With the help of a few friends, I have decided to do my science project on:

"What types of soil affect the growth of one type of seed (e.g. tea leaves, gravel, coffee ground, etc.)"

I will use a few types of soil for one type of seed and over a couple of weeks, I will see how the plants grow. and how differently they will grow under the same conditions.

Again, here are the variables that will be used in this experiment:

Independent variable: the two or three different soils the plants are put in.

Controlled variable: the amount of water and light, same type of plant/seeds, same amount of soil for each plant/seed, same temperature and same planting pots.

Dependent variable: the growth and structure of the plants.

So now, I have to try and think of an experiment that will hopefully not take very long to do.

Over the next couple of hours and days, I will start researching different types of soils and how they affect the growth of seeds and I will post another blog and update what I have done.

I have to go now, BYE.
