Since you are in school, you will understand a criticism.
Silouette is spelled "silhouette".
A common spelling error.
Most silhouette photography is done in the late evening, just before the sun goes down.
With a bright sky and and a foreground that is not lit by the sun or a flash.
So rule one is....turn off the flash
Rule two is get the camera out of "Auto" mode.
You usually want to underexpose the shot.
I am not going to try to get too detailed because there are hundreds of people who have written a "how to" on the subject.
Go to Google.com
Type in "Silhouette Photography"
You will get a list of links to explore.
