Science journal 2

We used balloons. We tied them onto a straw and through the straw went a string. The string a number was between two chairs, so when we blew up the balloon and let it go, it went along the string from the air coming out of the air hole. The learning in this was the forces that pushed the rocket balloon along the string e.g wind forces, thrusts and drag. I wonder what would happen if the wind was going the opposite direction and we changed the gradient of the chairs. On a rubric I am relational because I have lots of ideas and can make inferences.
