Investigative project

                    Investigation on how microwaved water can affect the growth of seeds

Mission: Our experiment is to see how dangerous microwave radiation is to people, so we want to find how microwave radiation affects the growth of seeds. This would show how can microwaved food can affect the growth of humans who eat microwaved food and with this data we can see how bad is microwaved food to us

Why do we want to do this?

Why should we do this to prove that microwave is harmful to living things?

How can this benefit all of us?

Our project focuses a lot on a persons own health. We chose water because we want to emphasise the fact that water is an indispensable item in life, and we are trying to prove that we should use water on its own, and not alter the water in any way. We are also trying to say that we should not take water for granted. We have to know that water is the essence of all life. Even the germination of seeds requires water. We are trying to convince people not to microwave water as it would be harmful to our health. Our research has shown that the water that has been microwaved will cause the seeds to not germinate. Pure water on the other hand, will result in the seeds becoming a shoot. So, microwaved water cannot be used in many different aspects of life. So, we should take water for granted and conserve and use water wisely. We have found out that the water that has been microwaved is harmful as the microwave uses a non-ionizing form of radiation to heat up the water. When the water is fed to the seed, the seed will naturally absorb the water and the radiation. It is highly carcinogenic and can provoke the plant and create and random form of cancer in it, causing it to die or not germinate. The carcinogenic toxins will leak out of the plastic and containers, into the food. Research shows that your microwave oven will NOT help us in these efforts – and in fact will threaten our health by violently ripping the molecules in your food apart, rendering some nutrients inert, at best, and carcinogenic at its worst.

This would help us all so that we can know of the microwave’s bad effects and try to use the microwave less often. We could instead cook our food with a stove as the microwave radiation can change our food into something that is not healthy. So this would help us encourage other people to use the microwave less as water is found in most of the things we microwave so if it affects the plants, won’t it affect us too? So this is why we want to do this so that people that use the microwave often would use it less and do less harm to themselves and lead a healthier lifestyle by taking in less food that may be carcinogenic so we should use the microwave less and cook food with the stove and live a healthy lifestyle.

Variable

Type of Variable

How is it changed, measured or kept the same

Time in microwave oven (soil)

Independent

Changed by putting the soil in the microwave for different lengths of time.

Time in microwave oven (water)

independent

Changed by putting the water in the microwave for different lengths of time.

Amount of seeds

Constant

Kept the same by counting the amount of seeds in each pot.

Type of seed

Constant

Kept the same by getting the seeds from the same packet.

Age of seed

Constant

Kept the same by getting the seeds from the same packet.

Amount of water

Constant

Kept the same by measuring the amount of water used to water the bean seeds and using the same amount.

Amount of light

Constant

Kept the same by putting all the pots near each other.

Temperature

Constant

Kept the same by putting all the pot near each other.

How fast the seeds germinate

Dependent

Using a timer

How tall the seeds grow

Dependent

Using the same ruler

Hypothesis: We expect that the seeds that are microwaved germinate slower and the shoot is shorter when they are microwaved longer.

Equipment list

9 300 ml plastic containers

900g of garden soil

Measuring beaker

54 green bean seeds

Microwave( at team members house)

3780 ml of water

Weighing scale

6 containers for water

7 pairs of disposable gloves

2 heating lamps.

Steps:

1 i)Microwave 100g of soil for 15 seconds

 ii)Microwave 100g of soil for 30 seconds

iii)Microwave 100g of soil for 45 seconds

iv)Microwave 100g of soil for 60 seconds

2.i)Microwave 210 ml of water for 15 seconds  

ii)Microwave 210 ml of water for 30 seconds  

iii)Microwave 210 ml of water for 45 seconds  

iv)Microwave 210 ml of water for 60 seconds  

3.Put 100 g of non-microwaved soil into 5 beakers(5,6,7,8,control) and put the 100g microwaved soil that have been microwaved for 15,30,45,60 seconds into 4 beakers respectively (1,2,3,4)

4.Then put 6 non-microwaved green bean seeds into each beaker

5.Pour 30 ml of water into each of the 4 beakers everyday(1,2,3,4,)

6.Pour 30 ml of water that has been microwaved for 15,30,45,60 seconds into the 4 beakers respectively everyday(5,6,7,8)

7.Pour 30 ml of non-microwaved water into the beakers that have the microwaved soil(1,2,3,4)

8.Have a control with non-microwaved water and soil and give it 30 ml of non-microwaved water everyday(9)

Note Put heating lamps so it has enough light and warmth

9.Observe when the seeds starts to germinate and record your findings. If all the seeds germinate, record the height of the shoots.

Risk and Safety:

We might get burned by the bowl when we take it out of the microwave

The water might be hot and we might get scalded if we spill it

The plastic containers may cut us

Data analysis:

We will see how long each seed takes to germinate and record the height of each plant and record it down, then we will take the average of the six seeds in the container and compare the results with the other results and see if the longer the water is microwaved the seed takes longer to germinate or do not germinate at all and when it germinates see if the shoot is shorter when it is microwaved longer.

Table for findings:
