Gravitation Activity 4 An example of force at a distance

Activity No #4 Why do objects feel heavy

 * Estimated Time - 30 minutes
 * Materials/ Resources needed
 * 1) A piece of iron
 * 2) A piece of wood
 * 3) A ball of yarn or cotton
 * Prerequisites/Instructions, if any
 * Multimedia resources
 * Website interactives/ links/ simulations
 * Process (How to do the activity)
 * 1) Hold each object in your palm
 * 2) What do you feel when you hold each one of them (ask them to answer as light--->heavy)
 * Developmental Questions (What discussion questions)
 * 1) Is there a difference when you hold each of them?
 * 2) Is this due to inertia? Am I changing anything when I am holding?
 * 3) If I stop holding, what happens? Will it fall?
 * 4) Have you ever seen something fallen from a height - or even a fruit from a tree?
 * 5) If it is changing its position and moving (falling) there must be a force?
 * 6) Where do you think the force is coming from?
 * 7) Is it possible that forces can also act without touching?
