image voltaic water heater. In its maximum hassle-loose style, all you like is a container (say a huge plastic milk bottle) that needs to be painted black. you are able to positioned this in the sunlight, and besides it yet another, unpainted bottle, the two packed with water. And diploma the water temperature after a pair hours. quite elementary, and is going to coach (harnessing basically a million/12'000th of the image voltaic capability that reaches the Earth might conceal all of mankind's capability needs). for sure, a container which would be wide and flat and nicely insulated, will artwork greater suitable than one it quite is be skinny and poorly insulated. Experiments could desire to be made with plastic (greater suitable insulator) or metallic (undesirable insulator). a greater suitable variety could nicely be geared up by putting a plastic pipe (say, backyard hose) in the form of exchange "S"'s in between to plastic sheets, the top one dark / painted black, and this might warmth water speedier, the water being in a bottle linked to the hose. however the project is which you may get the water circulating... by the way a professionally geared up version of it is in lots of circumstances used to conceal approximately 2 thirds of a relatives's warm water needs with a trifling 15 squarefeet of panels in step with individual (makes you ask your self why no longer each physique does it). greater state-of-the-artwork makes use of may be to construct a concave replicate to warmth water / prepare dinner meals yet this could nicely be a miles greater complicated project, previous the scope of a speedy severe college element. yet another thought may be to purchase a inexpensive / small photovoltaic cellular, and connect that to a motor, or a lamp, or some thing. yet i can not enable you comprehend the place to locate those on your section. desire this helps a

firstly select you want to explore the best part of physics and can go upto a bit higher level. acc. to me you shold make some logic gates and with this you can show that how they been used in computers. u can make working hydroelcetric engine. also can show the states of matter in which along with the three states you can show the fourth state that is plasma also . but you have to do a bit more study with plasma. as it working model is quite a difficult task you can use still model. you can also show how the LASER works and its properties . this could be a good fun.
