What an interesting project! I wonder what made the Mentos and Coke so much less effective than the other fuel sources? I also would have expected the water and air pressure rocket to fly the highest, so it’s very interesting that it didn’t.
You used a 30-foot baseline and an angle gauge with a real trigonometry formula to calculate how high your rocket went. That is a physics measurement system, not a guess.
You got a result that proved your hypothesis wrong, said so clearly, and then explained exactly why the Coke and Mentos failed. That takes confidence, and that is good science.
Your research paper documents each trial with a date, time, and your own observations written that day. That is exactly what a lab notebook is supposed to look like.
