Science Fair Project?

Will seeds germinate faster if they have been radiated in the microwave?

Hypothesis
If I expose different seeds to radiation from a microwave, then I expect them to sprout earlier than non-microwaved seeds, because fats and oils don’t absorb microwaves as well as water does. So the parts of the seeds that become the hottest are those that contain the most water molecules. Evidently, heating the water-containing portion of a seed slightly causes that seed to germinate faster.

Procedure
I will expose different seeds to different amounts of radiation from a microwave and plant them in soil. I will then observe the plants every day until the first one germinates and then I’ll record the time and date that the seeds germinated on. Next, I am going to compare the germination rates for different seeds that were exposed to different amounts of radiation from the microwave. Finally, I will determine the amount of radiation needed to cause seeds to germinate the fastest.
