Learning Task 1: Balloon Rocket Objective: Describe how a balloon rocket works and how conservation of momentum explains rocket motion. Materials: balloon (long shape, if available) drinking straw, string (nylon, if available), and adhesive tape Procedure: 1. Stretch the string over two posts. You can use chairs or iron stands as posts. Make sure that the string is taut. 2. Inflate the balloon. Twist the open end and temporarily secure it with a paper clip. 3. Tape the straw to the balloon such that it is aligned with the balloon's opening (see Figure 3). Figure 3. Balloon rocket set up. 4. Draw a diagram showing the momentum vectors of your balloon rocket and the air. Questions: 1. How do these momenta compare? 2. How does the velocity of the air that is pushed out of the rocket compared to the velocity of the balloon rocket
