1. Environmental Effects of Radiation

2. Purpose:
To see the effects of seed irradiation on germination and plant growth.

3. Irradiation may prove to be detrimental to the seeds.
Lack of germination, stunted growth the stem and overall seedling length, loss of chlorophyll, change in color.
Irradiation my prove to be beneficial to the seeds.
Resistance to disease, drought, abnormal weather, increase growth rate

4. Investigation Question
What effect does___________have on_______?
What effect does increasing levels of radiation have on germination and seedling growth of radish seeds?

5. Design Experiment
Remember to only change one variable!

6. Data Collection Levels of Radiation (Rads) Length of Seedling (mm)
