Activities

Lesson Plan version 1.1 activities
1. Take three bowls. Pour very cold water in the first bowl. (you can also add ice cube for cooling). Place luke warm water in the second. Half fill the third with hot water (-not hot enough to burn!) Set them in a row on the table, with the lukewarm water in the center. Place your right hand in the cold water, and your left hand in the hot water. Keep them in for a few minutes. Then take them out, shake off the water and put both into the middle bowl. How do they feel?
2. The Temperature of Boiling Water Take water in a vessel and place the vessel on a stove. Fix the thermometer as shown in figure All students have to read the temperature of the water and note the reading on the blackboard. Do you notice that the temperature is raising?
3. Take one litre water in a pan, and heat it on a stove. Calculate the time taken to start boiling. (i.e. the time taken to thermometer reading goes up to 100oC). Take five litre water in another pan and heat it on the same stove. Calculate the time taken by the water to start boiling.
4. Hammer a nail into a tin can. Ease the nail out. Put it in again to make sure that the hole is large enough for the nail. Then, holding the nail with a pair of pliers, scissors or forceps, heat the nail over a candle, in hot water, or over the stove. Try to put it into the hole in the can.
5. Linear Expansion- Take a bulb, dry cell, candle, cycle spoke, coin (or broad - headed nail) and two wooden blocks. Place one end of the cycle spoke on a wooden block and connect an electric wire to it. Put a stone over the spoke to hold it firmly in place on the wooden blockas shown in Figure . The spoke should be parallel to the ground. Place the second wooden block under the free end of the spoke. Wrap some electric wire around the coin (or nail) and place it on the block. You may put a stone over the coin to hold it in place. Connect a bulb and dry cell to the free ends of the wires connected to the coin and the spoke and make the circuit
6. Cubical Expansion- Take a metal ring and metal ball of such size that the ball just passes through the ring.
Heat the ball and check whether it passes through the ring.
Passed through
Not passed through
Now let the ball cool down, and check whether it passes through the ring. Passed through Not passed through Solids expand due to heat and come back to the original state if heat is removed.
