Gold Dust and Radish Seeds
Medium
We're testing to see if gold dust affects the germination rate of radish seeds. We'll measure the rate of germination and percentage of seeds germinated for each group of petri dishes with different amounts of gold.
Hypothesis
The hypothesis is that the larger amounts of gold will not increase the germination rate of the radish seeds.
Method & Materials
You will place 100 radish seeds into each of 12 petri dishes, pour a mixture of water and gold powder over the seeds, and document any changes in the seed's germination each day.
You will need 12 petri dishes, 100 radish seeds, filter paper, 25 ml of water, and 0.25 gram of powdered gold.
Results
The results showed that the seeds in the petri dishes that contained no gold germinated at a faster rate and had a higher percentage of seed germination than the other groups of petri dishes. The germination rate and percentage of seeds germinated decreased as the amount of gold in each pair of petri dishes increased.
Why do this project?
This science project is interesting because it tests the effects of gold powder on the growth of radish seeds, which is something that has not been studied before.
Also Consider
Experiment variations to consider include testing different types of seeds or different amounts of gold powder.
