root

5) Direction of roots growing to where water is being poured in

Procedure:

1) Collect 9 plastic clear cups and 9 mung bean seeds

2) Fill up all 9 plastic cups with indoor soil halfway across the cup exactly. All cups should contain the exact amount of soil.

3) Place all mung bean seeds to the left of the cup, in a 2cm depth. Place in where it would be easy to observe root growth.

4) Line up all 9 cups on a table beside each other, in room temperature and allow sunlight to enter the room and make sure the sunlight hits every plant equally.

5) Label all cups 1-9.

6) For the first 3 plants (cups 1-3) pour 10mL of water towards the right side of the cup, opposite side to where the seed is planted.

7) For the next 3 plants (cups 4-6) pour 10mL of water towards the left side of the cup. On top of the seed since that's where the seed is planted.

8) For the last 3 plants (cups 7-9) pour 10mL of water at the center of the cup.

9) Observe daily and water once a day at 8:00pm. Observe and water plant for 7 consecutive days.

Introduction:

Plants require water to survive and to aid with photosynthesis. Photosynthesis is the process of where plants produce their food. Plants contain up to 90% of water. When a plant is properly hydrated, it is tall and sturdy when it is not given the correct amount of water it droops, turns
