class v starch test before and after chewing food
The starch test activity was performed by class v students on potato and the chappati in their lunch box. Students found the yellowish brown iodine solution turns to blue black in colour with starch.
After chewing the chappati for a long time in the mouth and putting iodine on it does not change colour to blue-black as saliva digest starch into sugar.
CLASS VI STATE CHANGE
Students performed an activity to measure the temperature of water at the state change into steam. They learnt all the apparatus required for the experiment and noted down the reading of temperature after every minute. The graph was also plotted by students using readings. They observed a steep rise of temperature in the beginning but it cures and become fairly static as the state change occurs.
