What I Can Do STRAW WAVES Purpose: To create a DIY wave model. Materials: cello/adhesive tape, bunch of straws Procedure: 1. Stick straws at equal gaps on a 3-meter long sticky tape. 2. Stick another tape exactly on top of the previous one. 3. Press hard to stick the two tapes firmly. 4. Ask a friend to hold one end. Hold the other end of the tape tightly and twist the straws to make a wave. 5. Twist or flick one end to generate waves. Questions: 1. How do the waves travel if you hold tight the model when you flick it? 2. How do the waves travel if you hold loosely the model when you flick it? 3. What do you observe when you twist on both ends? 4. What is the role of energy in wave travel
