Okay, so FINALLY thanks to help of friends, family and my athletics coach, Ive come to a decision on my experiment. I have chosen to follow my idea of seed germination + plant growth when plants are watered with different substances. Here's how I'm going to do it:
I'm going to control the germination of 4 seeds (most likely pea seeds), planting them all in foam cups in the same soil. They will then all be placed in a mini green house, that of which I'm planning to make with some help from my dad. I will then water each of the seeds with different substances. i.e. one with filtered water, one with tap water, one with salt water and one with water containing blue dye. I will monitor the growth of each of the seeds, seeing which substance if most effective when it comes to the speed of growth.
I want to run the experiment for around 2 weeks, so it gives the plants time to grow enough for me to see a difference. I will photograph the different stages of the growth every 3 days.
Independent Variable: The type of water i use
Dependant Variable: The growth of the plant.
Controlled Variables: The type of seed i use, the soil i use, the conditions which the seeds are put under.
ok, so thats basically it. I really like my idea as it wont take me too long, but i will discover something useful!!
thanks everyone for all your help! and thanks for following!

Don't just photograph it- you need to make sure that you are actually MEASURING the growth too...
ReplyDeleteThe biggest issue I have with yours is that you have too many variables. The "type of water" is an issue, because what do you mean by TYPE... how do you know if it's the salt affecting the plant, or if it's the dye? What is it about the dye that might affect the plant? etc etc...
Many things to consider. Just limit it.
