This week we have been learning about flight. We have been looking at the four forces of flight, flying vs gliding, we brain stormed what is man-made and what is Natural. Also we have been looking at how some birds fly.
At the start I knew quite a lot of things. I knew about thrust and drag. But I didn't really know what they do, and where they go on a flying object. For example, thrust goes at the front of a plane, and drag goes at the back of a plane, so on. I also knew some other things like: what can fly, if those things are man-made or natural and etc. I knew that there are four forces to flight too. I had learnt a bit about it a couple of years ago, because we were focusing on this topic then too.
Now I know more about the four forces, where they go on a flying object, what they do to help flying objects fly and what all of them are/what they are called. Also at the start I thought that gliding was pretty much the same as flying. But now I know that it is not the same thing as flying. This is why: flight is defined as a controlled and powered movement/flight, through the air. Gliding isn't controlled or powered. Gliding is resting, and when a flying object or an object that is made to fly, kind of moves along with the wind. It's also kind of when the leftover thrust used to move the plane while flying, is used to move the flying object forwards while in the air, until it runs out.
In this time, I had observed that little birds need to do tons and tons of flaps with their wings so that they can go about the same speed as a medium sized bird can go, with a regular speed.
A couple of days ago we were looking at what the four forces of flight do. Thrust: the forwards force that helps a plane to move through the air. Drag: a force that helps the plane to slow down when needed. Lift: helps to keep a plane in the air, but still needs some weight, so that the plane doesn't just fly off into the air, and can't get down. Weight: helps the plane to slow Down, and keeps a plane from flying off high in the sky. Also you will need some lift too, so that the plane doesn't just crash while in the air, or stay on the ground.
One of my wonderings was: what would happen if you took away one of the four forces? I think that if you took away one of the forces on a plane that it would just crash. Because each of the forces help to keep a plane in the sky. So it would just crash, because you need all of the forces to keep a plane in the sky. Another wondering that I had was: is gliding the same as flying? This is one of the wonderings that I had when I first started this inquiry topic. I had explained the answer before, above. If you want to be reminded you can always just look back at the top. So I had those wonderings done, but then I had another wondering. That was: if you turned off an engine on an aeroplane, would the plane fall and crash straight away, or glide for a bit then crash? I am still thinking on this one. I think I might need to search that one up.
If I had to place myself in a rubric for my observations during this project, I think that I would put myself maybe in the middle of multistructural and relational. I can make some observations on this. But I am quite confident on them though. So that's why I put myself in the middle.
For my inferences I will probably put myself again in the middle of multistructural and relational, because I can make quite a few inferences, but I am confident on the accuracy and the reliability of my observations. I think I know why and when and how to do this so that my inferences make sense. So that's why I put myself in the middle of those two.
