Amount of Water Affects Growth of Dandelion and Raphanus Sativus-Clementine, Graham, Martin 08'-09'

The Amount of Water Affects Growth of Dandelion and Raphanus Sativus Seeds

Written by Clementine, Martin, and Graham

This experiment was based on the hypothesis the amount of water affects height of dandelion and raphanus sativus (radish) seeds.  The prediction in this experiment was if the amount of water affects height of dandelion and raphanus sativus seeds then the height of dandelion and raphanus sativus seeds should change when the amount of water is changed.  The experiment used four containers, one pot was given 50 ml of water per week and had 200 ml of soil in it and 2 dandelion seeds. Another pot was given 50 ml of water per week and had 200 ml of soil in it and 2 raphanus sativus (radish) seeds. Another pot was given 100 ml of water per week and had 200 ml of soil in it and 2 dandelion seeds.  The last pot was given 100 ml of water per week and had 200 ml of soil in it and had 2 raphanus sativus (radish).  The experiment proved the hypothesis.

 

Materials and Methods

Materials List

•    4 dandelion seeds

•    4 raphanus sativus seeds

•    1200 ml of tap water

•    0.8 liters of potting soil

•    4 containers that had a height of 6 cm, a width of 11 cm and 10 cm of depth (volume of 660 cm)

•    1 standard size measuring cup

•    One 30 cm ruler

Methods

1.    Gather supplies.

2.    Put 0.2 liters of dirt into each container.

3.    Put 2 dandelion seeds in 2 containers and label one with 50 ml D and the other with 100 ml D.

4.    Put 2 raphanus sativus seeds in the other 2 containers and label one with 50 ml R and the other with 100 ml R.

5.    Water one of the dandelion pots (the one that says 50 ml D on it) and one of the raphanus sativus pots (the one that says 50 ml R on it) with 50 ml of water every Wednesday and record data.

6.    Water one of the dandelion pots (the one that says 100 ml D on it) and one of the raphanus sativus pots (the one that says 100 ml R on it) with 100 ml of water every Wednesday.

7.    Record data every Wednesday by measuring the plant height.

8.    Take pictures at the end of the experiment.

Results

       Data Table Comparing Amount of Water and Type of Seeds to Amount of Growth (height)

 

 

* D means dandelion seeds and R means radish seeds.

 

Lessons Learned

  • dandelions do not grow well indoors in New York City
  • Raphanus sativus seeds can grow indoors in New York City
  • The amount of water did affect the growth of the dandelion and raphanus sativus seeds
  • More research was needed
  • In some experiments, raphanus sativus seeds can grow as well or better than dandelion seeds
  • More constants could have helped, such as temperature, and amount of light

Ack: Mr. Wilson for making edits and answering our questions.

type of dirt?
what is growth? Is it height, weight, number of leaves?

need a caption to explain what D and R mean in data table

Great Job! I think that you might want to check for run ons. Also check on the instructions how to do your data table, I can't see your results.

Very well presented show. Each booth had its own style, with varying degrees of information Very interesting.

It was great to see how students were engaged and excited when presenting their projects. They all shared giving information on their experiment, which also showed that the project was a group task. Even though all the experiments where similar, it was still interesting to see each because of the way students
presented data differently. Tania Cypriano

From Olivia: I thought that all the projects were very interesting and full of information. They also stood out with all the fun bright colors. Each one was unique in their own ways. Thanks for the knowledge and fun.
