We predict that the water rocket will We predict that the water rocket will launch higher than the air rocket launch higher than the air rocket

The reason why the water and air The reason why the water and air rocket are a lot different is rocket are a lot different is
because the water rocket goes because the water rocket goes higher and the air rocket goes higher and the air rocket goes lower. The water rocket went lower. The water rocket went higher because there were 80 higher because there were 80 psi’s of air that take up a lot of psi’s of air that take up a lot of
space, so when we added water space, so when we added water there was barely any space left!there was barely any space left!
In science we learned that when In science we learned that when you pump 80 psi’s and pour one you pump 80 psi’s and pour one cup of water in the rocket it gets cup of water in the rocket it gets
more pressure so it can go higher. more pressure so it can go higher. When you put in just the air in, it When you put in just the air in, it
doesn’t get as much pressure as it doesn’t get as much pressure as it does with the water in it.does with the water in it.
