I've been trying to do this lesson justice for a while now, and it's should be quite engaging.
It starts with an introduction, gives some useful vocabulary and how to use them in phrases.

The second half features three tour video of the popular theme parks in California: Disneyland, Knott's Berry Farm, and Magic Mountain.

The lesson ends with a discussion on the videos, and having students talk with their classmate about which theme park they feel they would like to visit.

There are some memos on the video slides. YouTube links should be working, if not, just let me know.

This is good lesson for upper elementary or lower middle school students.

Haven't tried it out yet, but it should be a good one!  :)

There's a slight type-o in one of the "phrases" slides. Should be easy enough to spot. Sorry about that.

Seeing this thread, I got the idea to narrow it down and do a roller coaster plan. My lesson was for 5/6 graders, but I'm sure you could change some things to bring it up to the middle school level. When I looked up info on making the track, I saw American high school students, so it can be applied to a range of ages.

The lesson was aimed at physics and I used words such as force, gravity, etc. Search the web for "pipe insulation roller coaster" blah blah blah to show the students.

My plan was written out for 4 hours, but I found out too late I only had 3, so consider your time-table. Give at least 2 hours for the students construct their track (plus discussion time after).

My co-teacher was able to find really cheap pipe insulation, so there were no real budget issues. 

Random thought: when it came time for the students to start building their tracks, I only gave them mild suggestions and tips, as the point of this was for them to explore and discover what worked and did not work. You could offer up a classroom computer or let them use their smartphones to look up track designs.

Okay I looked at other theme park ppts on waygook and I added more stuff to this powerpoint.  Basically I added more information about Disney Land and Orlando Studios, talked about rules/what is not allowed at a theme park and why. and added a few more vocabulary words.  I think I will make an angry bird game to test their memory on the things they learned and then it should cover a 45 minute class, no problem.  Maybe I will test the lesson out next week.
