Colonization (per google): The action or process of settling among and establishing control over the indigenous people of an area; the action of appropriating a place or domain for ones own use
A while back it hit me: basically every alien movie, book, TV show or video game is about colonization.
Right around 1:05, we hear the speaker say, "When you invade a place for its resources, you wipe out its indigenous population. Right now we are being colonized."
And this is what colonization is - whether it's by aliens or people groups.
I told my students they could get extra credit if they posted a trailer in the comments showing an alien movie that depicted colonization. They can't use one that someone else used in comment above them, and it has to be school appropriate, of course.
