===Activity No #4 Why do objects feel heavy===
* '''Estimated Time''' - 30 minutes
* '''Materials/ Resources needed'''
#A piece of iron
#A piece of wood
#A ball of yarn or cotton
* '''Prerequisites/Instructions, if any'''
* '''Multimedia resources'''
* '''Website interactives/ links/ simulations'''
* '''Process (How to do the activity)'''
#Hold each object in your palm
#What do you feel when you hold each one of them (ask them to answer as light--->heavy)
* '''Developmental Questions (What discussion questions)'''
#Is there a difference when you hold each of them?
#Is this due to inertia? Am I changing anything when I am holding?
#What might this difference be due to?
#This is due to a property called weight which is because the mass of this object interacts with another mass - that of the earth. We call this weight
#We will study more about this - but mass also interacts with other masses; this is called gravitational property. We already saw that is has an inertial property
#The Earth is not touching the object, but still its mass has an effect on the mass on my hand
#Gravity can act at a distance between two masses
* '''Evaluation (Questions for assessment of the child)'''
#Does mass have both inertial and gravitational property?
#Does gravitational property depend on size? Or mass?
* '''Question Corner'''
#If an object has inertia, when I drop the object why does it fall?
#Do you feel the gravitational effect of the Earth?
* '''Estimated Time''' - 30 minutes
