Experiment

I have come up with an experiment draft on how to test my question: (I may have to change this experiment a little bit, though)

Aim:

To examine whether different types of soil affect the growth of one type of seed.

Hypothesis:

The soil with the more nutrients will affect the growth and height of the plant that it will grow quicker and taller than the ones without as many nutrients.

Equipment/Materials:

3 buckets to hold the experiment in

· 1 sharpie and paper for labeling the plants

Water for watering the plants on a regular basis

A number of snow pea seeds which are going to be put into the buckets to grow

3 types of soils: (POSSIBILITIES) soil from the bush, organic soil and soil from a backyard


Method:
1. Buy and collect all the equipment required for this experiment.
2. Add 1/3 a bucket full of soil from the bush into the bucket.
3. Plant the snow pea seeds within the soil.
4. Water the soil.
5. Repeat steps 2-4 for organic soil and backyard soil.
6. Water the each of the plants daily, making sure the soil is always full of moisture.
7. Observe and record the results of the growth of the plant every 2 days.
8. Compare the results when the period of time for the snow peas to grow finishes.

So far, this is all I have for my SRP, but I may need to make a few changes to it and I might change the type of seed I want to use for my experiment, but this is the general idea for my project. I went to this site which did a similar experiment to the one I am about to do:
http://www.usc.edu/CSSF/History/2006/Projects/S1619.pdf
However, I will be doing it slightly different to it this experiment as I will be using different soils and a different type of seed and based on this site, I will see if the conclusion will match mine when I do finish the experiment.

That is all for now, GOODBYE.


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.

I have researched and thought further into my ideas:

What types of soil affect the growth of one type of seed:

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

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

Dependent variable: the growth and structure of the plants.

Does the colour of light have an affect on the growth rate of a plant?:

Independent variable: the different colours of light subjected to the plant.

Controlled variable: the same plants, the plants are put into the same environment, everything else that is done to the plants, like watering, are done at the same time.

Dependent variable: the height or structure of the plant after the period of time for the experiment.

Does the amount of light have an affect on the growth of plants?

Independent variable: the different amount of light that the plant is subjected to.

Controlled variable: the same plants, the same time they are watered and the same things are done to both of the plants.

Dependent variable: the height and growth of the plants a certain period of time.

Here are some independent, dependent and controlled variables that I have thought of for the different ideas for my project. However, think some of the ideas I have researched and thought of are either too simple or cannot be done without the proper equipment needed which I have.

I will be back on later, to decide which one I have decided to do for my project.

BYE.

i have researched and thought of some ideas for my assignment such as:


  • What types of soil affect the growth of seeds (e.g. tea leaves, gravel, coffee ground, etc.)
  • Does packaging affect the ripening of fruit?
  • effect of cigarette smoke on plants
  • does the colour of light have an affect on the growth rate of a plant?
  • will plants grow better when subjected to music?
  • does the amount of light have an affect on the growth of plants?
but i am not very sure which one to use. I will be back later to choose my actual idea for my project.

bye.
