We are going to create Straw Rockets... Watch the clip: https://www.tvnz.co.nz/shows/kitchen-science/episodes/s1-e15 Equipment and Ingredients Drinking Straws Paper Pencil Scissors Clear tape/sticky tape Ruler Instructions 1. Cut a strip of paper 3 to 5cm wide. 2. Trim the strip so that it winds around a pencil once, to form a tube. Use sticky tape to hold the tube shape in place. 3. Remove the tube from the pencil and seal one end by folding over and securing with sticky tape. 4. Use the paper to cut out fin shapes and tape onto the sides of the rocket at the open end of the tube. 5. Place the rocket over the end of the straw and blow hard through the straw to launch it! Record your observations, go slow and look carefully! Scientists notice things and wonder what if... What happens when you change the flight path of your rocket? - Does it travel further if you point it straight up or straight out? Why do you think that is? Add another fin to your rocket. How does that change how your rocket flies? Why do you think this might be? Do you think you could make a larger rocket that fits over a kitchen roll tube? Will it fly if you blew through the tube? How could you find out?
