Conclusion
Conclusion: In this experiment, my hypothesis was correct. I predicted that the more sugar added into water the germination would decrease because it would be to sweet for the alfalfa seed to germinate. From my observation and data, the alfalfa seed had the highest percentage of germination in water with 100% and water containing 5 ml of sugar dissolved in it with 64%. While the alfalfa seed had the lowest percentage of germination in water containing 10 ml of sugar with 58% and 15 ml of sugar with 40%. The scientific explanation for this could be because of osmosis. The water molecules in the cup is moving from a higher to a lower water concentration through the seed. Meaning the sugar molecules in the water won’t be able to pass through the seed in the solution, having an effect on the alfalfa seeds growth. Instead of only having one trial, testing with two cups rather than one for each of the following containing 5 ml, 10 ml, and 15 ml of sugar in the 30 ml of water would make the data more reliable. From this data, it proves that water containing more sugar affects the germination of the alfalfa seed by decreasing it.
Error Analysis: Some of the possible reasons why the data for this lab wasn't precise or as accurate was because the seeds could have been old and dead. Also some cups might have had different amount of sunlight exposure compared to the others.
