Germination experiment Essay Example for Free

Germination experiment Essay Method: 1. Put some soil in every beaker and make sure it is almost the same amount 2. Place 5 beans inside each beaker at the same level beneath the soil 3. Pour 10, 20, 30, 40 and 50 ml of water in each beaker respectively and keep watering them every 2 days 4. Leave the beakers close to a good light source 5. After a week record the length of the stem of the plants in each beaker Variables: 1. Dependant: Height and growth of the plants 2. Independent: Amount of water 3. Controlled: Where the beakers are placed, amount of soil, amount of seeds, type of seeds, how often the plats are watered (Initially it was decided that the amount of water we would use would be 50, 100, 150, 200 and 250 ml but we decided to lower the amount of water so that the plants wouldn’t drown) Results: amount of water (ml) Length of plants (cm) average length (cm) Â   Conclusion: The first thing we can see from the results is a boundary in the amount of water in relation with the beaker size and the amount of soil. In the table we can see that after the 20ml of water the seeds drowned and so they didn’t grew at all. But if we take in comparison the length of the plants in the beaker with 20ml with the one with 10ml we can see that with more water the germination takes place faster. For example in the results table we have the average growth of the plant of about 10. 5 cm and in the 20ml an average growth of 17. 8, so evidently we can say that the hight the amount of water, the faster the seeds will germinate and the higher they will grow. Evaluation: I think that in general this experiment was carried out fairly in terms of the type of seed, thay were kept in a well lit place, all the beakers had the same soil and the same amount of it, etc. The problem was that the plants were drowned so we couldn’t get a good set of results, so if he experiment had to be carried out again I would set a limit of water to allow the plants to actualy germinate.
