Dorothy Retallack's Experiment

I've looked at some websites about the music on effect of palnt growth, and a few of them contain information about Dorothy Retallack's experiment. So I looked at these websites about her experiment:
http://www.ukpianos.co.uk/plants-respond-to-music.html
http://www.dovesong.com/positive_music/plant_experiments.asp

In her experiment, Retallack placed the same types of plants in 3 different chambers. In each chamber she:
  • put music on for 8 hours non-stop
  • played music on for three hours intermittently (irregular times)
  • played no music

She watched her plants grow and observed that:

  • the plants that was in a room with 8 hours of continuous music died the quickest
  • the pants with the music played for 3 hours grew quickly and healthily
  • the plants with no music on grew not as well as the second one, but better than the first one

She also did some other experiments to extend that experiment. I'm not sure if her results were accurate or reliable. She did publish a book called 'The Sound of Music and Plants' based on her experiment though.

I am going to buy some plants, put them in two different rooms. In one room, the plants will be listening' to a classical music for 3 hours non-stop, because many websites state that classical, soothing music helps plants grow better than hard rock music. In the other room, there will be no music played.

I will allow the plants to grow, and record their appearance and height, etc.

So far, I still dunno which plants to get. I might probably get wattles or weeds.

Graph and thoughts of SRP













Here's my beautiful graph. I hope it's right because it is good to get things right.
If it's not right, then I guess I have to be brighter in the future.

About my SRP, I've been looking for which plants to grow.

I've looked at various websites and most of them say bamboos, but it's clearly not that possible to plant that for some reason. Beans may be possible. I migh go to different shops that specialise in plant anatomy to find out which plants grow the best (meaning the fastest and most distinct, therefore I can tell if it grew better than the others).

Time effficiency is a factor because as many of you (if anyone actually reads my blog) know obediently and frustratingly, we only have 2 months to finish our whole SRP!

So I better find some info on my research project by the time school starts.

Or is that too late?
