What have you learned about the history of rockets and space travel? Write a summary on the blog about something or someone you found interesting and tell why.
I thought it was interesting how important rockets are. If it weren’t for rockets, we wouldn’t have progressed as far as we would want to thanks to satellites. Also, the legend about Wan Hu is interesting. Did he survive? Was it recorded in scriptures? I have so many questions about it.
Now that you know about the basic parts of a rocket and what they do, write about each part and its importance in your own words. What will be different on your water rocket than on a “real” rocket and why?
The first part of the rocket is the nose cone. It is crucial for the rocket to break through the atmosphere. Of course, we won’t be reaching that far, but it is still important to reduce air friction and drag.
The payload is the second component, you don’t need it for the functionality of the rocket launch but rather the functionality of carrying something. A human, for example, we won’t be carrying a human in our rockets, but instead, an egg and we need to make sure it lands safely.
The third component is the propulsion chamber. This is the engine of the rocket and is called the rocket. It is used to launch the rocket with the use of thrust, typically using rocket fuel. We will be using water and pressure as our fuel, unfortunately.
The fourth component is the fin. This is necessary for the continued stability throughout the flight. It makes sure that the rocket can zip through the air while being upright because it needs to go up. We are going to use fins in our rockets too.
Write a little on the blog about how to find the Center of Pressure and the Center of Gravity on your rocket and why they are important.
The center of pressure is found by spinning the rocket around on an attached piece of string in the middle of the rocket if it flies straight, then it will succeed, if not then you need to adjust the cone weight or fin size. The center of gravity is found by balancing the rocket on the side. If there is a balance, then the center of gravity is located there. this is important to find out because you can fix your rocket if it acts irrationally, for example, if it flies backward then the center of pressure is in front of the center of gravity, therefore, you can fix it.
Based on what you have learned about rocket design (nose cone & fins) describe what your rocket will look like and why you chose that design on the blog.
My rocket will have an egg-shaped cone because it will be more durable and have more balance, it will probably have 3 fins and will be tall. The reason why is because my last rocket was successful with that same design.
