OK, elsewhere you've said you're somewhat of a beginner. Great instincts for a beginner!
So, another tip after Brian's: For outside shots where you want to keep the blue color of the sky, sometimes reduce the exposure compensation to perhaps -2/3, or even -1.
Some of your shots are fine for the sky, others have the sky over-exposed. (Sometimes over-exposure can sometimes be a good choice though. It depends on what you want for the shot.)
The tip is: try not to let the camera decide exposure for you, decide what you want and work the camera to get that for you.
The rest of the shot will be darker, but you can brighten where needed in picture editing software, later. But you can't recover the sky when it's been over-exposed (aka, "blown") to white.
You'll find most of my tips to not be specific to the "T." My favorite cameras, like the "T," allow me to make my exposure, shutter, ISO, focus, and aperture choices quite intuitively. So almost no tips needed for the camera itself!
By the way "exposure compensation" is you telling the camera how light or dark the picture will be from the camera. You can also tell the camera that with "manual" settings (versus the camera's automatic settings), but you don't have to dive into that just yet.
