Why Is Plagiarism Illegal?Plagiarism is illegal because plagiarizing something is the same thing as stealing someone elses property. It may not seem like it is stealing but it is because you are taking someones ideas/ work and passing it as yours when it isn't. My Promise:I understand it is wrong to copy someone elses work and claim it as my own. My research project final product, details and presentations are my own work and words.

1) Research Questions: [Draft questions that address your research problem.] How does microwave radiation affects different organism?

2) Hypothesis: [Draft a hypothesis to answer the question using an if then .. because format]If microwave radiation affects the yeast, then 30 seconds micro waved yeast will have the most bubbles because it applies to heat, which makes easier to have bubbles.If microwave radiation affects the plants, then 30 seconds micro waved will grow faster than other samples because it gets warmer, meaning they dont need to receive much sunlight as others.If microwave radiation affects the bacteria, then 30 seconds micro waved bacteria will have the least colonies because it irradiates the bacteria itself and kills it.

3) Research Objective: [What is the purpose of your research?]

The purpose of the lab was to determine how the microwave radiation affects different organisms. In order to find out the effects of microwave performed an experiment using two different organisms: Radish seeds and yeast

4) List of Materials: [List all the materials that you will need to complete your project.] Microwave Camera Notebook and pen Four small containers filled with sterilized potting soil Four packet of baker yeast Four small bowls Four prepared Petri dish with agar Sterilized swabs Packet of radish seeds Plate5) Experimental Procedure: Plant several radish seeds in a small container. Put them in a sunny warm location. This is the control sample Place several more radish seeds on a paper towel. Microwave the seeds for five seconds. Plants these seeds in another pot and place in the same location as the control group. Repeat step 2 and 3 for two more samples, except microwave one group of seeds for fifteen second and other for 30 seconds Tend the samples by watering the pots once a day and ensuring enough sunlight Take a picture everyday and note if and how quickly the samples grow. Dump a packet of bakers yeast into a small bowl of warm water. Stir .this is the control sample Take a note of how long it takes for the yeast to bubble up and how vigorous the reaction is. Take photos Dump another packet of bakers yeast onto a plate. Microwave for five seconds. Mix this yeast into another bowl of warm water. Repeat step 8 Repeat step 9 and 10 for other packets of yeast, except microwave one sample for fifteen seconds and the other for thirty seconds. 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. 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. Repeat step 13 for the other two samples. Let the samples alone overnight Take one sample out (not the control) and microwave it for five seconds. Place it back in the warm dark room Repeat step 16 for the other two samples, except microwave one for fifteen seconds and the other is for thirty seconds. After another day take out all the samples. Notes how many colonies of bacteria are growing and their size.

As you Conduct Experiment when you do your experiment you need to collect data and make observations. You will complete these in your Experiment Log. After you have completed the experiment use your log to write down the data and observations below. In your log you will need to: 1. Collect Data - you will need to collect numerical data; that means you need to take measurements during the experiment. It can be temperature, distance, height, etc. You will analyze the data later to determine the results of your experiment. 2. Make Observations - as you conduct your experiment you will use your senses (sight, smell, touch, etc.) and write down any observations you make during the process. 6) Data Table:DAY / DateMy Evidences: Pictures / diagrams / images / details of subject (people)My Observations:

7) Results: [Review your data and observations to find out what happened. Think about the best way to show your data: bar graph, line graph, chart, etc.]

8) Conclusions:The purpose of the lab was to determine how the microwave radiation affects different organisms. In order to find out the effects of microwave performed an experiment using two different organisms: Radish seeds and yeastAccording to my experiment using radish seeds the facts that overall growth was shorter than the seeds that germinated naturally was noticed. The microwave radiation heated up the water molecule inside the seeds slightly which weakened the seed coats and allowed water to penetrate and kill the seeds.From the result of yeast I realized that microwaves are able to absorb by water, fat and sugars. The main components of the foods we eat. When the microwaves go inside the food they thrill the molecules in the food and make them move very fast. The movement in the food of the molecule causes the food to heat up all over.

a. Answer to your original question: How does microwave radiation affects different organism?Radiation is often categorized as either ionizing radiation or non-ionizing radiation depending on the energy of the radiated particles. In ionizing radiation this energy is more than 10 eV, enough to ionize atoms and molecules, and break chemical bondsb. Was your hypothesis correct or incorrect? If incorrect, why? Yes it was correct c. If you were to complete this experiment again, what changes would you make? How would you improve this experiment? I will add more good materials related to this experiment and make even more better than this next time
