Group Activity Prepare a model to demonstrate movement of particles in solids, liquids and gases. For making this model you will need A transparent jar A big rubber balloon or piece of stretchable rubber sheet A string Few chickpeas or black gram or dry green peas. How to make? Put the seeds in the jar. Sew the string to the centre of the rubber sheet and put some tape to keep it tied securely. Stretch and tie the rubber sheet on the mouth of the jar. Your model is ready. Now run your fingers up and down the string by first tugging at it slowly and then rapidly. Fig. 1.10: A model for converting of solid to liquid and liquid to gas.
