CLASS VII INVESTIGATING DIFFUSION, PRESSURE IN LIQUIDS

 





Learners of class VII performed individual activity in which they investigated how depth affects pressure in liquids. They have taken an empty water bottle and made three holes on one side of the bottle. They filled the water and observed that the from the bottom hole  water is running with maximum pressure. They also have done the investigation of how temperature of water affects rate of diffusion. They had taken cold, hot and room temperature water. They dropped ink in the glasses of water and noted time in which the ink diffused in water.
