Light travels in a straight line.
Ãƒâ€šÃ‚Â Students were divided into groups of 5 and were given different materials like cardboard, torch and a CD rack. Students were instructed to explore the material. Later they were instructed to use and arrange the given card boards in such a way that light passes through each of the card board. After this activity teacher took an inquiry and students reflected that when they made holes in the same place in all the card boards and arranged them in a straight line, they were able to see the light passing from one end to the other.
Sound can pass through solid and liquid
To introduce this property the experiments were divided:
1st experiment: students kept their ear on the table and from the other end of the table one sound like tapping was made by other student. This proved that sound can pass through solid material.
2nd experiment: students were given an object Ãƒâ€šÃ‚Â like bell and Ãƒâ€šÃ‚Â water bucket. They kept the bell inside the water and tried to listen to the sound. This proved that sound can pass through liquid as well.
