Testing Raphanus Sativus Growth by Changing the Amount of Water They are Given

Written by: Clementine, Martin, and Graham 6H

     Our group's hypothesis is "Different amounts of water affect height of Raphanus Sativus." To test this we put 2 radish seeds in four pots and watered them each different amounts of water (0 ml, 25 ml, 50 ml, and 100 ml). Then each week for 4 weeks we measured how tall the average height of each of the pot's plants were. Our hypothesis was supported. 

                                                                      METHODS

     Materials:

• 4 Dandelion seeds
• 4 Radish seeds
• 1200ml of tap water
• 0.8ml of dirt (Miracle Grow)
• 4 ziploc containers Volume= 660cm
• 1 Pyrex measuring cup
• 1 30cm ruler

Procedure:

1. Gather supplies
2. Put 0.2 liters of dirt into each container
3. Put 2 dandelion seeds in each 2 containers
4. Put 2 radish seeds in each 2 containers
5. Water one dandelion  container with 50ml every wednesday
6. Water one dandelion container with 100ml every wednesday
7. Water one radish container with 50ml every wednesday
8. Water one radish container with 100ml every wednesday
9. Record data
10. Take photographs

     Lessons Learned:

• That 50 ml is the best amount of water for radish seeds.
• You must water your plants for them to grow.
• Watering them too much kills them.
