| Video Discription | 1. Use a thread, straw, balloon and two-way tape for this activity. 2. Pass a thread through the straw and tie the thread to the two poles or stand. If two fixed poles or stands are not available, 2 students can hold the thread at their shoulder level. The Students should keep the string taut (or tight, i.e. without any slack). 3. Now push the straw from one end to another end with all your force 4. How far has your straw travelled? 5. Now let’s try something interesting; blow a balloon and stick a two way tape to it without tying or releasing its mouth. 6. Now, stick the balloon on the straw using a two way tape, ensure you are still holding balloon’s mouth so that no air escapes. 7. Once the balloon is stuck properly, release it and observe your straw. 8. The straw rushes to other end of string. 9. We use muscular force to push the straw with our hands. We also use muscular force of our lungs to blow the balloon. The balloon uses mechanical force by releasing a continuous stream of air to move the straw. 10. In this small experiment we learnt to use both these forces to get our straw from one end to another. STUDENT’S LEARNING: • Mechanical and Muscular Force [bB6JP8ppFTo] |
