## Process (How to do the activity)

Open PhET simulation called Energy forms and changes.

• Drag water beaker on heat stand
• Drag brick on other heat stand
• Drag the thermometers close water as well as brick
• Click on energy symbol
• Heat and cool the water beaker by dragging the icon towards heat and cooling symbol
• Observe the change in energy level of water as well as thermometer
• Note down the changes in your book
• Drag the iron block on the heating stand..
• Heat and cool the iron by dragging the icon towards heat and cooling symbol
• Note down the changes.
• Heat and cool the brick by dragging the icon towards heat and cooling symbol
• Observe the heating and cooling level of both iron and brick
• Compare the heating and cooling capacity of water , iron and bricks

## Developmental Questions (What discussion questions)

1. What change do you observe?
2. what is the level of temperature in fig 1.0,1.1 and 1.2?
3. What is cooling?
4. Among the 3 objects which has more capacity to expand while heating?
5. what is the S.I unit of energy?
6. Among the 3 which object stores more energy?
7. Why the reading of thermometer does not show beyond 100 °c while heating of water?
8. Do the iron have melts?

## Evaluation (Questions for assessment of the child)

1. What are the 3 states of matter?
2. What is thermometer?
3. What are the effects of heat?
4. what is the boiling point of water?
5. Among the 3 which form of object changes its state faster?
6. Name the object which does not expand on heating and cooling?
