Questions

Why do you think the first one was a success?

• Plants used have high level of tolerance 
• The amount of water is enough for the tree to survive and grow together 
• The shape of the cut is a perfect fit that allows the two parts to combine together

Nuclear Power

We support nuclear power

“Nuclear power is the use of nuclear reactions that release nuclear energy to generate heat, which most frequently is then used in steam turbines to produce electricity in a nuclear power plant.”

Reliable

It is estimated that with the current rate of consumption of uranium, we have enough uranium for another 70-80 years. A nuclear power plant when in the mode of producing energy can run uninterrupted for a very long time. As solar and wind energy are dependent upon weather conditions, nuclear power plant does not, and, therefore, can be used in any condition.

Ecofriendly

Nuclear power also has a lot fewer greenhouse emissions. It has been determined that the amount of greenhouse gases have decreased by almost half because of the prevalence in the utilization of nuclear power. Nuclear energy has the least effect on nature since it doesn’t produce any greenhouse gases. There is no unfavorable impact on water, land or any territories because of the utilization of nuclear power, except in times where transportation is utilized. Therefore, it produces very low pollution to the environment.

Low Cost

Nuclear power produces very inexpensive electricity. The cost of the uranium is low. Also, the expense of setting up nuclear power plants may be moderately high, the expense of running them is quite low. The normal life of nuclear reactor is 40-60 years. These variables make the expense of delivering power low.

Euthanasia

Euthanasia should be allowed

Euthanasia is an act of putting to death painlessly or allowing to die, as by withholding extreme medical measures, a person suffering from an incurable condition.

Euthanasia saves life

In the Netherlands, "a study of euthanasia found that 0.4% of all euthanasia was done without consent from the patient. The study was done when euthanasia had been legalized in the Netherlands. Now another study, which was done before euthanasia was legalized, indicated that 0.8% of euthanasia done in the Netherlands was done without the patient's consent." This shows that the legalization of euthanasia actually had the reverse of the expected effect. The number of euthanasia done decreased by half after the euthanasia was legalized.

Euthanasia is properly regulated

Developed nations like the Netherlands have legalized euthanasia and have hardly ever had problems. "Any law or system can be abused, but that law and the system can always be refined to prevent such abuse from happening". Therefore, euthanasia will be better with regulation.

Euthanasia does no harm to others

There are ideas supporting and conflicting euthanasia. The conflict leads the government to consider the rights of people that are violated when euthanasia is applied. That being said, euthanasia as a choice infringes on no such fundamental rights. Assisted suicide involves direct harm and the termination of life only to the individual who has requested it. One cannot request euthanasia for another person. Therefore, euthanasia does no harm to others.

People have right to die

Anti-euthanasia proponents argue that euthanasia infringes on a person’s fundamental right to live. What they fail to see is that our “life” as human beings implies death. Without death, we do not have “human life” by its very definition. Therefore, people who argue that every man has the fundamental right to live, they also agree that every man has the fundamental right to die. At the end, people have the right to die, and euthanasia should be allowed.

Grafting

Grafting

Procedure 
1. Sharpen your knife
2. In one stroke make a long, smooth cut angling across an internode at the top of the rootstock 
3. Make a cut of the same length and angle across the base of the scion.
4. Check that these cuts match.
5. Make the tongues. 
6. Slide the scion and stock together to interlock. 
7. Bind and seal the graft

Fruit Batteries

Fruit Batteries 

Materials 

• fruits or vegetables 
• metals 
• voltmeter 
• ammeter 

Purpose 

• The purpose of this experiment is to determine the electrical voltage output of different combinations of electrodes and fruits 
• It is also to find out which fruits give the highest voltage outputs 
• It is also to find out if the separation of the electrodes affects the voltage output 
• It is also to find out the voltages given off by different pairs of electrode materials 
• It is also to examines the voltage puts when the electrodes are connected in series and in parallel 
• It is also to find the amperage output of different pairs of electrodes 
• It will also examine whether the depth the electrode is inserted into the fruit affects either the voltage or amperage outputs 

Procedure 

Roll the fruit a little to make it a little juicier in the inside. Insert one electrode material into the juicy part of the fruit. Insert the second electrode into the juicy part of the fruit, but not so the two electrodes touch. 

Result 

1) Does the distance between the electrodes affect the voltage? 

 2) Does the distance between the electrodes affect the amperage?

 3)Does the type of fruit affect the voltage?

 4) Does the type of fruit affect the amperage?
