Today we started to build our rockets launch pad. The launch pad will be two pipes on top of the t shaped launch pad. These pipes will have a hose going through it to have the water flowing through it. We used PVC cement to hold most of the parts together.
When making rocket fuel we used two different methods; gunpowder and rocket candy. We wanted to see which would work better with the rockets. When making the gunpowder we used 1 gram Carbon, 1 gram Sulfur, and 1 gram Potassium Nitrate ground down to a fine powder. The result was that the flame was small but easy to light. We tried again with the the powder not being as finely ground down and the powder was not as easily lite. Our conclusion was that the finer the powder the easier it is to light.
Today we tested for average velocity and we had to use the formula Displacement over Change in Time. We also we looking for the relationship between the launch angle and the average velocity. In doing so we made a scatter plot of the launch angle and the average velocity.
Today we tested the launch angels and if the lower angel will shoot further than the higher angle. My hypothesis is that the lower the angle the further the rocket will travel. The independent variable is the angle of the launch and the dependent variable is the distance traveled. The conclusion was that my hypothesis was correct and the rocket traveled further when the angle was at its lowest.
I edited my website and added the engineering process. I also labeled what each step does and how they contribute to the process. As shown in the photo I was adding and labeling new pages so that I can explain the engineering process.
Today I tested the size of the nose cone. I had three different sizes; small medium, and large. My hypothesis was correct and the smaller the nose cone was the further the rocket went. I also found that the dependent variable was how far the rocket went and the independent variable was the size of the nose cones.
Day 1: I made 2 small rockets out of straws, clay, tape, and paper. I was testing to see if a longer rocket will go further than a shorter rocket. My independent variable was the length of the rockets and the dependent variable is the distance it travels. My hypothesis was correct and the longer rocket traveled the furthest.
