- 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?
- If I stop holding, what happens? Will it fall?
- Have you ever seen something fallen from a height - or even a fruit from a tree?
- If it is changing its position and moving (falling) there must be a force?
- Where do you think the force is coming from?
- Is it possible that forces can also act without touching?
