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
