HOW DOES MICROWAVE RADIATION AFFECT DIFFERENT ORGANISMS
By: Leticia Salas
RATIONALE
KJH Microwaves are basically extremely high frequency radio waves, and are made by various types of transmitter. "Cataracts" in your eyes, which is a clouding of the lens, preventing you from seeing clearly. Recent research indicates that microwaves from mobile phones can affect parts of your brain. “Microwaves are a form of "electromagnetic" radiation; that is, they are waves of electrical and magnetic energy moving together through space” (FDA Food and Drug Administration, 2014). I choose this project because it seems to be interesting in how the microwave radiation can affect fungi, bacteria, and plant life, in other words, living things. It is important for those who are using microwave radiation in their daily basis. And to know how much danger can microwave radiation can also affect in damage to us as living things. In bacteria, the heat of the microwave can kill them. “As far as I'm aware it is the heat that kill bacteria in a microwave, and they need quite some time to be dead. The spores that some kind of bacteria make to survive harsh conditions do not contain much water and they might survive microwaves. I'm not sure what bacteria do that can survive high dosis of radiation, like Deinococcus radiodurans. They can do this by a very efficient repair system for their DNA. My guess is that they would also be killed by the heat generated in a microwave but I haven't found any data on this.” (Wassenaar, 2012) Heating water on a microwave and putting it on the plants can affect the growth of them. “Microwaved water given to a plant causes the plant to wither and die within days. Microwaves can pass through walls, so if it’s placed against an adjacent wall, those on the other side will be exposed to higher levels of radiation.” (Stossel, 2011) Microwaves destroy the functions of all living systems which are based on natural electromagnetic fields. These radiations affect the living organisms through many different bodily systems. These include the surface area of the skin, the eyes via the retino-hypothalamic pathway, and the lungs by inbreathing irradiated air, and as we will see in detail, through the indigestion of irradiated food. Microwaves produce non-ionizing radiation. “Non-ionizing radiation doesn’t have the power to change your DNA and is not as dangerous as ionizing radiation”. (Beaumas, 2008) That is why it is important to know the effects that the microwaves can do to living things.
QUESTION
Does microwave radiation destroy all life?
Will varying lengths of radiation affect organisms differently?
HYPOTHESIS
I think that microwave radiation is going to affect this organisms.(kill them)
MATERIALS
1. Packet of radish seeds
2. Paper towels
3. Four small containers filled with sterilized potting soil
4. Four packets of bakers’ yeast
5. Four small bowls
6. Four prepared Petri dishes with agar (available from biological supply companies)
7. Sterilized swabs
8. Gloves
9. Microwave
10. Notepad and pen
11. Camera

RISKS AND SAFETY
You can get infected by a virus by touching bacteria. You can prevent all of this by using gloves.
PROCEDURE
1. Plant several radish seeds in a small container. Put them in a sunny, warm location. This is the control sample.
2. Place several more radish seeds on a paper towel. Microwave the seeds for five seconds.
3. Plant these seeds in another pot and place in the same location as the control group.
4. Repeat Step 2 and 3 for two more samples, except microwave one group of seeds for fifteen seconds and the other for thirty seconds.
5. Tend the samples by watering the pots once a day and ensuring they get enough sunlight.
6. Take pictures every day and note if and how quickly the samples grow.
7. Dump a packet of bakers’ yeast into a small bowl of warm water. Stir. This is the control sample.
8. Take note of how long it takes for the yeast to bubble up and how vigorous the reaction is. Take photos.
9. Dump another packet of bakers’ yeast onto a plate. Microwave for five seconds.
10. Mix this yeast into another bowl of warm water. Repeat Step 8.
11. Repeat steps 9 and 10 for the other packets of yeast, except microwave one sample for fifteen seconds and the other for thirty seconds.
12. Wearing gloves, use the sterilized swab to collect a sample of bacteria and swab it on a prepared Petri dish. Good places to find bacteria are areas where lots of people touch something, like doorknobs or faucets. Seal the dish and label it “control.” Put it in a warm, dark place. This is your control sample.
13. Swab another sample from the exact location as the control sample. Smear it on another Petri dish. Seal and label the dish. Place it in a warm, dark place.
14. Repeat Step 13 for the other two samples.
15. Let the samples alone overnight.
16. Take one sample out (not the control) and microwave it for five seconds. Place it back in the warm, dark place.
17. Repeat Step 16 for the other two samples, except microwave one for fifteen seconds and the other for thirty seconds.
18. After another day, take out all the samples. Note how many colonies of bacteria re growing and their size.

DATA ANALYSIS
RESULTS
The seeds that were microwaved for 5 seconds grew more than the seeds that also were microwaved, but with more amount of time (15 and 30 secs.) the seeds didnt grew that much
CONCLUSION
Microwave radiation can affect organisms as we watched before.
