On 27/March/15 I bought some snow pea seeds and put 2 seeds in each cup.One cup had sand and the rest had soil. All of the cups had something different. One had no water and the other had no sunlight.One had sand instead of soil and the last one received sunlight, soil and water.

I will show you my results for the next 10 days:

After five days:

As you can see the no sun, everything and sand has sprouted.

Height:0cmtwo days after:

Height: 3cm

Height :7cm

Height: 10cm

After two days ,the plant in sand grew to 10cm, the plant with everything grew to 18cm, and the plant with no sun grew 20cm.

The following two days ,the plant in sand grew to 20cm, the plant with everything grew to 30cm, and the plant with no sun grew 35cm.

I learnt that water is more important than the sun. When I didn't add water to the plant and put it under the sun it did not grow at all. Snow peas that didn't get sun grew taller than the ones that got sun and water.
