the lack of gun safety‚ many American children have died and have killed others. In the midst of all these tragedies‚ the parents of these children are held accountable for allowing this to happen. One example of this would be at an Earl Township Farm‚ where a 6 year old finds a shotgun with ammo‚ loads the shotgun and kills his 5 year old cousin‚ Andrew‚ who would probably still be alive if his cousin had been taught proper gun safety (Reilly 1). Children should be taught gun safety so that they know

Chemistry Revision F331 Isotopes - atoms with the same atomic number‚ but different mass numbers 131I - radioactive tracer for thyroid. 99Tc for tumours. Radioisotopes - gamma emitters & short half life - long enough to detect‚ but not long enough for damage. Beta particles emitters are more useful than alpha particle emitters because they penetrate more and so are more easily detected. Also‚ less damaging. The half life is the time taken for half the isotope to decay Mass left = initial

Give the reason for the following; Iodimetric titrations are usually performed in neutral or mildly alkaline (pH 8) to weakly acid solution. 2. Iodine solutions are prepared by dissolving I2 in a concentrated solution of potassium iodide. 3. Iodimetric determination of vitamin C is performed rapidly after preparing vitamin C solution

SCIENCE RATIONALE This syllabus is prepared with a view to address new trends in integrated science teaching and science teacher education. Science has gained world-wide acceptance as a course of study for various reasons such as the concern for social relevance and environmental issues. The teacher is seen‚ as the key to the success of the Educational Reform in Zambia and the effective implementation of the science curriculum will thus depend on the commitment‚ competence and resourcefulness

Gun Safety Children with parents who own fire arms should be taught how to act around‚ have self- control‚ and know the proper way to handle and control a fire arm. Knowing gun safety is very important part in a child’s life when their parents or legal guardian own fire arms‚ this is going to explain everything! There is a certain way to act around fire arms‚ there are many things to know and understand but the most important thing of all is to handle and treat all fire arms as if they are loaded

Editor’s Note: This occasional series of articles looks at the vital things in our lives and the chemistry they are made of. You are what you eat. But do you recall munching some molybdenum or snacking on selenium? Some 60 chemical elements are found in the body‚ but what all of them are doing there is still unknown. Roughly 96 percent of the mass of the human body is made up of just four elements: oxygen‚ carbon‚ hydrogen and nitrogen‚ with a lot of that in the form of water. The remaining
