Raadish Seeds Lab

During the Toxicity of Morton Salt on Radish Seeds experiment, we measured the levels of iodized Morton Salt to the growth rate of radish seeds. Each six packets had ten radish seeds with different level of iodized salt solution. The packet with no iodized salt solution grew the longest in a period of days, compared to the other packets that had iodized salt. Solutions 100% and 10% had no growth progress within the past five days. As for solutions 1%, .1%, and .01% grew, yet not as much nor fast as the packet with 0% of iodized salt. Before these results, we predicted that as the concentration of Morton’s plain salt increases in the solution used to keep the radish seeds moist, germination will yield shorter plant roots and shoots. Reviewing our results, the more iodized salt added to the radish seeds the longer it took for the seeds to grow. Based on our data our hypothesis is supported, as the more salt added germinating the seeds slowed the plants ability to grow.
This can affect the experiment due to the size of the teaspoon and the amount of solution that was added to the radish seeds. Another error within measurement would be the different way of measuring each radish seed. I admit that, after measuring so many seeds, I got confused with the measurement of growth and the actual measurement of the seed itself. This could affect the result in the accuracy of growth rate within each salt solution. As well as making sure that the control group is controlled throughout the experiment. This could affect the result within the conclusion of deciding if the hypothesis is supported or
