The Importance of Nature in a Child’s Life Nature is made by nature‚ not by man. Nature can be used for many different things. It can be used for a natural playground‚ a learning experience‚ a science experience‚ a meditation place. The list is endless on what nature can be used for. The best part about it is that there is no list that states what it can and can’t be. It is all in your imagination. This is important for children to learn and grow with. Without nature‚ there would be no land to live

I woke up and the bedroom was hot.I guess the power still hasn’t been fixed yet. It drives me crasy with no heating on a bloody winters day in the middle of December! I slowly slip out of bed still clutching my blanket for some warmth. I climb down the ladder and as soon as me feet touch the ground I quickly jump onto the carpet. The floor is like a sheet of frozen ice. No floor heating either. Great! Well‚ at least something can keep me awake in the morning at quarter to six. I’m just about to

Electricity is the set of physical phenomena associated with the presence and flow of electric charge. Electricity gives a wide variety of well- know effects such as lightning‚ static electricity‚ electro magnetic induction and the flow of electrical current. In addition‚ electricity permits the creation and reception of electromagnetic radiation such as radio waves. Electrical phenomena have been studied since antiquity‚ though advances in the science were not made until the seventeenth and eighteenth

Atomic Structure & Electricity 1. Draw an atom with an atomic number of 12. Label the protons‚ neutrons‚ and electrons. Use the periodic table to identify which atom you have drawn. 2. How many valence electrons are present in this atom? 2 3. Would this atom prefer to gain or lose electrons? Why? Lose‚ because the octet rule dictates that if there is less than 4 valance electrons‚ they would prefer to leave the atom. 4. Describe the differences between conductors‚ semiconductors

Hazards of Static Electricity; Lightning Lightning is a massive electrostatic discharge between the electrically charged regions within clouds or between a cloud and the surface of a planet. It is the sudden high-current discharge caused by the atmosphere’s electrical breakdown. Lightning is also one of the most deadly natural phenomena known to man. Lightning is an electric current; thus within a thundercloud up in the sky‚ many small bits of ice (frozen raindrops) collide into each other as

abiding by certain rules and regulations of social life. Discipline is what a person imposes on themself and sticks to as strongly as one would follow the law. It enforces a strict control over an individual’s rights and privilege. Discip¬line is vital to a successful life.
