physics activities for elementary students

Take a nichrome wire of about 50 cm length and apply a potential difference of 1.5 V from a battery. Measure the current flowing through the wire using an ammeter connected to it in series, and note the potential difference across the resistance using a voltmeter connected across it. Note down and ..

Elementary Idea of Electron Microscope - In optical microscope, the ray of light can be bent by a lens system. By placing the object and the lens system in such a way, we control the direction of the ray to get a magnified image of the object. Since as 'electron' carriers charge it is pos..

The fan driven by an electric motor reduces the pressure near the mouthpiece. The pressure due to atmosphere being large, forces air along with dust particles into the long tube and then, into the bag. The fan forces the air out of the sweepe..

In many instances, the most convenient unit for specifying the amount of a substance is the mole, where 1 mole = 6.023 x 10 2 3 elementary units of any substance. Thus, 1 mole of aluminum means 6.023 x 10 2 3 atoms (the atom being the elementary unit), and 1 mol of aluminum oxid..
