Measuring Lung volume

 

Learners of Class VII measured their lung volume. They put water in a tub. They measured litre of water using measuring cylinder and created marks on a bottle. They inverted the bottle and place pipe's one end inside it. They blow air at a full pace and measured the volume of water remaining inside the bottle. 

They compared the lung volume among each other and learned scientific skills.  

Activity : Building the structure of atom

 Learners of Class VIII performed activity of making model of structure of atom. Learners have been given five elements on the board. They have to calculate the number of protons, neutrons and electrons in each element with the help of atomic number and mass number. Then they took three different coloured beads or pulses representing electron, proton, neutron. Using compass and pencil they made shells in their activity file. Then they pasted correct counted no. of sub atomic particles. The activity makes them clear about the structure of atom.
