Weather...

For my experiment, I should consider the weather. Of course, I should grow the plants on a sunny day rather than on a rainy day, because sunlight can make plants grow better than the rain. So I'll do that. I'll grow them when it's fine and sunny weather, about 20-30 degrees Celsius, maybe a little cooler since it's going to be nearly winter.

Let the music play!

Does music have an effect on plant growth?
So I have looked at a few websites as to the information about my research project, and I’ve found out that:
  • Plants respond to stimuli, that is, they react to something that causes reactions
  • Plants do not respond differently depending on what type of music or artist (e.g. they would not grow faster when listening to Taylor Swift rather than Linkin Park)
  • The relationship between plants and music have something to do with mechanical waves, which are waves that require a medium to travel through (i.e. sound)
  • Therefore plants do not grow faster when music is played because they hear it, but because of vibrations of sound waves
  • Music can affect plants positively or negatively

    So my experiment will be something like this:
    I will grow 3-5 plants normally for a week. The differences with regards to their appearance and height will be recorded. I might repeat these steps for another week to conduct a fair test.
    The following week I will buy the same number and type of plants and grow them. This time, however, the plants will have the music played for them for 2 hours every day for a week (the same song should be played for the entire experiment). The appearance and the growth of the plants will be recorded.
    The process above will be repeated the following week.
    This is just a general idea of how my experimentation would be. I hope it is going to be a great and fun experiment!

    Oh yeah, there are variables that should be considered:

    Independent variables:
  • number of plants
  • type and size of plants
  • period of time the plants will grow

Dependent variables (during experiment):

  • growth of plants
  • appearance of the plants

There should be some more, but so far I can only think of these.

Don't worry, I will think of some more. Eventually.

The winner is

Judging from my previous entries, it seems like I favour 'the effect of music on plant growth'. So, I guess I should do that.
Or something.
I will just choose it and I know it will be a lot of work, but I guess that's the 'beauty' of the project:
The more work you put in, the more you learn and get good marks.
Sure...I'd love that.
Anywho, should add some stuff about music and plants.
Hmmm...I will do that laters.

Bye for now.

So much to choose...so much to lose...

Um...I am kind of in a state where I'm torn between many ideas of my SRP. So...what do I choose?
I seriously have no idea. Actually, I have quite a few ideas, but that's the problem:
WHICH IDEA SHOULD I CHOOSE?

So far, these are my ideas:
  • the effect of music on plant growth
  • do all types of liquid expand when frozen?
  • which substance removes graffiti the fastest or bestest?
  • do plants grow faster in soil or in water?
  • more ideas will be blocking my train of thought and relief

So you see, I'm really trying to choose an idea. I'd like to inny-minny-miney-mo, but I can't. That's just too risky and childish, anyways.

Please let me choose something by, like, tomorrow!

Ideas...

I've been thinking of some ideas for my SRP, I don't know what to choose...

1. What effect does music have on plants? e.g. do plants grow faster with classical, rock or country music on?
2. Will you learn better after doing physical activity or after you rest?
3. How much water does orange contain?

I have no idea what to choose, I seem to be changing my mind constantly but oh well, doing SRP is not meant to be straightforward, is it?
